1. GENERAL INFORMATION

1.1.  What is ERC

The European Rover Challenge (ERC) is a contest for Student Teams. A Student Team has to design and build a Martian rover prototype and use that robot to compete in various Tasks at a designated location. The aim of the Challenge is to give the participants a chance to expand their knowledge of Martian exploration, provide valuable professional experience in different fields of engineering, project and team management, project documentation and presentation while also popularize STEM (Science, Technology, Engineering and Mathematics) especially space exploration and robotics among the wider public, including the Challenge audience.

The European Rover Challenge is organized by European Space Foundation and Planet PR Agency, also referred to as the Organizers, in cooperation with group of independent experts as a Jury. Mars Society Polska, a Polish non-governmental organization, is a Partner of the event.

 

1.2. Date and Venue

The ERC 2016 will be held September 10-12th, 2016 in Poland (for further information please follow updates on Challenge website (see 1.3)).

 

1.3. Information channels and contacts

The Challenge website address is: www.roverchallenge.eu

Teams’ Contact Point email address is: teams@roverchallenge.eu

 

 2. TEAMS

2.1.  General

The 2016 edition of the Challenge is planned for approximately 20 Student Teams. The Organizer and the Challenge Jury will choose which of the registered Teams are allowed to compete in the Challenge. The choice will be made based on Registration Proposals and preliminary Reports that the Teams are required to send to the Organizer which are described in section 4. The deadline for their submission are March 31st and May 5th respectively . The Organizer will announce which Teams have qualified for the Challenge proper by May 13th.

 

2.2.  Registration

Team Registration will be open from 20th January till March 31st. Registration details shall be sent to the Organizer in English, via Teams’ Contact Point e-mail address (see 1.3). If this document is not submitted in the form and within the time laid down, Team will not be allowed to participate in the Challenge.

The Team Registration e-mail shall include:

a) Name of the higher education institution with which the Team is affiliated (if the Team is affiliated with more than one institution, please list all the names, in descending order of involvement);
b) Team name;
c) Rover name (may be the same as Team name);
d) Project proposal – described in section 4;
e) Approximate number of Team Members who plan on coming to the Challenge (i.e. appearing on site);
f) Team Contact Point person name and surname, telephone number and e-mail address;
g) University Team Coordinator name and surname, telephone number and e-mail address;
h) Team website address or/and Facebook fanpage;
i) The following declaration, in English:

“By sending this message and registering the Team to the European Rover Challenge we fully accept all terms and provisions of the European Rover Challenge Rules and all final decisions of the European Rover Challenge Organizer.”

 

2.3.  Team members

Team must consist of higher education students and recent graduates only: undergraduate and graduate Masters-degree level students (with no limitations) and PhD students (but no more than half of the Team). It is recommended that Teams will cooperate with specialists from different institutions, but students must prepare and sign all the required documentation themselves.

A Team may consist of students of more than one higher education institution. An institution may also affiliate more than one Team. Team membership is exclusive – each person can be a member of only one Team.

 

3. ROVER SYSTEM REQUIREMENTS

Each rover must be compliant with requirements listed below to take part in the Challenge. Any non-compliance would cause disallowance to use the rover during field trials. It is highly recommended that Teams present this compliance in Technical Reports in transparent way.

 

3.1.  General requirements

The rover has to be a stand-alone, mobile platform. No cables or tethers are allowed for connection to external sources during its operation.

Teams must design and build their own rover, but COTS (Commercial-Off-The-Shelf) components are allowed.

 

3.2.  Rover weight

The weight limit for the rover during a Task is 50 kilograms. The limit applies to every Task (i.e. task-relevant rover configuration) separately. Equipment used for rover maintenance and preparation, unused spare parts, and elements not mounted during a particular Task are not included in this limit.

There is no weight limit on equipment used to steer and control the rover from the rover control area, communications equipment in that area or maintenance equipment.

If the rover will be lighter than maximum limit for every kilogram below limit a 0.5 point will be added to the score for each Task separately (but no more than 10 points). If a limit is exceeded, 1 point will be subtracted for every kilogram (but no more than 20 points). For scoring purposes, kilograms will be rounded upwards.

 

3.3.  Rover speed

The rover maximum speed should be not higher than 3 km/h.

 

3.4.  Rover control and operational range

The rover should be radio controlled, in real time. Each Task will require the rover to travel a certain distance, but never more than 100m from the starting point. The starting point will be no farther than 50 meters from the control station area. All communication equipment, including antennas, should be deployed in vicinity of control station.

 

3.5.  Rover autonomy

Rover autonomy or automation of single Tasks are not required but bonus points, specified in Task description, will be awarded for it.

In automated control below defined states and commands should be differentiated:

–  “start” command – command to be send at the beginning of the attempt;
–  “working” state – nominal work during attempt;
–  “wait” command – enter “wait” state. Team can use it at any time for sensor readings stabilization;
–  ”waiting” state – rover should wait still for “resume” command. This state should be automatically entered if rover reaches check-point. System should be prepared that during this state sensors can be obstructed by Judge or Team members presence in rover vicinity (e.g. checking distance to the check-point). Operator cannot influence a system during this state. Reaching this state do not stop Task time;
–  “resume” command – transition from “waiting” to “working” state;
–  “stop” – rover immediate stop – control can be switched to manual.

This list is not exhaustive and Teams can define additional states and commands.

In order to achieve points for autonomy or single Task automation, Teams can not touch the controls once the attempt begins. The only exception is to send commands listed above. If Team members touch the controls, then the autonomy points for that attempt will not be awarded. However, Teams may revert to manual control to complete the Task. Telemetry to monitor the rover operation could be received during autonomous operations.

 

3.6.  Emergency stop button

The rover shall be equipped with an easily accessible red emergency stop button. It must be highly reliable and immediate. Therefore, an unmodified, commercial off-the-shelf, emergency stop button is required. The button action has to isolate the batteries from the system. If an unsafe event occurs, Judges will hit this button.

 

3.7.  Communication requirements

3.7.1. General

Radio communication with the rover has to use legally available frequencies and legal power levels. ERC expects that maximum distance between rover and control station would be less than 100m.

3.7.2. Typical frequencies accepted by ERC

3.7.2.1. Radio amateur bands

Accepted bands up to 1 W signal transmitted to antenna and up 10 W EIRP (Equivalent Isotropic Radiated Power).

0144.000-0146.000 MHz

0430.000-0440.000 MHz

1240.000-1300.000 MHz

5650.000-5850.000 MHz

Remark 1: ERC highly recommends that each Team should have at least one member with radio amateur license CEPT class T/R 61-01 (http://www.arrl.org/files/file/cept-ral.pdf). If there is no radio amateur with this license type in the Team and the Team wants to use radio amateur bands, they can ask radio amateur from ERC Team for help, but any action (any transmitter switching) using this frequencies should be accepted by this radio amateur first.

3.7.2.2. WiFi 2.4 GHz

Accepted channels: 1-13 (2412 MHz – 2472 MHz) up to 100 mW EIRP

Remark 1: At 2.4 GHz band ERC accepts WiFi communication standard only. We do not accept other systems like analog video cameras or RC controllers. System must be ready for connection and operation in 812.11g WiFi standard.

Remark 2: Teams should be careful about maximum RF power limit of 100 mW EIRP. For example: if robot uses 10 dB gain antenna, then it can use up to 10 mW RF feeding signal.

Remark 3: At 2.4 GHz band rover can use only one 20 MHz WiFi channel, and it will be selected by Judges (depending on the current occupancy and time).

Remark 4: SSID name should be set to “<erc_teamname>”.

3.7.2.3. WiFi 5.6 GHz

Accepted channels: 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140 (5260 MHz – 5700 MHz) ) up to 100mW EIRP.

Remark 1: If Team uses WiFi frequencies (for example for RF video transmitter or for WiFi communication), it should be ready for changing frequency to another channel.

Remark 2: If Team uses WiFi technology its SSID name should be set to “<erc_teamname>”.

3.7.2.4. ISM bands

Remark 1: It is possible to use ISM bands (https://en.wikipedia.org/wiki/ISM_band) within their RF power limitations (typically 1 or 10 mW) but Team must show which Polish regulation they use (in Poland there are several regulations in this subject and those depend on different RF power limits, modulation, usage area etc.)

Remark 2: ERC does not accept ISM bands used in USA which are not accepted in Poland (e.g. 915 MHz).

3.7.2.5. For voice communication using 500 mW PMR licensed transceiver

Channel Frequency (MHz)

  1. 446,00625
  2. 446,01875
  3. 446,03125
  4. 446,04375
  5. 446,05625
  6. 446,06875
  7. 446,08125 – reserved for organising team
  8. 446,09375 – reserved for organising team3.7.2.6. Other frequencies

Any other frequencies are possible if Team has licenses for those and those licenses would be accepted by RF communication Judge. However, powers and frequencies will be limited to those proposed by ERC in order to ensure fair play competition with other Teams.

3.7.3. Other communication rules

Remark 1: Before the Competition, rovers and ground stations must be checked and accepted by radio communication Judge after passing EMC (electromagnetic compatibility) test.

Remark 2: During Competition, rovers and ground stations will be randomly EMC tested.

Unauthorized changes to the RF configuration may result in disqualification.

3.7.4. Radio Frequency Form

Each Team must fill Radio Frequency Form for any RF module used. It shall be included in relevant Technical Reports as an appendix (see 4). If these documents are not submitted in the form, Team will not be allowed to participate in the Challenge.

RF Form shall contain:

a) Team name;
b) Country;
c) How many different communication system will you use?;
d) Name of the person responsible for communication system;
e) Contact to the person responsible for communication system (e-mail address);
f) Photo of the rover;
g) Photo of the ground station;
h) System information (multiply this part for any RF system):

  • RF system name;
  • Frequency;
  • Bandwidth;
  • RF transmit power;
  • Modulation;
  • Short description.

 

i) RF spectrum analyses when all systems (on rover and ground station) are on. Spectrum analyses must be measured from 100 kHz up to double frequency + 1 GHz used by Team (for example if highest band used is 2.4 GHz, Team has to measure pattern up to 2.4*2+1= 5.8 GHz);
j) RF spectrum analyses in the same frequency range when all systems are off;
k) RF antenna radiation pattern for rover;
l) RF antenna radiation pattern for ground station.

Radio

Pic. 1.: Example of the RF spectrum analyses

Radio2

Pic. 2.: Example of the Horizontal and Vertical RF antenna radiation pattern for ground station

Remark 1: It is advised to measure RF spectrum analyses and antenna radiation in RF anechoic chamber but it is not obligatory.

Remark 2: If Team provides RF form after deadline, they will be not frequency coordinated. ERC will prepare special competition time window (typically in the morning, which is highly unpopular time) for uncoordinated Teams. Team still has to be checked by ERC (for passing RF regulations) before the Competition starts but if Team would be causing interferences for other uncoordinated Teams it will be not fixed.

Remark 3: For the whole duration of the ERC Challenge, the Team is responsible for the legal use of frequencies in Poland. ERC can only help in frequency coordination, but does not take responsibility for any license violation (may it be exceeding RF power, frequency band or area of use).

Remark 4: If Team has not enough experience to estimate/measure such properties, it is highly recommended to consult this point with specialists from your or cooperating institution with such specialisation.

 

3.8.  Budget requirements

Nett cost of the rover cannot exceed 15 000 Euros. If expenses are paid in another currency, the exchange rate from January 20th 2016 should be used. The cost limit applies to payments for rover parts, equipment and any paid work done on the project (e.g. paid services, paid work hours). It does not include tools, volunteer work and Team travel expenses.

Teams may have sponsors or donors who provide them with money, tools, parts or equipment. Such donations and sponsorships must be properly documented and included in the rover cost balance. If Team receives tools, parts, equipment or any other asset that is not cash, standard market value must be used when calculating its value.

d) The spaces will be numbered and assigned to Teams through a draw for the whole duration of the contest;
e) Challenge location will be separated from Teams area to avoid RF interferences;
f) The Challenge field, where field Tasks will be held, will be artificially landscaped specifically for the Challenge. Sandy, non-cohesive soil as well as hard, dry terrain should be expected. The rover should be built to handle such terrain including appropriate dust resistance and a temperature tolerance of at least 10 to 30 degrees Celsius.

 

5.4.  Operations

a) Teams will control their rovers from rover control areas designated for them on site. The areas will be set up so that Team Members will not see their rover during the tasks;
b) Each Team will have maximum 25 minutes (if Task description does not state different) to complete each Task;
c)Each Team must designate two Observers, who will be allowed to follow the rover at a safe distance to ensure the machine’s basic safety, but the Observers will not be allowed to communicate with the Team Members in the control area. Observers must be able to carry rover but they should stay in safe distance from the working machine and cannot interfere with any rover’s sensors (e.g. be visible on the image from the camera) during realisation of the Task attempt;
d) During tasks only Judges and Team’s Observer can access field of the task. No manual intervention is allowed except events for which Task rules stand different;
e) Any maintenance made by the Team during Tasks (any operations made by the crew/Team with rover’s hardware in the field) causes starting the Task from the beginning and cancellation of the all earned points;
f) The Team can use video systems to navigate the rover if Task requirements does not state different;
g) The Team shall not use any voice/visual communication with the crew in the field. No radio/internet/other communication is allowed. The Judge will be equipped with radio communication system which Observers can use to contact with the rest of the Team in operation center;

5.8.  Navigation task

This task is intended to demonstrate rovers and Teams ability of approaching locations on the field with limited or without supervision. The Team has to develop a system which will allow operator to navigate rover without access to visual data such as video streaming, photos and other sensor sources placed on the rover that are presenting visual information. However, any kind of data can be processed on-board to provide to operator localisation and operation support information. The smart navigation strategy, sensor fusion and image data processing are essential in this task.

5.8.1. Goals

a) Reach sequentially 4 check points (A > B > C > D);
b) Bonus: reach additional point located in more challenging terrain;
c) Present advanced techniques in navigation, data presentation, on-board processing, etc.

5.8.2. General requirements

a) Navigate rover, without information from imaging systems, using information detailed on the map and data received from the rover;
b) Rover starts from the start point with orientation perpendicular to the start line;
c) Any kind of sensor (i.e. camera, lidar, IMU, odometer, sonar, etc.) can be used for on-board processing. However GNSS receivers are not recommended since the navigation task will be performed indoor (under glassy roof adjacent to concrete building) which may result in limited access to GNSS signals and/or strong multipath effects;
d) All data from imaging systems (camera, laser scanner, etc.) shall be processed on-board (i.e. cannot be broadcasted to the control room). However, derived information (e.g. result from image recognition algorithm) can be provided to the control room;
e) If for some reason rover has to be moved, it can only be moved (penalties applied):

  • back to the last safe position (assistants define it) and/or rotated towards any point;
  • back to the last successfully reached check-point and/or rotated towards any point;
  • back to the start point.

 

5.8.3. Expected results

a) Reach all check-points;
b) Presentation of system that support operator in rover control;
c) Bonus: reaching check-point X;
d) Bonus: successful autonomous traverse between at least two check-points.

5.8.4. Additional information

a) Technical Reports shall include a list of all sensors together with detailed information about working modes, ways they are used in navigation task and which data will be presented to the operator. Teams are entitled to consult all solutions with Judges before documentation submission. Documentation will be verified by Judges and in case of any doubts Team could be asked to reconfigure devices and/or communication strategy. Any difference between approved configuration and the one used during Challenges can cause a disqualification (0 points for this task);

b) Task arena:

–  Final map with grid coordinates and POIs (Point Of Interests) will be provided not later than 3 days before the Competition;
–  Most landmarks will be visible from starting point but it must be taken into account that part of them could be obscured by terrain or other objects during traverse;
–  Two types of landmarks are foreseen: natural landmarks which are elements of landscape placed on the map, e.g. craters, small embankments, hills and artificial landmarks, e.g. artificial points for localisation purposes with characteristic hi-visibility labels with characteristic logotype, unique geometric figure and alphanumeric sign matching POI label on the map;
–  Artificial landmarks will be visible for camera from different direction on a field and will have physical base which can be detected by proximity/range sensors (e.g. placed on element of infrastructure or natural landmark);
–  Check-points will be flat characteristic elements with similar labels like on artificial landmarks;
–  Final definition of the check-points and landmarks will be provided not later than 30 days before the Competition;
–  Team cannot place any additional passive landmarks or active beacons on challenge field outside starting area but such elements can be deployed using rover during trial. All those landmarks must be documented in Technical Reports and presented for Judges acceptance at least 10 working days before submission of the final documentation. These equipment can be subject of negotiations so Teams should leave enough time to redesign/modify it in case of comments/rejection by Judges. Such equipment must comply with other rules of the Competitions (especially 5.4 i)) and if active radio beacons are used, they must be compliant with radio communication rules (see 3.7) and described in RF form;

c) Rover can be stopped and moved/rotated by Team members when it is stuck or in case of any other technical problems. Judge has to be informed before any action is undertaken;
d) During Task attempt several photos of the current state of the Field will be delivered to the Team by Judge. Photos will be delivered periodically but the frequency does not allow Team to accurate navigate their rover. Photos will be taken from static position (in perspective, top-view or both) and can be used to correct control methodology by operator or control software;
e) Details of the task such as landmarks appearance, location, map format, allowed custom landmarks and beacon types etc. will be discussed with the Teams and presented in the FAQ during registration and preliminary design phases. Teams are encouraged to initiate, take a part and follow outcomes of those discussions.

5.8.5. Scoring (100 points + 50 bonus points)

a) Reaching the control point: 25 – (5 * floor(d)) points, where d is a distance (in meters) between an actual control point and nearest element of the rover structure. The rule is only applied if d<5m. Distance will be measured on request after Team (or rover software) declares reaching a given check-point. The measured distance will be provided (without any other indications) to the control site. (max 25 points).

b) Penalties

–  In case that measured distance between the current control point and rover is equal or greater than 5m, Team will be asked for another attempt. Once the distance is less than 5m no other attempts (to minimize distance) are allowed – rover can go to the next control point (-5 points);
–  Moving rover back to the start point, the last successfully reached check-point or the last safe position (-5 points);
–  Any non-authorised communication between assistants and control site (-25 points).

Total score for this task cannot be less than zero

5.8.5.1. Bonus tasks

Judge must be informed in advance – before Team proceeds to the optional task.

a) Reaching the hardly accessible check-point marked by X (the same rules as for the regular A,B,C,D points are applied) – bonus check-point can be reached either in a way from A to B or from B to C (max 25 points);

b) Autonomous traversal (max 25 points):

–  Autonomous traversal from start point to check point A – 5 points;
–  Autonomous traversal from A to B or A to X or X to B or B to C or C to D – 10 points (no more than 2 traversals will be scored).

Distribution of bonus points for autonomous traversal can change according to the final definition of the operational area.
