Errrr omnidirectional steering. You can go in any direction you want to with at least three of those wheels that are powered.

I know that but why was such a big deal made about them? is there anything special about how they were used?

It was used as a part of this revolutionary drive system

It is so important because it shows the Engineering Inspiration that FIRST is all about. It is something more then a tank or a box on wheels.

So what was up about the striking similarity between the Da Bears drive system and the secondary Technokats drive system?

Does my post belong in another thread?

Chewy: 'da Bears, team 247, did not have anything similar to Team 45's Ball Drive robot.

247 had 3 wheels (much like last year), and used 3 motors. The drills and a chiaphua with matched speed. Also, in each of the 3 they had an on-the-fly shifter. A fourth motor, which I believe was a globe, drove the rotation mechanism.

Basically put, on 247's bot, the wheels and motors all spun around to provide "omnidirectional" movement. In 45's secondary bot, everything stays stationary and the direction the ball is spun dictates it's movement. As probably stated in the other thread, the movement of the ball is based on how the two motors are moving. If you look at the ball picture, you can see how it has to axes of movement giving it omnidirectional movement from a standstill.

PM me if you would like a further explination of either system.

You can see two of 247's wheels (along with their suction system) in this picture:
