This technology enables intuitive 3D motion control by aligning the mechanical structures of master and slave devices through a continuum elastic body, cylinders, and a wire-based actuation and encoder feedback mechanism.
Conventional joystick-based surgical robot master devices require a high level of proficiency to control the multi-jointed 3D movements of slave devices. Furthermore, the absence of a wire restoration system often leads to reduced operational precision, while the addition of separate restoration devices increases structural complexity and operational force.
This technology features a master/slave device configuration based on a longitudinally symmetric wire structure for elastic bodies. By winding a pair of wires in opposite directions around a single wheel to maintain constant tension, it provides a mechanical mechanism that precisely detects and reproduces 3D bending motions without the need for separate restoration devices. Applicable to surgical robots, remote operation, and medical automation, it enhances operational intuitiveness by accurately reproducing 3D movements without additional restoration hardware.
