ATI Developing Force/Torque Sensing Technology for NASA - Robotics Online - ATI Industrial Automation was recently selected by NASA to develop Multi-Axis Force/Torque Sensing Technology that can be used in space exploration, like the Mars 2018 Mission. Currently under development, this new technology will enable fabrication of a Force/Torque Sensor for the Mars rover's robotic arm. Sensor feedback would allow the arm to guide its coring tool into rocks and then safely place the rock samples in the rover's canisters. There are a number of potential NASA applications for this new Sensor, providing valuable force feedback to a teleoperated robotic arm on the International Space Station or for providing loading feedback for limbs in a humanoid robot application ...
