Frog-imitation robot hip joint

Abstract

The invention discloses a frog-imitation robot hip joint, and belongs to the technical field of robotics so as to solve the complex problems that an existing frog-imitation robot hip joint cannot divedownwards and floats upwards due to the limited moving ways that the existing frog-imitation robot hip joint can only drive the leg and withdraw the leg in the horizontal direction and cannot carry out backward posture adjustment due to the fact that the existing frog-imitation robot hip joint only has one rotational freedom in the horizontal plane. The frog-imitation robot hip joint includes a transmission shaft, a first power mechanism, a transmission mechanism, a transmission rod, a left leg connecting module, a right leg connecting module, a left leg connecting rod, a right leg connectingrod, a left leg folding driving mechanism, a right leg folding driving mechanism, a second power mechanism and a machine frame; the transmission shaft mounted on the transmission mechanism on the machine frame in a driven mode and the left leg connecting module mounted at the output end of the transmission mechanism rotate synchronously, and the right leg connecting module is mounted on the machine frame and can rotate synchronously with the left leg connecting module for carrying out the curled-up motion; and the left leg connecting module and the right leg connecting module can rotate in the opposite directions for carrying out the folding motion. The frog-imitation robot hip joint is used for the frog-imitation robot.

Description

technical field [0001] The invention belongs to the technical field of robots. It specifically relates to the hip joint of a frog-like robot. Background technique [0002] About 71% of the world's area is covered by oceans, which contain abundant resources. With the rapid development of human economy and technology, land resources are rapidly depleted. The importance of the utilization of marine resources has attracted more and more people's attention, and the plan to explore the sea has also been put on the agenda by more and more countries. In the future, there will be more and more demands for scientific research and military security such as deep-sea resource exploration, monitoring and alarming of oceans and lakes, underwater biological research, emergency rescue, disaster relief, anti-terrorist blasting, etc. However, oceans and lakes are covered by water, and the internal situation is complex, which is different from the structured known environment of land. For di...

Problems solved by technology

[0007] The present invention aims to solve the problem that the hip joint of the existing frog-like robot has only one degree of freedom of rotation on the horizontal plane, and can only perform leg kicking and retraction movements in the horizontal direction, and cannot perform backward posture adjustment. The problems of complex movements such as diving and floating, and then propose a frog-like robot hip joint
