Quadruped robot body having flexible buffer structure and quadruped robot
A quadruped robot body having a flexible buffer structure includes a housing having an accommodating cavity, a buffer connection portion capable of connecting to a fixed end of a joint unit being provided at at least one position on the housing. The buffer connection portion is provided with a connection hole for fixedly connecting to the joint unit. One or more strip-shaped holes are provided in a region where the buffer connection portion connects to the housing. Further disclosed is a quadruped robot. The strip-shaped hole is provided on the buffer connection portion, and under the action of an external force, the strip-shaped hole can deform slightly to generate a slight displacement between the hole wall and a surrounding region, thus achieving buffering of the external force. The present invention features a simple structure, low manufacturing costs, no need to reserve an additional mounting space, and a compact structure.
