The wireless energy transmitting end of a previous joint and a wireless energy receiving end of a next joint intwo adjacent joints perform wireless electric energy transmission through electromagnetic inductive coupling while performing data exchange through wireless communication, therefore, the electric energy transmission and data exchange are performed through a wireless mode between the joints, the access of a plug-in is not needed, the space mechanical arm is easily reconstructed, and the flexibilityof the mechanical arm joints is improved.

Description

technical field [0001] The invention relates to the technical field of robot power distribution, in particular to a wireless power distribution system applied between joints of a reconfigurable space manipulator. Background technique [0002] With the advancement of science and technology and the development of robotics, the level of automation in various fields is getting higher and higher, and more and more occasions use robots to replace humans to perform tasks and engage in production activities. In the engineering practice of robots, the most common robot application is to rely on multi-degree-of-freedom, multi-functional, reprogrammable manipulator operating systems with various types of end effectors to complete various expected tasks. However, due to its fixed configuration, limited scope of application, poor flexibility, long production cycle, and high cost, the traditional robotic arm is becoming more and more difficult to deal with some complex and changeable task...
