Steering device for mobile robots

Steering system for four-wheel drive using belt-connected drive and steering linkages

This technology is a four-wheel drive and steering system utilizing two motors (left and right). By using belts, bevel gears, and steering linkages, it reduces the number of motors required while enabling synchronized driving and steering for both front and rear wheels.

Conventional four-wheel robots typically place a motor at each wheel, which complicates control, increases manufacturing costs, and adds structural complexity due to link-based steering mechanisms.

This technology connects the front and rear drive units with a belt to transmit power from a single drive motor to all wheels, and implements a mechanical structure that controls left and right steering through a combination of spur gears and bevel gears connected to a steering motor.

Key Features:

• A pair of front-wheel drive units located at the front of the robot to drive and steer the front wheels
• A pair of rear-wheel drive units located at the rear of the robot to drive and steer the rear wheels
• A belt equipped with multiple gear teeth that connects the front and rear drive units to transmit driving force
• A base frame that supports the front and rear drive units, steering linkages, spur gears, bevel gears, steering motor, and drive motor
