Abstract
A driving device of a robot includes at least one driving assembly and a fixing assembly that are arranged outside a base of the robot. The at least one driving assembly includes a motor, an omnidirectional wheel, a connection shaft used to connect an output shaft of the motor to the omnidirectional wheel, and a connection assembly used to connect the connection shaft to the motor and the omnidirectional wheel. The motor, the connection shaft and the omnidirectional wheel are arranged along a radial direction of the base, and the fixing assembly is used to fix the motor to the base of the robot.
Claims19
A driving device of a robot comprising at least one driving assembly and a fixing assembly that are arranged outside a base of the robot, wherein the at least one driving assembly comprises a motor, an omnidirectional wheel, a connection shaft configured to connect an output shaft of the motor to the omnidirectional wheel, and a connection assembly configured to connect the connection shaft to the motor and the omnidirectional wheel, the motor, the connection shaft and the omnidirectional wheel are arranged along a radial direction of the base, and the fixing assembly is configured to fix the motor to the base of the robot, wherein a lateral surface of the output shaft of the motor comprises a first external planar surface that defines a positioning hole, a hub of the omnidirectional wheel defines a mounting hole having an inner side surface that comprises a first inner planar surface, the connection shaft comprises a first end and a second end, the first end defines a receiving hole that allows the output shaft to be inserted thereinto and has an inner surface comprising a second inner planar surface, the second inner planar surface comprises a protrusion matching the positioning hole, and the second end has a lateral surface comprising a second external planar surface matching the first inner planar surface.
