Sure, so our turret is 270 degrees. We chose to go only 270 primarily because with the double intakes the driver is trained to keep the front of the robot towards the Hub and use the correct intake to pick up Cargo such that the turret is always locked on. This worked well in competition and we never felt like we needed more degrees of rotation.
It took us awhile to figure out the energy chain routing and it still isn’t perfect. All wires are terminated at the entrance and exit so if a link in the chain breaks (which happened relatively frequently) it can be swapped out quickly. The energy chain is basically pinned at both ends with a bolt and then a passive tensioner takes up the slack when the turret is facing forward to keep it out of the way of the climber and from snagging on other robots. The problem was if the energy chain broke at all during a match we would have a hard time climbing as the climber arms would have to push the energy chain partially out of the way as they deployed adding a few seconds to our climb. In the future I would try to incorporate more clearance where the energy chain mounts to the front of the shooter so it would be easier to access the connectors for the shooter motors and so a more robust mount could be created.
