Inside there are five kit compressors and four CIMs driving AM 6" mecanums through Banebots 12:1 planetary transmitions. All of the compressors are powered by one battery and the drive, elevation, and controller are powered by the other.

The issue is trying to run the compressors over an extended amount of time. We can fire about three shots at max pressure before the battery is drained. The other issue we didn't plan for was firing when our team scored, it is unpredictable at best and holding pressure for long periods of time means the compressors tend to be "topping off" constantly. Either getting a battery better suited to the job or having a setup where we can keep it plugged in most of the time are the options we are considering.

The other slight issue is that fact that the robot weighs about 275 lbs. It is taxing our drive as is and we are considering changing our gear ratio to 16:1. Adding excessive weight at this point wouldn't help us be mobile
