Problems solved by technology

Generally speaking, wheeled travel is suitable for better road conditions, with fast speed but low obstacle-crossing ability
The existing wheeled ground mobile robots, such as the rocker type, have a certain ability to overcome obstacles, but the stability and shock resistance of the body are insufficient, and cannot meet the special missions that require stable travel.
Existing wheeled robots, such as bouncing robots, have outstanding ability to overcome obstacles, but they are also limited by the lack of stability of the body during the process of travel, and the complex structure and poor fault tolerance
Existing wheeled robots, such as the multi-link independent suspension type, have a good shock absorption function, but the structure is complex, and the ability to overcome obstacles is not high. Once a rollover occurs, the robot will lose the ability to continue to perform tasks

Abstract

The invention discloses a wheeled mobile robot. The robot comprises a frame, suspension support devices, annular wheel bodies, drive motors and gears. The inner annular wall of an annular wheel body is provided with an inner gear ring. The drive motors are placed on the suspension support devices. The gears are connected with the output ends of the drive motors. The suspension support devices are suspended at the inner ring of the annular wheel bodies, and the gears are meshed with the inner gear ring. The suspension support devices are installed on two side portions of the front and rear ends of the frame. The wheeled mobile robot possesses the bidirectional suspension function, and has the advantages of being high in operation efficiency, strong in obstacle crossing capability, and convenient to assemble, dissemble and maintain.

Description

technical field [0001] The invention mainly relates to the field of ground mobile robots, in particular to wheeled mobile robots. Background technique [0002] At present, the ground mobile robots developed worldwide mainly focus on wheeled, legged, tracked robots and some field robots with specific functions. Generally speaking, wheeled travel is suitable for better road conditions, with fast speed but low obstacle-crossing ability. Existing wheeled ground mobile robots, such as the rocker type, have a certain ability to overcome obstacles, but the stability and shock resistance of the vehicle body are insufficient, and cannot meet the special mission occasions that require stable travel. Existing wheeled robots, such as bouncing robots, have outstanding obstacle-surmounting capabilities, but are also limited by the lack of stability of the body during travel, complex structures, and poor fault tolerance. Existing wheeled robots, such as the multi-link independent suspens...
