Abstract

The invention discloses an omni-directional mobile platform capable of implementing synchronous steering. The omni-directional mobile platform comprises a mobile platform frame, a steering mechanism, a steering driving device and driving wheels. The steering mechanism comprises a spiral gear transmission system, a bevel gear transmission system, a gear rack transmission system and a sliding rail assembly. The sliding rail assembly comprises a guide rail and a sliding block. The steering driving device comprises a stepping motor and a speed reducer. Each driving wheel comprises a wheel leg, a servo motor, a speed reducer and a wheel body. The mobile platform is of a wheel type structure and is provided with the four driving wheels, the steering driving device controls the driving wheels to perform steering through the steering mechanism, and the driving wheels drive the mobile platform to move. The four driving wheels are controlled through the stepping motor to perform synchronous steering and are controlled simply, motions are accurate, the steering mechanism is installed in the mobile platform, the servo motor and the speed reduce are installed in the driving wheel leg, high-speed high-precision omni-directional movement is implemented, and the omni-directional mobile platform has the advantages of being high in transmission efficiency, compact in structure and accurate in positioning and the like.

Description

technical field [0001] The invention relates to the technical field of intelligent robots, in particular to an omnidirectional mobile platform capable of synchronous steering. Background technique [0002] With the rapid development of science and technology, all-round mobile technology has attracted widespread attention, and more and more occasions require flexible transportation equipment, such as automatic transport vehicles in factories, luggage delivery vehicles in airports, and automatic wheelchairs for the disabled. etc. require more flexible transport equipment. Omni-directional movement refers to the movement of three degrees of freedom, front and rear, left and right, and self-rotation on a plane. Because cars in daily life do not have the degree of freedom of self-rotation, they do not move in all directions. Parking on the side of the car is relatively difficult. trouble. [0003] Traditional omni-directional wheels generally include the following types of omni...
