Robot Joint Control using Torque Sensors

Application Summary on Robot Joint Control Measurement

Versatile and adaptive robotic armatures have the benefit of increasing manufacturing productivity.  Firstly, by automating and performing complex, repetitive tasks 24×7. Secondly, the arms are trainable.  Or operate as a team as cooperative robots (cobot/co-robot). Driving these arms in their joints are servo or stepper motors. In addition to monitoring shaft position, these arms need to monitor torque output for smooth, steady motion. Therefore, by combining these motors with a reaction torque sensor, control loops can be developed for smooth, autonomous operation.

How Robot Joint Control Works

  1. Mounting the TFF Series Reaction Torque Sensor is between the robot arm servo motor and its mounting points.
  2. The torque sensor measures the torque outputted during arm movement which is then amplified by the IAA Series or IDA100 amplifier.
  3. The PLC or robotic arm controller receives the amplified signal, providing precision feedback and closing the control loop.
  4. Additionally, the output can be monitored. Plus the FUTEK’s SENSIT™ Software can digitally adjust.
