The invention discloses a multifunctional bionic jumping and walking robot. Only a jumping track and only jumping movement can be achieved by existing robots, the existing robots can only move on flat terrain and can not be adapted to the complicated terrain environment in the natural world. According to the multifunctional bionic jumping and walking robot, two fore limb bionic mechanisms are symmetrically arranged on the front portion of the trunk of the robot, two hind limb jumping mechanisms are symmetrically arranged on the rear portion of the trunk of the robot and are both connected with a spring locking and unlocking mechanism, the spring locking and unlocking mechanisms can drive and lock or unlock the hind limb jumping mechanisms, and each spring locking and unlocking mechanism comprises a main motor, a third straight gear, an input shaft, a fourth straight gear, a pawl, a clutch movable block, a clutch fixed block, a shifting fork driving motor, a second crank, a second connecting rod and a shifting fork. According to the multifunctional bionic jumping and walking robot, jumping angle adjustment, jumping height adjustment, continuous jumping and automatic resetting can be achieved, frog type jumping and kangaroo type jumping can also be achieved, and the multifunctional bionic jumping and walking robot can turn on a fixed position and walk so as to be adapted to the complicated environment.
