New power board

The power supply board we used so far had a couple of issues which we set out to fix in a new and enhanced version for the upcoming tournaments:

  • only 30×75 mm² in size and about 10mm in height
  • works without a relais (saves weight, also the power does not drop if robot falls down very hard)
  • power to servos can be killed by switch
  • power to servos or to whole robot can be killed in software
  • short circuit protection
  • on-board microcontroller …
    • checks battery level and adjusts RGB led accordingly (green, yellow, red)
    • switches off power if battery gets too low to prevent depth discharge
    • monitors usage and communicates it to sensor board

We have successfully tested a prototype and should switch all robots to the new power supply board in January.
