Multi-jointed Robot

Multi-jointed Robot

This technology features multiple multi-jointed legs coupled to a main body, with friction pads at the base of each leg featuring grooves that provide anisotropic friction. Each leg consists of alternating joint units with a first joint axis and a second joint axis perpendicular to it. By aligning the grooves of the friction pads parallel to the connection direction, the robot mimics snake-like movement and enables multi-jointed walking functionality.

Wheeled robots are limited by road surface conditions, while conventional legged robots often struggle with mobility or maneuverability on rough terrain and suffer from reduced efficiency when utilizing multi-jointed structures.

This technology utilizes a hyper-redundant leg structure that mimics the biological movement of a snake, combined with anisotropic friction pads that induce varying levels of friction based on the direction of ground contact. By forming longitudinal grooves in the friction pads, the design minimizes interference during walking motions and enables terrain-adaptive maneuvering. Applicable to industrial robots and automation systems, this technology enhances robot mobility and adaptability in challenging terrains and environments.
