The device that is the subject of this investigation is a robotic assistance module for driving a semi-autonomous electric wheelchair. This module is designed to accessorize the electric wheelchair to improve the safety conditions when driving an electric wheelchair, which on the one hand reduces the accident rate of wheelchair and on the other hand and facilitates the access to the wheelchair to people who cannot claim it without the use of a safety device of this type. The robotic assistance module is programmed to detect positive and negative obstacles.

This study "SWADAPT3" follows "SWADAPT1" and "SWADAPT2" with patients with Neurological Disorders, Regular Drivers of Electric Wheelchairs, in the same conditions:

Each patient included tested a wheelchair equipped with a collision avoidance assistance module in 2 conditions, assistance activated or not. This evaluation was carried out in 3 standardized test circuits of increasing difficulty, one week apart. At each session, the patient performed the circuit 6 times, including 3 with activated assistance, in a random order established upstream.

Inclusion Criteria:

• Aged over 18,
• Having read the information note and freely consented to participate in the study,
• Suffering from neurological disorders such as cerebro-lesion or neuro-degeneration,
• Having benefited from an electric wheelchair prescription and/or learning to drive,
• The physical measurements (weight, height) are compatible with the use of the electric wheelchair chosen for the development of the robotics assistance module.

Exclusion Criteria:

• Understanding difficulties preventing the realization of the protocol,
• Motor disorders of the upper limb requiring additional driving technical assistance,
• Patient who has expressed difficulties impacting their internal and/or external driving safety,
• Pregnant, parturient or breastfeeding women,
• A person deprived of liberty by a judicial or administrative decision, persons under psychiatric care or admitted to a health or social institution for purposes other than research,
• Minors,
• a person in an emergency situation, unable to express his prior consent.

To minimize bias, this study will be randomized and conducted in single blind. The patient will not be aware of the activation or not of the assistance module placed on the electric wheelchair. Indeed, the investigative team will be in charge of the activation of the robotic module.
