Our team of inventors attempts to prototype a car that utilizes biofeedback sensors to restrict a cars performance as its driver's agitation level increases. Joe and Zoz will use cutting edge biofeedback and mind control technologies as the brains of the prototypes while Terry and Mike retrofit the test cars for an extreme test to prove the concept: a demolition derby where road rage is inevitable.

The prototype team looks into the future of gaming -- and giant, boxing robots are what they see. Joe and Zoz utilize a technology called optical glyph tracking to allow the robots to register and mimic their human counterparts' boxing movements while Mike is charged with dressing the metallic skeletons and Terry with building the metal beasts themselves. And then it's into the boxing ring for a metallic monster slugfest!

The boys take on the challenge of building a car that will beat traffic by rising up -- and driving over it. And as an added bonus, the lift allows the vehicle to find parking like nothing else on wheels. The key to this build is a set of amazing wheels that can move in all directions without actually turning.

Inspired by the "legs" of an innovative robot called RHex, the prototypers decide to use this basic design with its synchronized alternating tripod gait and build it BIG! What first appears as a simple upscaling project becomes a real challenge when the team discovers that size can change everything.

No water theme park is complete without a long run on a water slide, but what do you do when you don't have the room in your backyard? Let the the laws of physics give you a ride! In what may be their most massive build, the team puts together an amazing, fun-filled "slide-in-a-ring" and then turns on the hose for some aquatic fun.
