The MPI CyberMotion Simulator was developed at the Max Planck Institute for Biological Cybernetics as a novel alternative to traditional motion simulators. For the Max Planck Institute for Biological Cybernetics, the robot has been customized for use in basic and applied research by outfitting it with a seat in an enclosed cabin with a curved projection screen. The entire assembly is positioned on a linear track with a range of almost 10 m. The eight degrees of freedom (axes) of the simulator are not coupled and therefore the motion envelope is extended compared to traditional Stewart platforms. Hence, the simulator can be used to move participants into positions that cannot be attained by a Stewart platform. For example, the enclosed cabin can be positioned above the vertically extended robot arm, such that participants can be rotated along the vertical axis indefinitely and differential thresholds in yaw can be determined.
In a different configuration of the robotic 6DoF motion platforms , participants can be positioned in any orientation in the enclosed cabin or the seat, even upside-down, to investigate the influence of gravity on perception. The cabin is equipped with a stereo projection and mounting possibilities for force feedback haptic devices used for flight and driving simulation. The MPI CyberMotion Simulator can be programmed to move participants passively along predefined trajectories. It also allows participants to have complete active control over their movements through the use of various control devices (e.g. steering wheel and pedals). In this mode of operation, the MPI CyberMotion Simulator can be used to simulate the behavior of virtual vehicles such as cars, airplanes, and helicopters.
These setup provides visual, auditory and inertial stimuli and allows to measure physiological parameters, such as eye movements and functional brain imaging (using near-infrared spectroscopy). With these capabilities, several open questions in human vestibular neuroscience (e.g., tilt-translation resolution) and optimized motion cueing algorithms for superior simulator designs can be addressed.

The mission of the Movememnt to Health (M2H) laboratory at the University of Montpellier is the identification of movement signatures of health. These markers (physiological, neuromuscular, segmental, sensori-motor, etc.) when taken together, constitute a behavioural map, allowing the early detection of potentially risky behaviours (falls for instance), and predictions about forthcoming perceptual or motor deficits (e.g., loss of autonomy with age, etc.). They reveal accurate information about the state of the sensori-motor system before, during, or after chronic or sudden brain / spinal cord injuries (hemiplegia, paraplegia, tetraplegia). They contribute to increase the precision of clinical diagnoses and provide guidelines for accelerating rehabilitation. These hallmarks allow the detection of risky behaviours but also of sensori-motor talents, skill level, expert performance, and general efficiency.
