The goal of the MOTU project is a mechatronic system composed of four sub systems:
Modular robotic prostheses with knee and ankle joints that can be controlled ether independently or in a synergic mode.
A wearable sensory apparatus will be used to record kinematic and kinetic information from the user. Multimodal data fusion will be used to decode motor intentions of the user, commanding natural and fluent movement to the prosthesis. Advanced algorithms will be able to detect perturbations in the usual gait pattern allowing the prosthetic limb to timely react and mitigate the possible risk of fall.
A network of vibrotactile elements will provide the amputees with an augmented feedback about their interaction with the robotic artefact.
A smart socket, designed to optimize force/pressure distribution on the stump and to compensate tissue volume fluctuations will be developed starting from a 3D scan of the stump.
MOTU project has the ambition to improve the state of the art of lower-limb robot prostheses by addressing four levels of efficiency:
- Amputee’s physical efficiency: MOTU prostheses have the ambition to reduce the physical effort spent for the locomotion-related activities.
- Amputee’s cognitive efficiency: by means of intuitive control algorithms MOTU prostheses aim at reducing the mental effort caused by the use of a prosthetic artefact.
- Energetic efficiency of the active components in order to guarantee extended use of the prosthetic device.
- Overalll comfort and acceptability of the prosthesis.
