Self Balancing Bicycle Demo

Professor Andy Ruina is a mechanical engineer and cyclist and also a professor at Cornell University. He spent over 25 years figuring out why a bicycle can't balance on its own. He's finally figured out why it happens and also has a solution. When we are riding a bicycle, we think we are riding in a straight line, however, when the CG of cycle falls to the left, we counter it by steering to the left and when it falls to the right, we steer to the right to make sure that the CG of cycle stays right in the middle.

Paper: A Bicycle Can Be Self-Stable Without Gyroscopic or Caster Effects

Quite interesting. I had been following this for quite some time.
While on cycling here is some news:

The article in the first post mentions that the cycle they've developed may not be very useful for the regular bicycling as the weight is distributed over the front wheel.

@ Biggie: Actually cannot imagine that people can spend 25 years for this thing.

@Bioramani Sir: Giant is a very popular brands as far as mountain bikes are concerned. Another is Gary Fisher. We need to know more technologies of them too. 😀
