A robotic spine exoskeleton based on linear electric actuators for spinal deformity correction

This paper presents a conceptual design of a robotic exoskeleton for active correction of spinal deformities. Unlike existing support-based systems, the proposed approach is correction-oriented and uses a multi-segment structure with linear electric actuators. A comparative analysis of actuation systems was conducted, and the FOCOTECK LA14C actuator was selected for wearable application. The exoskeleton is designed as a vest-based system with actuators mounted via articulated joints to improve kinematic compatibility. A CAD model was developed to evaluate the feasibility of the design. Future work will include simulation and experimental validation using a 3D-printed prototype
