Abstract

The invention discloses a soft skeletal muscle driver based on a ferrofluid and an electromagnetic coil. Artificial skeletal muscle (I) is a cylindrical or semi-cylindrical shape, the interior of themuscle is in a grid hollow pipe design, and an artificial elastic fiber material is adopted; the ferrofluid (II) fills in the grid hollow pipe and can flow freely; the electromagnetic coil (III) is distributed on the surface of the artificial skeletal muscle (I), a flexible copper coil material is adopted, and the coil deforms and bends along with the artificial skeletal muscle (I); and the electromagnetic coil (III) is powered on and an magnetic field is generated, the ferrofluid (II) is promoted to be gathered in the different positions in the artificial skeletal muscle (I), the inner pressure is generated, bending and deformation of the artificial skeletal muscle (I) is achieved, and driving of soft skeletal muscle is achieved. Compared with current popular pneumatic artificial skeletalmuscle, the driver has the advantages of being high in controllability, light and convenient and no need of an extra pneumatic device.

Description

technical field [0001] The invention relates to a soft skeletal muscle driver based on ferrofluid and electromagnetic coils, which is applied to wearable exoskeleton robots to assist in the fusion of human bodies to complete complex heavy physical labor, or to provide disabled people with physical functions analogous to ordinary people. The technical field of bionic robotics. Background technique [0002] The exoskeleton robot is a new type of wearable robot. The wearer and the exoskeleton robot need to be integrated to assist in the work. Since the 1940s, countries such as the United States and Japan have begun to study artificial skeletal muscles and apply them to military reconnaissance, battlefield transportation and other fields. However, limited by traditional drive systems (hydraulic and electric motors, etc.), research on the safety, energy consumption and lightweight performance of wearable mechanical exoskeletons has not been greatly developed. As a result, in re...
