2019 OCCRA Roll The Dice - Game Manual
< R16 > Robots can only use certain control devices. There is no limit to how many
relays and motor controllers a Team can use. The Spike relay or the Adafruit DRV8871
are legal relays to use. The Victor SP, Victor SPX, Talon SRX, SPARK, and SPARK Max are
legal motor controllers that can be used. The compressor must be run by a single
automotive relay that OCCRA will supply to all Teams in the KoP.
All wires routed from motors and actuators must be secured to the strain relief bolt on
the side of the control box before entering the box and attaching to the various relays
and motor controllers.
Pertinent slide from the Kickoff Presentation:
In summary, the Spike relay is still legal. It is discontinued so it is hard to buy more, but if your team still has some they are allowed to be used.
Also general reminder, everyone please keep Q&A threads to only the OP’s original post and any follow-up questions they have so it can remain clear and easy to find the official answers to questions.
