Robot

Obstacle-surmounting robot with variable height via inclined rotation axes and driving units of different lengths

This technology features driving modules on both sides of the robot body, each equipped with first and second driving units of different lengths that rotate around an inclined axis. This allows the robot to adjust its driving height by switching and rotating the driving units, maintaining its center of gravity while navigating obstacles.

Conventional wheeled robots faced structural limitations where increasing wheel radius to overcome obstacles raised the center of gravity, thereby reducing driving stability.

This technology overcomes obstacles without raising the center of gravity by tilting the rotation axis downward and using a drive motor to rotate driving units of varying lengths, effectively changing the ground contact position. Applicable to exterior wall cleaning robots and outdoor patrol robots, it provides high-performance obstacle traversal while maintaining stability.

Key Features:

• Driving modules provided on the left and right sides of a body with a defined volume
• A rotating member rotatably connected to the body by a rotation axis and coupled to said axis
• A first driving unit extending from one side of the rotating member at a first inclination angle in a direction away from the rotation axis
• A second driving unit extending from one side of the rotating member at a second inclination angle in a direction away from the rotation axis
