Developed by the interactive robotics unit of CEA LIST, based in Paris, EMY (Enhancing MobilitY) is a full-body exoskeleton designed to help quadriplegic people walk again.
The original technologies implemented in EMY were developed during the last 10 years by a team of 20 researchers and engineers from various research domains, including force-feedback teleoperation robots for nuclear facilities and haptic devices for virtual reality.
The particular design of EMY’s limbs, especially the arms (ABLE®), allows them to be used as haptic devices. The required high transparency is achieved using a patented, streamlined, mechanical transmission (screw-cable system) that minimizes friction and inertia. It also ensures that the current in the motor is an accurate image of the joint torque, so there is no need for a torque/force sensor. This is not only simple and reliable, but also energy-efficient and cost-effective.
