Using information from the BOM from the subteams, do proactive current draw planning to make sure the robot doesn't disable itself when it's driving, intaking, indexing, lifting & rotating the shooter.
The link above has a good process for doing this that we should follow. Note that last year's robot would brownout simply by accelerating forward with max power to the drivetrain, so we likely will need enforce power limits in software to help protect the robot electrical system:

  • Establish the max “sustained” current draw (with sustained being loosely defined here as not momentary). The WPI link suggests 180A
  • Enumerate the different functions of your robot & assign available current to these functions
  • Decide how to allocate power when the drive team is requesting the robot do things that will cause it to brownout. The drive coach must be involved in this decision.
  • For mutually exclusive functions in this analysis, consider enforcing the exclusion in software
