Background
With the rapid development of artificial intelligence technology, opto-mechanical and mechanical integration and robot technology, the driving technology is more and more important. The robot driving joint is required to have higher flexibility, flexibility and compact structure, and the performance of the joint driving system determines various performance indexes of the robot, such as bearing capacity, appearance structure and the like, so that the selection of the driving system is very important for the design of the robot joint. The joint driver of the robot commonly used at present comprises a motor, pneumatic, hydraulic, human muscle made of new materials such as shape memory alloy, piezoelectric ceramics and the like. The traditional motor has low power/weight ratio, and a speed reducing mechanism is usually required to reduce the speed and increase the torque output, so that a transmission system is complex and the layout is difficult. Pneumatic muscle is a main driving mode of a pneumatic system for robot joint driving, and has simple and compact structure and low installation accuracy requirement, but an air supply pipeline is not separated, so that the moving range of a robot is limited, the resistance loss is increased, the control accuracy is reduced due to the overlong air supply pipeline, and accurate position and speed control is difficult to realize. The traditional hydraulic pressure has great advantages in the industrial robot joint driving, but the control system is huge, and meanwhile, the traditional hydraulic pressure is difficult to apply in the fields of mobile robots and the like due to the arrangement problem of oil (or gas) sources like pneumatic transmission of pneumatic muscles and the like. The artificial muscle made of new materials such as shape memory alloy, electrostriction, piezoelectricity and the like has the advantages of small volume, high output power, simple structure and the like, and has development prospect.
How to further develop the execution efficiency of the shape memory alloy in the driver, how to combine the shape memory alloy with the new nano material to further improve the driving efficiency, how to realize remote non-contact control driving in the fields of artificial intelligence technology, opto-mechanical integration and robotics, etc., and the technical problems are to be solved.
