A group of engineering students at San Jose University have cooked up an ambitious senior project. Max Ratner, Henry Li and Andrew Parmar came up with the concept of applying an omnidirectional drive system to the motorcycle world during a brainstorming session a little over a year ago. Inspired by the self-balancing technology found in the Segway personal transport and a balancing robot developed in Tokyo, the trio of mechanical engineering students settled on applying the same principles to a motorcycle device as a proof of concept. The idea went through a number of evolutions before settling on the design you see here with two massive spheres enclosed in a tube cage.

The spheres are controlled via three electric motors that provide small inputs to keep the rig upright via some clever software. The result is a machine with a zero turning radius that anyone one can ride regardless of skill level or physical handicap. The bike can immediately change direction to move perpendicular to the previous path of travel, but Ratner, Li and Parmar want to make it clear that they aren't out to revolutionize the way vehicles travel.

"This is more of a proof of concept," Parmar said. "We want to show that something like this is actually possible."

Even so, the team sees plenty of advantages to spherical drive, including computer-aided crash avoidance and parking. The tech may also have applications outside of the automotive sector, including use in fork lifts where speed and foul weather grip aren't issues and the design's superior maneuverability could be a major asset.

The team has received substantial help from a handful of local sponsors, including Wolfe Engineering. The company fabricated the frame for the first prototype based on the team's designs and a second sponsor, Animatics, supplied the vehicle's motors as well. With the physical hardware in place, the team needs only to finish the programming to show off their creation balancing on its own and operating on a smooth surface. There are certainly disadvantages to the design, and the team seems aware of some of the largest, but for right now, it's simply impressive to see a group of college guys crank out a prototype of this caliber.

"We're taking it one step at a time," Ratner said. "Road applications are farther down the road and will require further R&D."

      Shouldn't Audi be sponsoring them? Lest we forget the Original RSQ concept from I, Robot. http://www.supercars.net/carpics/2945/2004_Audi_RSQConcept3.jpg

      The bike will stay up in a high speed turn but will the passenger or rider stay on without the tilt???

      Anyone else see a problem with the spheres having to float in a cage rather than being fixed to an axle like wheels are?
        • 2 Years Ago
        its floating because you are born in 1992, and you do not study engineering. :D an axle limits rotation to a wheel to be in only one axis. this drive system can rotate in any direction thus any axis, therefore it has many axles.

      Hmmm. Keep up on it. I'm not quite impressed yet, but it's a great experiment.

      didnt the Audi in I-Robot have wheels like this ?

      This is how engineering goes... you make stuffs that others think stupid, and then voila, invent something useful and new.... Everyone during Wrights brothers' time think the siblings nut too

      I love it a bike with balls

      it's SJSU (San Jose STATE University). You're making it sound too elite by excluding State. I'm from the San Jose area, and we'd (collectively, as a region) prefer you mention that it's a state university....intelligent **** goes down in the Silicon Valley. DEUCES.

      I want to see the omni-directional tread pattern on those "wheels"!

      wayne enterprises already beat you to the punch, a little known military vehicle from a defunct contract, nicknamed the "Bat Pod" after witnesses claimed they saw batman driving one.
      • 2 Years Ago
      Not on your life, not getting close to that thing.
      • 2 Years Ago
      Yes, works great when the motors support the weight of just the ball, but when the ball has to support the weight of the bike, when supported only at three small points, will deflect to the point where the ball is rubbing on the support cage and can't move worth a dammm. What kind of engineers are these guys???
