Taprobane V3.0 is a team representing the Students for the Exploration and Development of Space (SEDS) Sri Lanka for the ERC 2022 with over 50 students from 15 Sri Lankan universities. Crossing milestones as Taprobane 1.0, 2.0, and now 3.0, we are the first to build a rover from Sri Lanka. Taprobane 1.0 was the first Sri Lankan Mars rover to compete in the ERC 2019 competition, presenting only technical reports and finishing 29th in the ERC 2019 and 15th internationally in the International Rover Design Challenge 2020 rankings. Its next stage, the Taprobane 2.0, finished in 8th place in the International Rover Challenge (IRC) 2019 rankings with around 465 points. The next milestone in this journey is the Taprobane V3.0 with the aim of participating in the European Rover Challenge – 2022 and achieving success. We hope to be pioneers in Sri Lankan rover technology through this project, and we are looking forward to a remarkable breakthrough in the Sri Lankan space industry.
