Abstract

The invention provides a reversible and amphibious multi-legged robot with variable postures. The robot comprises three parts, i.e. a body bracket, a one-way input and vertical output module and a leg mechanism, wherein the one-way input and vertical output module is installed on the body bracket, and the leg mechanism is installed on the one-way input and vertical output module. The reversible and amphibious multi-legged robot with variable postures of the invention is formed by the parallel connection of a plurality of walking legs, and by controlling a posture adjustment motor, the real-time change of the standing and moving postures of the robot can be realized, thereby improving the capability of adapting to the complex amphibian environment; and each walking leg is formed by the serial connection of the one-way input and vertical output module and the leg mechanism. A tridimensional force sensor is installed at the leg end and is used for feeding back the stress of the leg end during movement, so as to realize the closed loop control of the stress of each leg of the robot.

Description

(1) Technical field [0001] The invention relates to a robot structure, in particular to a multi-legged robot structure. (2) Background technology [0002] Harbin Engineering University has launched basic technology research on bionic robot crabs since 1999, and has developed various types of products so far. Wherein more advanced is the technical scheme that the patent application number is 200710072364.0, (publication number: CN101088835) record in the patent application document. However, these types of multi-group robots also have the following common disadvantages: (1) the posture is not variable, and the adaptability to the amphibious environment is poor; (2) it is necessary to overcome the gravity of the leg motors to do useless work when walking; (3) there is no ability to swim; ( 4) Larger quality. (3) Contents of the invention [0003] The object of the present invention is to provide a posture-changing reversible amphibious multi-legged robot with compact struc...
