Electrical

I was wondering what tools/supplies that I will need to get the control system properly.

Off the top of my head, will supplement this evening:
Necessary:

  1. The Game Manual, with special emphasis on sections 8.6 through 8.9. This isn’t first in the list by accident. Read it, and keep a copy handy as you wire to check gauges and what can and cannot be connected different ways. Read it again between build sessions.
  2. The user guides for all of the control system parts. Download 'em now.
  3. The control stuff that came in your kit of parts, including the stuff in the rookie tote.
  4. Pliers: at a minimum, diagonal cutting pliers and needle nose pliers, strippers being next, but the more different pliers the better
  5. Allen wrench set & screwdriver set
  6. More wire (stranded, rubbery-jacketed is best)
  7. something to use as a base for your control system. Plywood is common for rookies, but plastic peg board is much better.

Recommended

  1. Probably more motors and motor controllers, depending on your robot design.
  2. Zip ties
  3. Pads to tie zip ties down with.
  4. Anderson Power pole connectors and crimper, or lever nuts, or automotive style connectors and a crimper.

Edit: Alan got the stuff I was about to add below. The 1/8" screwdriver for the wago should be sturdy (not a jeweler’s style driver).

Edit2: And if you haven’t seen the screensteps live wiring site, put it around #2 or #3 on the necessary list.

7/16” nut driver (120A breaker wire)
5/16” combination wrench (for battery terminals)
Wire stripper
2.24mm or 3/32” screwdriver (roboRIO power)
⅛” screwdriver (PDP WAGO terminals)
5mm allen key (PDP power connector screws)
5/64” allen key (PDP power cover screws)
Needle nose pliers
Phillips #2 screwdriver (Motor controller screws)
Wire crimper

There’s more to add here as you get more advanced but this is all you need (as far as I remember) to get a running start
