Application Summary on Robot Joint Control Measurement
Versatile and adaptive robotic armatures have the benefit of increasing manufacturing productivity by automating and performing complex, repetitive tasks 24×7. These arms are often designed to be 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 it Works
- A TFF Series Reaction Torque Sensor is mounted between the robot arm servo motor and it’s mounting points.
- The torque sensor measures the torque outputted during arm movement which is then amplified by the IAA Series or IDA100 amplifier.
- The amplified signal is then sent to the PLC or robotic arm controller, providing precision feedback and closing the control loop.
- Additionally, with the IDA100, amplified output from the sensor can be monitored and analogue amplifier settings can be adjusted digitally with FUTEK’s SENSIT™ Software.
