Problems solved by technology

[0007] 1. When the power system is working, it needs to be connected to the fuel tank through the oil pipe. The length of the oil pipe limits the range of the robot’s activities.
[0008] 2. Gear pumps, solenoid valves and other components consume too much energy, which reduces the utilization rate of energy
[0010] 4. The mechanical range of motion of the piston is restricted by the space of the hydraulic cylinder cavity, which limits the range of motion of the robot's legs

Abstract

The invention discloses a frog jump robot. A motor is used as a power element; devices such as an overrunning clutch, a gear toothed belt and the like are used as transmission mechanisms; a slide block can move on a guide rail under the drive of the motor through the transmission devices; and double legs of the robot stretch or retract under the drive of the slide block so as to finish jump motion. After the robot jumps, the double legs immediately retract to perform air posture adjustment, and the double legs are fully retracted by using self gravity potential and kinetic energy at the monument of landing to perform posture adjustment again. The energy utilization rate of the power element is improved, reclamation and reutilization of energy during jumping are realized, the flexibility of the robot is increased, and the jumping capability of the robot is promoted.

Description

technical field [0001] The invention relates to a robot device, in particular to a jumpable robot device. Background technique [0002] With the continuous development of robot technology, in the face of harsh environments and complex terrain, using the robot's bouncing function to enhance its ability to adapt to terrain and autonomous movement is a robot technology that has developed rapidly in recent years. Robots with bouncing performance are still in the research stage in the world, and only a few colleges and universities in China are conducting related research. Since the development of such robots is very difficult, many key technologies involved are highly confidential, so there is very little public information. [0003] Internationally, the earliest bouncing robot was successfully developed by Raibert in the Robotics Laboratory of the Massachusetts Institute of Technology in 1980. The robot belongs to the continuous jumping mechanism. Raibert analyzed the take-off...
