Thanks, the accuracy of the propulsion type launch is incomparable to that of a friction design.

Our center of gravity is about 2" towards the back of the robot(omni-wheel side), it works great because we can change it based on the position of the launching system.

That is actually not an air accumulator on the front, our air accum. is mounted on the underside of the robot. In the front is an 18" air cylinder to push the robot up to get over the bridge, the omni's are lifted into the air and then we drive forward to get the wheels and push down the bridge.

Our loading system was not mounted when we filmed the video but the plan is to load from the ball return slot, we will be able to drive right up to the slot and put balls into a hopper. This is possible for our robot because we don't intend on crossing the bridge except for the one initial time, the rest of the shots will be made from half-court.
