Strain Gauge Neural Network-Based Estimation as an Alternative for Force and Torque Sensor Measurements in Robot Manipulators

Applied Sciences, 2023
When a robotic manipulator interacts with its environment, the end-effector forces need to be measured to assess if a task has been completed successfully and for safety reasons. Traditionally, these forces are either measured directly by a 6-dimensional

An experimental study of the sensorized strain wave gear RT1-T and its capabilities for torque control in robotic joints

Frontiers in Robotics and AI
The idea of sensorizing a strain wave gear to measure the transmitted torque has been reported since the 1980s. The strain in the elastic flex spline is typically measured by strain gages attached to it.

Behavior of hysteresis in magnetostrictive torque sensors.

Journal of the Magnetics Society of Japan, 1990
The hysteresis behavior of magnetostrictive torque sensors was investigated. Various kinds of steel were applied to driving shafts with sets of parallel grooves. Single magnetostrictive output (mode I, II output) obtained from tensile and compressive stress, and differential output obtained from differentiated mode I, II output, were observed. The mode
