The robot uses a “simple switch as a sensor and stands on only two wheels with inverted pendulum mechanism. When the robot is going to fall the motor starts and moves the robot to the direction it is going to fall, so the motor torque about the center of gravity that is higher than the motor makes the robot balanced.” Check out this video to see it in action.

The maker helpfully put up a tutorial in case you’re inspired to make one of your own! Although I’m not sure why you’d do that, other than to mess with your cat or something.

A.M.P. stands for “Automated Musical Personality”. That’s because the wheeled robot can follow you around and play your tunes wherever you go. When set to tracking mode, the robot will even keep tabs on your location and keep the speakers facing you at all times. The self-balancing 29-inch tall robot rolls along courtesy of a piezoelectronic gyroscope which keeps it from tipping over on its narrow 2-wheel base. There’s also an obstacle avoidance system to keep A.M.P. from bumping into walls or tumbling down the stairs.

As the ‘bot moves around the room, it’ll “dance” (more like wobble) to the tunes on your connected MP3 player, keeping with the beat – with a bunch of synchronized LEDs blinking all the while. A built in 12-watt amp and a set of three speakers pump out the music. You’ll be able to control the audio mix and a variety of sound effects by interacting with A.M.P.bot’s touch-sensitive mixing pad “hands”.

The A.M.P.Bot will be coming to the States courtesy of Hasbro’s Tiger Electronics this October (it’s available from SegaToys in Japan). Expect it to retail for about $500.

The Uno is a self-balancing motorcycle that uses a pair of gyroscopes to constantly keep its rider upright.

Designed by 18-year old inventor Ben J. Poss Gulak (and built with the help of a team of bike builders and engineers), the 120-pound motorcycle is so easy to ride, its only control is a single on-off switch. To ride forward, lean forward, to reverse, simply lean back. The degree to which you lean increases or decreases your velocity. By using a pair of wheels, the bike can also make turns based on your side-to-side movements.

The one-of-a-kind motorcycle was recently demonstrated at the 2008 National Motorcycle Show in Toronto, Canada. Its current whereabouts are unknown, but I’m pretty sure you’ll recognize it if you see it coming down the road.
