Robot arms learn force sensing without costly hardware

Researchers have developed a new method called Neural External Torque Estimation (NEXT) that allows commodity robot arms to estimate external joint torques without requiring expensive dedicated force sensors. This technique trains quickly using only free-motion data and achieves accuracy comparable to traditional sensors. The method is integrated into a system called Force-Informed Re-Sampling Training (FIRST), which significantly improves policy learning for contact-rich manipulation tasks, leading to over 17% better task progress on complex challenges. AI

IMPACT Enables more sophisticated manipulation and control in low-cost robotic systems without additional hardware.
