Aramis consists of two symmetrical exoskeletons each having 5 active and 2 passive degrees of freedom to allow precise adjustment to different patients.
The patient sits on an adjustable chair that is placed centrally between the two exoskeletons he wears. The kinematic chain of each exoskeleton has been reproduced from the natural movements of the human arm.
Each exoskeleton is master and slave of the other and can record the movement of the healthy limb and replicate it on the plegic limb. The rehabilitation programme is established by the rehabilitator. The system allows sessions to be customised or preloaded rehabilitation programmes and sessions to be used.
The patient, having donned the exoskeletons within a maximum of 5 minutes, begins the session in total safety with minimal supervision by the therapist. The operating modes of Aramis include:
- the possibility of recording three-dimensional movement in space with the healthy limb and replicating it asynchronously on the plegic limb;
- the possibility of recording the three-dimensional movement in space with the healthy limb and replicating it in synchrony on both exoskeletons;
- the possibility of the robot’s intervention in active-assisted mode should the patient fail to complete the movement of its previous recording.
