Abstract

The invention discloses a rim-separable wheel diameter variable mobile obstacle crossing robot, which comprises a machine body; one passive wheel expanding device is arranged at each of left and right sides of a rectangular machine box; every passive wheel expanding device comprises a driving motor, and an output shaft of the driving motor is fixedly connected with one end of a rotating spindle; the other end of the rotating spindle is rotationally connected with the middle of a chute ring base; an inner spoke is fixed in the rotating spindle, and three first connecting arms are arranged on the inner spoke; three second connecting arms are arranged on the chute ring base, a chute is arranged in the middle of every second connecting arm and arranged along the radial direction of the chute ring base; a driving unit is arranged between every first connecting arm and the second connecting arm. The device can equivalently realize the leg type movement function, and has high-speed movement performance and effective obstacle crossing ability.

Description

technical field [0001] The invention relates to a mobile robot, in particular to a mobile obstacle-surpassing robot with detachable wheel rims and changeable wheel diameters. Background technique [0002] In recent years, the demand for mobile obstacle-crossing robots has gradually increased in fields such as emergency rescue and disaster relief, military reconnaissance and attack, aerospace exploration, underwater underground pipeline detection, and people's livelihood services. At present, traditional mobile obstacle-crossing robots are divided into two types: wheeled and legged. Among them, wheeled mobile obstacle-crossing robots are mostly used in flat ground environments and have poor obstacle-crossing capabilities; legged mobile obstacle-crossing robots have complex structures and are difficult to control. Facing the changing working environment, traditional mobile obstacle-surpassing robots can no longer meet the operating needs of the above-mentioned application fie...
