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.
Agreed! I did get running on an old Vista box recently.
@jstarne1 I believe to move a 3 wheeled omni vehicle sideways 2 wheels turn at half power in one direction and the 3rd wheel turns at full power in the opposite direction. 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.
OH now you got me going, I have to get me some of these wheels and make a new bot so I can play with this.
Once I have the two L298N in the body I will go from there.
Is there a STL for the spacer available to download?
@RZ90208 , I have two more Rovio bots if you want one lol
How much? I am interested if you want to sell one.
