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.
