3.3 Sensor: the core sensing component

Sensors are the core sensing components in humanoid robots, which can be likened to human sensory organs. A sensor is a measuring device or device that can sense a variety of non-electric quantities (such as LTC745A101-3BHE039905R0101 physical quantities, chemical quantities, biomass) and convert it into another physical quantity (generally electricity) for easy transmission and processing according to certain laws. The sensor is usually composed of a sensitive element and a conversion element, in which the sensitive element refers to the part of the sensor that directly senses the measurement, and the conversion element refers to the part where the sensor can convert the output of the sensitive element into an electrical signal suitable for transmission and processing.

Torque sensors are the most widely used in humanoid robots. According to the role of the sensor, the sensor is generally divided into internal sensors and external sensors. Internal sensor (body sensor) mainly measures the state of the internal system of the robot; External sensor (detection of external environment sensor) installed on the robot or mobile robot, mainly to measure the external environment of the robot. According to the classification of detection methods, the sensor can be divided into optical, mechanical, ultrasonic, resistance, semiconductor, capacitance, pressure and other sensors. In the Tesla Optimus robot, there are 40 torque sensors and three vision sensors, and sensors account for 19% of the total value.
