After some further development, Tethys Robotics had the opportunity to test the Proteus with the Swiss Military EOD team. The tests took place in Lake Thun where the EOD team already has some operations. The goal of the tests was to find the further features needed in Proteus to make the support for the EOD team more efficient. Furthermore, the localization system was tested in a real-world environment for the first time. The idea is to develop a sensor-fusion algorithm to combine our sensors and increase the accuracy of the robot’s positioning.
