Hello All, I have a couple of these Rovio robots I made new batteries for. I think this old robot could have new life. Unlike most robots these guys have three omni wheels. That being said I don't even know where to start to make the robot chaff side to side so I am taking that off the list. I would be satisfied for now being able to left rotate, right rotate, forward and backward. The forward and backward only use the front wheels but rotation means all the wheels need to move in the same direction. I would like to gut this Rovio out and set it up to demonstrate the UV/IR QR code reading on the floor, forward and ceiling. 
It is a real shame that the company didn't provide support or continue production.
For the price at the time, and even today, there is a lot of bang for the buck in this product.
This is one of the robots at a cheap price that was true telepresence. I used it in a business that I worked at 150 miles away to do some support at.
the idea is omni movement is achieved through a sum of forces generated by each wheel.
So 2 wheels trying to rotate it Clockwise each at half power and the 3rd wheel trying to go cclockwise at full power should drive it sideways to the left.
Don't have one of these but that is how I see it working.
How much? I am interested if you want to sell one.
