Robotic exoskeletons for rehabilitation usually consider only references in the joint-space with cartesian parameters, like step length and foot clearance, as a consequence of the previous. This work solves the inverse kinematics problem through a meta-heuristic stochastic approach, placing step characteristics as the inputs of the problem, rather than the consequence of the joint kinematics and generating feasible joint trajectories to achieve the rehabilitation goal.

摘要

Robotic exoskeletons for rehabilitation usually consider only references in the joint-space with cartesian parameters, like step length and foot clearance, as a consequence of the previous. This work solves the inverse kinematics problem through a meta-heuristic stochastic approach, placing step characteristics as the inputs of the problem, rather than the consequence of the joint kinematics and generating feasible joint trajectories to achieve the rehabilitation goal.
