In modern manufacturing environments, robotic arms play a vital role in improving productivity by automating repetitive and complex tasks around the clock. These robotic systems are not only programmable but can also function collaboratively as co-robots (cobots), working safely alongside humans.
To ensure accurate, stable, and controlled movement, robotic joints—driven by servo or stepper motors—must not only monitor position but also torque output. By integrating reaction torque sensors, engineers can develop feedback-based control loops that enable smooth, consistent, and autonomous operation.
🛠️ Products in Use
For this application, FUTEK provides the following solutions:
- TFF400 Reaction Torque Sensor
- IAA Series or IDA100 Amplifiers
These components form a reliable system for joint torque feedback and motor control.
🔁 How Robot Joint Control with Torque Sensors Works
- Sensor Installation
The TFF Series Reaction Torque Sensor is mounted between the servo motor and the robot arm’s frame or mounting points. - Torque Measurement and Signal Amplification
As the motor operates, the torque produced is measured by the TFF sensor. This raw signal is then amplified using FUTEK’s IAA Series or IDA100 signal conditioners. - Feedback to Control System
The amplified torque signal is sent to a PLC or robotic controller, where it helps close the control loop. This enables dynamic adjustments in real time for smoother, more precise joint motion. - Optional Monitoring and Software Control
For enhanced performance and diagnostics, the signal can be monitored using FUTEK’s SENSIT™ software, which provides real-time visualisation and digital calibration options.
⚙️ Why Torque Feedback is Essential
- Ensures smooth and precise joint movement
- Prevents over-torque conditions and wear
- Supports advanced robotic functions like force-limited collaboration in cobots
- Enables adaptive responses in dynamic environments
