Mecha Madness
The things people do to  pick up chicks...

You're right, its made by some hobbyists who always dreamed of riding in the robots they played with as kids.

The thing has a 250cc engine and moves through a system of four pedals, movement is corrected by an onboard computer, and with two hands the pilot can manipulate two different types of guns that shoot cushiony air ball things. It moves at a rather disappointing 1.5 km per hour. On the right side is a 'Vulcan type' cannon and on the left is a 'Shotgun type'..both sides get six shots each. It's the only one currently in existence but its intended to show that robots like this can be made using existing technology… the makers hope that in the future there will be 'robot wars' (games).
