We're having a great field campaign in Sudbury. TReX, our tethered climbing robot, has completed several descents down steep terrain in order to build three-dimensional models using lidar. The robot has performed quite well, and we've become more confident in the strength of the tether over time. The ability to drive sideways while under tension has proven an important capability to get around obstructions such as rock bulges. Overall, we're happy with the TReX concept and hope to make a smaller, lighter machine in the future to simplify logistics.
