Motion devices form the heart of any vestibular research lab. Here are videos of three of the devices in the Jenks Vestibular Physiology Laboratory.
The main motion for this device is to tilt, but the device can simultaneously translate radially and is also equipped with a degree of freedom that provides head on neck roll tilts (passive or active).

The Moog platform can simultaneously rotate, tilt and translate in all of the possible six degrees of freedom of motion.
