Wheels
On wednesday David Anne and I put together the mecanum wheels with the bearings from last year's wheels inside. We measured the width of the bearings and the width of the spacers that were inside of the mecanum wheels and the bearings were 3mm short. To temporarily take care of the change in width we layered tape onto the plastic around the bearings. Since the bearings have two sides of plastic parts that could come loose, we decided to use three of the holes to hold the sides together with screws and bolts. The other three holes were used to hold the complete wheels together. We then noticed that the sprocket must be spaced apart from the wheel so that the chain won't hit the wheels.
