Number of required actuations for claw

VEX V5 General Discussion Technical Discussion
#1

The most prevalent design as of now is a clawbot, and people are doing both motorized and pnuematic claws. There’s been a lot of discussion of how many actuations you can get from 2 tanks of 100 psi air, but how many do you actually need?

For skills, I estimate 2 actuations for preloads, 2 for the 2 cubes on the field, 2 for the stars in between the alliance tiles, and 2 for the 4 corner stars, so I’ll put 8 as a minimum.

The most actuations I’ve heard of a claw getting is 52, so I’ll put that as a maximum.

So between 8 and 52, how many actuations are actually necessary?

#2

We got 52 full actuations, but the last 5 or so were pretty sketchy. I think 35 is a nice place to be to be comfortable in a match, but of course more is better. We also run pneumatics elsewhere in our robot, so we’re never really going to get all of the actuations.

#3

Wouldn’t all those numbers need to be doubled since most people are using 2 pistons for their claw

#4

No, that is with two pistons

#5

Could a claw be built using one piston that is still strong enough and opens wide enough. To be useful?

#6

I dont think so, mostly because you dont really need to save pistons, and the difference in power is so great

#7

We get about 32-36

#8
