On the design and validation of a parallel robot for lower limb rehabilitation
Keywords:
parallel robot, robotic rehabilitation for lower limb, robot design, robotic system testing, finite element analysisAbstract
This paper focuses on the enhancement of the design of a parallel robotic system for lower limb rehabilitation for bedridden patients following a stroke. The robotic system consists of two parallel robotic modules, each one targeting specific patient’s joints, namely the hip-knee module and the ankle module. A FEA has been performed on the main elements of the robot to identify the most suitable profile to be used within the final design of the mechanism. An evaluation of the robotic system's user acceptability was also undertaken within laboratory tests conducted with healthy subjects to determine the overall level of satisfaction regarding the robot's performance.
