Can Springs be used in Vex robotic competiton starstruck ?
I know Rubber bands can be used but can I use springs?
Correct, rubber bands are legal. Springs are not legal in VEX, unless you take out springs from the old VEX clutches. Inside each VEX clutch is a tiny spring that can be used for anything you like.
Bryon has said everything there is to it, but as a side note, depending on the intended application, there are other springy materials you could potentially use, for example a strip of polycarbonate when bent/under force will want to spring back to its original shape.
It may have changed but my recollection is that the clutch spring can not be cannibalized. I think the only legal spring for competition is the spring in the claw.
Yes they can be.
Latex tubing 275-1262 can be used as an elastic spring. Also there is a spring in the claw.
Anything non electrical or pneumatic can be “cannibalized”.
A good example can be found here.
Is there any videos of mechanisms in which springs are used? I’m having trouble figuring out how a tiny springs could be useful.

And don’t forget, you can “stack” multiple springs on top of each other to make 1 big one.
Thanks you all!!!
