DFRobot_TactileSensor

===========================

• 中文版

The tactile sensor is a device that can convert physical contact, pressure or force distribution information into measurable electrical signals, and is often regarded as the "electronic skin" of robots. It provides crucial tactile feedback to the equipment by sensing the magnitude, location distribution and even the changing trend of the pressure acting on its surface.
