Electromagnetic balance perception sensor for robot head self-energizing

Abstract

The invention discloses an electromagnetic balance perception sensor for robot head self-energizing. The electromagnetic balance perception sensor comprises a magnetic ball, a spherical shell, external conductive coils, a small magnetic block and an electrical test system. The conductive coil clings to the surface of the spherical shell and is connected to a voltmeter through a wire. In order to stabilize a magnetic axis of the magnetic ball, the small magnetic block is arranged at the bottom of the spherical shell. The spherical shell is fixed to the robot head, and when the robot moves, themagnetic ball in the sensor and the external coil can generate relative displacement. According to the law of electromagnetic induction, the five external coils can generate different voltages, the change direction of the magnetic ball and the change of relative displacement can be known according to the relative magnitude of voltage, and then the change of the robot motion state can be known. Theelectromagnetic balance perception sensor is simple in structure, good in stability and wide in application range, can achieve self-energizing, can detect the motion state of the robot head in real time, all the materials are industrialized materials, the cost is low, and good practicability is achieved.

Description

technical field [0001] The invention relates to an electromagnetic balance sensing sensor used for self-supply of a robot head, belonging to the fields of electromagnetic technology and acceleration sensors. It uses the change of relative position to convert mechanical energy into electrical energy and output differential electrical signals to detect the motion state of the object under test. Background technique [0002] With the development of science and technology and the improvement of people's living standards, robots are playing an increasingly important role in people's production and life. At present, robots have begun to replace humans in some simple and repetitive tasks, such as sorting express delivery and operating robotic arms in processing plants. In the near future, robots will replace humans to do some complicated and heavy work. Naturally, this also puts forward higher requirements for the robot's perception of itself and the outside world.

Problems solved by technology

However, there are still relatively few sensors for robot perception based on electromagnetic induction, and more efforts and investment are still needed to realize the robot's head balance perception, including the size and direction of motion.
