Novel Mechatronics-Twin Framework based on Stewart Platform
Within the EU H2020 project SocketSense, a novel mechatronics-twin framework has been developed to integrate advanced biomechanical modeling and simulation capabilities with the support for physical testing by a Stewart Platform for effective exploration of operational behaviours of prosthetic sockets with amputees.
The use of a prosthetic device aims to restore the ambulation and self-esteem of an amputee as much as possible. The major components of a trans-femoral prosthesis include socket, suspension, knee joint, pylon and feet. Among these components, the socket serves as the interface between the residual limb and the prosthesis. It must protect the residual limb and appropriately transmit the forces associated with standing and ambulation.
The mechatronics-twin frame-work serves as an analytical replica for revealing complex operational interplay between the amputee, the prosthetic device and the prosthetic socket, allowing both virtual and physical replications of the device. The virtual replication is supported by Bio-mechanical modelling and simulation, and Finite Element Analysis. The physical replication is supported by 3-D printing and prototyping, and physical testing by Stewart platform.
