Robot device capable of walking stably

Abstract

The invention discloses a robot device capable of walking stably. The robot device capable of walking stably consists of a support frame, a motor, a rotation shaft, a plummer block set, a weight set, a cam set and leg parts; the cam set comprises four cams, and every two cams form a group; and each group of the cams which are distributed at 180 degrees are fixedly connected to the rotation shaft. The motor drives the cam set on the rotation shaft to rotate and the four leg parts to move; compared with the prior art, the robot device has the advantages that all the leg parts can move by controlling one motor, so that the problems about the coordination of the motor and the initial state are not involved; therefore, the robot device is convenient to control; and the robot device can quickly move and is high in movement accuracy, high in stability, simple and compact in structure, strong in operability, and suitable for stable and quick movement occasions and moves safely and reliably.

Description

technical field [0001] The invention relates to the field of robots, in particular to a stable walking robot device. Background technique [0002] Robots can replace humans to complete many tasks, especially those in extremely harsh environments or boring and repetitive tasks, so they have become a research hotspot in recent decades. Walking robots, especially humanoid walking robots, are in contact with the ground in a limited area when walking, so they are more suitable for some specific occasions. For example, picking fruits in the field does not require continuous rolling, so it does much less damage to crops than rolling robots, so it has broad application prospects. [0003] Currently common walking robots generally have multiple joints, and each joint is driven independently. For example, the Chinese invention patent document CN101229826A discloses a lower limb mechanism of a 10-degree-of-freedom biped robot, which rationally arranges the position of the motor and o...

AI Technical Summary

Problems solved by technology

For example, the Chinese invention patent document CN1883994A discloses an artificial leg of an anthropomorphic biped robot. Because the height of the leg from the ground is improved, the stability and high efficiency of walking are enhanced. However, since a motor is installed on each leg, it still involves to multivariate coordination and initial state issues, thus increasing the complexity of the robot and reducing its practicability
