Multi-jointed mobile robot with curved sections and elastic damping structures for adapting to stair heights

This technology features a multi-jointed mobile robot that connects its body and arms using multiple link members, with curved sections and elastic damping structures formed on the underside of each, allowing it to adaptively navigate and traverse stair steps.

Conventional wheeled robots are efficient for travel on flat surfaces with uniform height, but they face structural limitations when effectively navigating uneven terrain such as stairs.

This technology incorporates repeating curved sections along the bottom of the housing and arms, utilizes elastic damping members, and controls relative positioning via rod-shaped connecting members to vary the contact surface. It can be applied to indoor delivery robots and building inspection robots, enabling smooth and stable movement even in environments with stairs and thresholds.

Key Features:

• A body providing a central structure with a housing, and arms provided on the left and right sides with frame sections
• A rod-shaped connecting member of a set length, rotatably connected to the body by a drive shaft
• A connecting member configured such that its other end is rotatably connected to the arm by a connecting shaft
• A drive member located in the housing and connected to the drive shaft, and a body curved section formed on the bottom surface
