User-Made Servo Gripper Force Sensor Board Seeks Testing
1 reports · 1 sources
Reddit user /u/Motor_Artichoke_7355 showcased a homemade Grip Sensor board in r/robotics that estimates grip force by measuring servo current, giving basic PWM servos a sense of touch, and says 5 boards are ready for others to request for testing via private message. The board features a status LED indicating whether an object has been grasped, and a Teach button that lets users teach the force level while gripping an object, which is automatically remembered next time; an open-drain status output can communicate with existing MCUs. The author says it is suitable for gripping fragile soft objects and can prevent overheating of the servo caused by gripping too tightly. In the video demonstration, when the box gripped by the servo drops, the board detects this and notifies the MCU.

- Grip Sensor: a sensor board that gives PWM servos a sense of touch
A Grip Sensor board gives basic PWM servos a sense of touch by measuring servo current to estimate grip force. A status LED indicates whether an object has been grasped, a Teach button lets users teach the grip strength, and an open-drain status output can communicate with existing MCUs. In the video demo, the servo grips a box; when the box drops, the board detects it and notifies the MCU, while also preventing the servo from gripping too tightly and overheating. The author has made 5 boards for testing, available by direct message.
