The ultra coaster is a motion simulator that puts the rider in the middle of a fast paced roller coaster ride.  Other coaster simulators usually have video taped screens with static roller coaster rides that were pre-programmed to follow the video.  The ultra coaster features a Head Mounted Display for viewing the coaster in action.  Not only does the rider have a view forward, but also they can look over the edge and watch the ground pass by.  This new dynamic adds a sense of reality to the experience.  The ultra coaster is not preprogrammed but uses the actual physics of the track itself to determine the movement of the simulator.  The simulator can duck and surge as it follows along the track.  The prototype of the ultra coaster was presented at IAAPA 2000 in the Ronbotics booth.  The next generation of ultra coaster will feature a fiberglass seat with overhead restraint.  The rider will be able to choose from one of six tracks to experience.
