Abstract

The invention relates to the field of walking robots, in particular to a multi-connecting rod bionic mechanical leg and a crawling robot. The multi-connecting rod bionic mechanical leg comprises a matrix, a driving part, a rocking rod, a first connecting rod, an intermediate four-connecting rod mechanism and an output four-connecting rod mechanism; the driving part comprises a steering engine anda steering engine plate which is mounted on an output shaft of the steering engine; the output four-connecting rod mechanism 6 is hinged to two rods of the intermediate four-connecting rod mechanism 5; the intermediate four-connecting rod mechanism drives the output four-connecting rod mechanism 6 to work; an output rod of the output four-connecting rod mechanism 6 extends out to achieve the movement in a specified trajectory. The matrix, the steering engine plate, the rocking rod and the first connecting rod form a crank-rocker mechanism; the matrix is a fixed machine frame; the steering engine plate is a crank; the intermediate four-connecting rod mechanism consists of the rocking rod, the first connecting rod, a second connecting rod and a folding plate; the output four-connecting rod mechanism consists of a section of the rocking rod, the folding plate, a third connecting rod and an output rod.

Description

technical field [0001] The invention relates to the field of walking robots, in particular to a multi-link bionic mechanical leg and a crawling robot. Background technique [0002] Bionic robots refer to robots that imitate living things and work on biological characteristics. The specific action is flexible and adapts to the environment of multiple working conditions. However, the existing mechanism is complex and the force on the joints is uneven. [0003] The State Intellectual Property Office published the publication number CN105818881A on 2016.08.03, and the patent name is the link mechanism bionic mechanical leg and its quadruped robot, including the calf rod, the main driving part of the thigh for driving the calf rod to lift the leg and the driving part for driving the leg rod. The thigh auxiliary driving part of the calf rod for stepping also includes the power output end hinged to the main driving part of the thigh, the power output end of the auxiliary driving p...
