Universal Islands of Adventure - Wizarding World of Harry Potter - Harry Potter and the Forbidden Journey
While Pat and Jeff were on it, the ride briefly stopped a couple of times. That made the emergency lights come on which gave me a great opportunity to get a clear shot of the ride vehicle. Each four-seater was attached to a robotic arm which can move in almost any direction. Here's a short video I found online that shows how similar technology was used at an Innoventions exhibit at Epcot (except there the base of the arm was stationary; here it travels along a track through the ride building). In this ride, you traveled through three-dimensional sets with animatronics (dragons, spiders, the whomping willow), and you also seamlessly interacted with movie screens, like a motion simulator. The filmed sequences featured members of the original movie cast.
Here's a great video I found that shows the whole ride.
