Jumping mechanism with adjustable jump-up angle for wheeled hopping robot

Abstract

The invention discloses a jumping mechanism with an adjustable jump-up angle for a wheeled hopping robot, and belongs to the technical field of robots. The jumping mechanism internally comprises two cylinder fixed frames; fixed frame outer side plates are fixedly connected with fixed frame inner side plates by fixed frame plain shafts, double-acting cylinders are fixedly fastened among the fixed frame inner side plates and the fixed frame outer side plates by locks, and cylinder foot pads are mounted on lower portions of cylinder piston rods; movable frame inner side plates and movable frame outer side plates are fixedly connected with one another by movable frame plain shafts to form movable frames; and a corresponding control motor runs, so that the movable frames can drive miniature lead screws to rotate, and distances among light wheels connected with the movable frames can be adjusted. The jumping mechanism has the advantages that miniature actuators, actuator cranks, transmission rods and the double-acting cylinders form double-rocker mechanisms, the jump-up angle of the mechanism can be adjusted by the cylinders under the control of the actuators, and the cylinders are matched with decompressed high-pressure air, so that efficient jumping effects of the cylinders under the control of electromagnetic valves are realized.

Description

Technical field: [0001] The invention relates to a bouncing mechanism of a wheeled jumping robot with an adjustable take-off angle, which belongs to the technical field of robots. Background technique: [0002] With the continuous expansion of the application range of robots, the environment faced by robots is becoming more and more harsh. Such as archaeological exploration, interstellar exploration, military reconnaissance and anti-terrorism activities require robots to have strong autonomous movement capabilities and survivability. The wheeled jumping robot can jump over obstacles several times or even dozens of times its own size, and has a large range of motion. The suddenness and explosiveness of the bouncing motion help the robot avoid danger and make it have a strong survivability. [0003] The bouncing mechanism is the key to determine the performance of the jumping robot, so whether an efficient and feasible bouncing mechanism can be designed is the key to the succ...
