The system we built for the Central Institute for the Deaf at Washington University in St. Louis, seen here, featured several slip rings that passed power and data to and from the constantly moving machinery. Everything you see, with the exception of the high-torque Kollmorgen motor, was designed and built by us. 

Among other uses, Dr. David Dickman utilizes the system to view the firing of neurons within the humanely cradled animal model while it is in motion (nominal operation typically is slower than the demonstration mode depicted in the video).

We've built custom vestibular test systems that accommodate human and non-human primates as well as birds.
