Abstract

The invention provides a bionic force drive device. The device is designed by referring to the living body skeleton and muscle structure. The bionic force drive device comprises a drive assembly and an action assembly. The action assembly comprises a fixed end rod and a free end rod, wherein the fixed end rod and the free end rod are connected in a rotating manner. The drive assembly comprises anelastic unit and a drive unit. The two ends of the elastic unit are fixedly connected to the fixed end rod and the free end rod correspondingly. Filler is contained in the elastic unit. The drive unitcan control input and output of the filter, thus the elastic unit can deform, during deformation of the elastic unit, the two ends of the elastic unit drive the fixed end rod and the free end rod torotate relatively, and use is more flexible compared with a traditional drive manner. The invention further provides a control method of the bionic force drive device. Output fore of the device can becontrolled precisely.

Description

technical field [0001] The invention relates to the field of bionic machinery, in particular to a bionic force driving device and a control method thereof. Background technique [0002] Skeletal muscles can flexibly control human body movement through self-contraction and stretching, and the force is sustained and explosive. Not only that, but skeletal muscle also protects brittle bones from being broken by gravity. At the same time, skeletal muscle has adaptive ability. As the frequency and force of use change, its contraction ability changes accordingly to adapt to stronger strength and drive requirements. [0003] Existing mechanical arms or motion devices with flexible requirements are driven by motors, pneumatics, hydraulics, etc. Pneumatic and hydraulic drives have strong explosive force, but the accuracy and continuity of the force cannot be guaranteed. Motor drives control devices that require strong output. Weak. [0004] Existing robots can replace humans to comp...
