We’re searching the best claw that woulld be able to turn to take the cap in each situation. Some ideas that have worked to you?
Thanks. Warriors

You have 2 options, a passive claw, and a active claw.

Passive Intake

How to make
Use 2 c-channels to enclose the cap from both sides, like this:

Advantages

  • Easy to make.
  • No motors used.
    Disadvantages
  • When rotating, it might slip out, as there is nothing actually holding it into place.
  • Takes up a lot of space.

Active Intake

How to build
Either build a claw that squeezes the top and bottom, or both sides. I guess the kit claw would work for gripping it from both sides, but you probably would want to look into better options. For the side claw, you could use 2 c-channels with some grip in between, and use a motor to grip it.

Advantages

  • Significantly stronger grip-wise.
  • Generally more reliable in terms of not having the cap slip out.
    Disadvantages
  • Harder to build compared to passive
  • Uses up a motor, and when you only have 8 v5 motors available, that’s important.

Hope this helped you out!

Gotta get that w a f f l e intake

in reality tho it’s really simple once you think about what a basic waffle iron does.
