High-Rigidity Deployable Robotic Arm with Folding and Rolling Storage, and Mobile Robot Including the Same

This technology is a deployable robotic arm that utilizes multiple panels wound around a hub. By applying sliding and folding mechanisms, it minimizes volume through a rolling method during storage and achieves high structural rigidity upon deployment by forming a bent structure via shape-forming and shape-maintaining devices.

Existing deployable robotic arms have faced technical limitations where storage efficiency and rigidity are in conflict due to link joint play, weakened strength at folding lines, and thickness constraints inherent in rolling structures.

This technology proposes a method where panels with sliding and folding structures are stored by winding them around a hub. Upon deployment, a shape-forming device guides the panels into a bent structure, while a shape-maintaining device—comprising a spacing adjustment unit and a wire winding unit—ensures structural rigidity in the deployed state. This allows for both high storage efficiency and high rigidity. It serves as an innovative solution that overcomes the fundamental limitations of conventional robotic arms in fields requiring both portability and strength, such as space structures, disaster site exploration equipment, and mobile service robots.
