Re: How much Bridge Space does your robot need?

We take up only 13"+ of bridge width as we cantilever the other 20" of our width, hanging off the center-of-field side of the bridge, extending most of our bot into the air well beyond the guide rail (which we do not grip). We are a six wheel "kitbot on steroids" size with severe weight concentration right forward. Our plan is to facilitate three bots on the bridge by allowing a pair of 34+" max width bots to drive right past us while we hold bridge down for them with us parked on side edge and overhanging toward center of field, just past tipping (toward them) point of the bridge. Since we can all three stay nearer the center of the bridge with this scheme, this makes balancing much easier and faster. We are thinking only 10-15 seconds for all three to balance -even with no practice.

We can tip the bridge and drive it end to end along the rail. We can balance it alone in a few seconds after our first wheel goes up. We can pre-tip the bridge downward and hold it there, allowing for our arriving alliance partners to just simply and accurately drive right up and balance (assuming they are not over 34.5" wide). We play defense and shoot returned balls the length of court, but shots go only where robot points (no aiming turret). We are still trying to get a ball pickup scheme working.

If we are partnered with wide bots in qualifying rounds, then we can go for the middle bridge coompertition points . Wide bot alliances will know not to pick us for the elimination round, In the elimination round we hope to be on an alliance with too good shooting offensive minded partners. Our 4-CIM drives lets us play decent defense and/or park at the return slot to fire balls back up the full length of the court - over any defender parked in front of it..

In Autonomous, we can get to the center bridge very fast and, since we have most of our weight up front we are going to win most tipping battles there to get those balls, After which we move over to our bridge bringing those two balls down on our way to the other side to play defense and be an up the court ball passer.

We think we will be a good alliance match fro the right capability partners.
