Researchers evaluated Force-Torque Sensors (FTSs) on the European Space Agency's MaRTA rover in a planetary analog environment, demonstrating their superior performance over IMUs for terrain classification and analyzing their utility for drawbar pull estimation. The study generated an open-access dataset (BASEPROD) to inform future rover sensor suites.
Key insights
- FTS data offers richer, more direct information about wheel-terrain interaction, leading to significantly better terrain classification compared to IMU data.
- Directly estimating drawbar pull from raw FTS data in dynamic, unstructured environments is challenging due to noise and requires sophisticated filtering or dedicated ground-truth validation.
- While FTSs enhance terrain classification, simpler sensors like motor current may suffice for basic slip detection, indicating a need for a cost-benefit analysis in future rover sensor suite designs.
