A bionic mechanical hand based on mesh linkage structure

Abstract

The invention discloses a bionic mechanical palm based on a mesh linkage structure, which includes a thumb, index finger, middle finger, ring finger, little finger, and palm. The operator wears a special data glove on the hand, and binds the data sending module to the forearm with an elastic nylon strap. A bending sensor is integrated inside the data glove, which reads the bending angle of each finger of the operator in real time and transmits the signal It is transmitted to the processor on the glove side for combined processing, and the data glove wirelessly transmits the instructions to the bionic robot palm, so as to realize the real-time control of the bionic robot palm by the human hand.

Description

Technical field [0001] The invention relates to a bionic manipulator palm, in particular to a bionic manipulator palm based on a mesh linkage structure. Background technique [0002] With the popularization of robots, industrial manipulators have replaced many workers and occupy half of the factory. Industrial manipulators are mechanical electronic devices that anthropomorphize arms, wrists and hand functions. It can move any object or tool according to the time-varying requirements of spatial pose (position and posture) to complete the operation requirements of a certain industrial production. Such as clamping welding tongs or welding torch, spot welding or arc welding of automobile or motorcycle body; handling die-cast or stamped parts or components; laser cutting; spraying; assembling mechanical parts and so on. The advantages of industrial robotic arms are precise positioning, high stability, and the ability to accurately repeat simple or complex manufacturing, processing, a...

Problems solved by technology

Among them, pneumatic and hydraulic have high requirements on the maturity of equipment technology, so the cost is also high, and it is difficult to take into account the accuracy under the condition of ensuring the output torque

Although artificial muscles are technologically advanced, they are also extremely expensive to manufacture

The wire-pull drive takes into account the positioning accuracy while ensuring the output torque, but due to the complex internal structure, it is time-consuming and laborious to assemble, and the stability is not good

For example, the patent with publication number CN 105583829A introduces a simulated mechanical finger based on steel wire pulling, which has the advantages of high precision and high output torque, but because it is based on the principle of wire pulling, the power device must be embedded in the arm, so that Deficiencies that lead to insufficient flexibility in the wrist
