Problems solved by technology

However, because the control of electromagnetic force is not as accurate as traditional hydraulic systems, and if you want to adjust the electromagnetic force, you need to cooperate with complex current and magnetic field adjustment devices, and the cost will increase instead.

Abstract

The invention discloses an artificial muscle device which comprises a coil framework, wherein a first permanent magnet is movably inserted into the inner side of the coil framework; a first electromagnetic coil is wound around the outer side of the coil framework; a magnetic yoke is arranged on the outer side of the first electromagnetic coil; a limiter is fixed on the first permanent magnet; thelimiter and the magnetic yoke are in sliding contact with each other; a sliding groove is formed in the surface of the magnetic yoke; a plurality of electromagnetic dampers are arranged on the contract surface between the limiter and the magnetic yoke; each electromagnetic damper and the sliding groove are in selective contact with each other; the electromagnetic dampers and the first electromagnetic coil are connected onto one and the same main power supply controller; and a branch power supply controller is independently arranged on each electromagnetic damper. By adoption of the artificialmuscle device disclosed by the invention, defects in the prior art can be overcome, and the motion control accuracy of electromagnetically-driven artificial muscle can be improved.

Description

technical field [0001] The invention relates to the technical field of bionic robots, in particular to an artificial muscle device and a driving method thereof. Background technique [0002] The traditional robot joint drive consists of a rotating motor and a reduction transmission mechanism. First of all, this kind of driving structure is complicated, and it needs to be built into the joint, so it is not easy to design and install. Simultaneously, the cushioning capacity of the drive of the rotating joint basically has no, so it is easy to be damaged. Furthermore, the self-locking function of this joint is weak and requires an independent mechanism or precise control. These three points directly cause the low applicability and high cost of traditional joint drives, and have become one of the bottlenecks in many industrial projects, such as Robotics. [0003] In recent years, artificial muscles have gradually become one of the research hotspots. The artificial muscles th...
