Is a Car Jack a legal item to use?

[ksafin]

I wanted to ask here before I asked on Q&A and see if it could get answered.

I was wondering if a car jack would be a legal item to use on the robot, out of the box.

If you are talking about a hydraulic floor or bottle jack no.

No, more like a scissor jack:

That should be fine, as long as its usage satisfies safety considerations.

I suspect the Q/A answer would be along the lines of:

The purpose of this forum is to clarify specific Rules. We will not do design reviews. The design would be legal if it complies with all applicable rules.

Is there a particular rule you read that leads you to believe it might not be legal?

I recalled someone specifying some rule about not being able to use components that fulfill some aspect of the design for you (ie buying a prebuilt launcher). I thought it may have applied since it does lifting on its own (it was a stretch, but I wanted to make sure).

A Car jack is Considered a COTS Item. Therefore LEGAL. If anything bought for a purpose was illegal, then we wouldn't be aloud to use gearboxes.

This rule is non-existent. We purchased wheels (which satisfy an aspect of the design for us), of course we can use them.

I didn't mean it on such a basic level - but if a team made a launcher and decided to sell it that seems questionable.

What do you define as a basic level?

Do you see what I mean, this rule doesn't exist. How do you define a "basic" level.

I understand that it doesn't - just trying to clear up what I meant when I described the imaginary rule

Anything that fully or near fully plays a major aspect of the game - IE launches frisbees.

Kind of like purchasing a huge clay pigeon machine and sticking it on your robot would be suspect to question.

Would an electric car jack like this one be legal as well ? My guess is that it's ok as long as the motor is on the approved list but I just wanted to confirm.

I can't see a reason for it not to be legal as long as the motor you use is approved.

But if you're tossing out the motor anyway, you may want to go with the one I posted.

It's only $20 and it's reasonably easy to have a motor turn the winch to prop it up.

if your robot weighs 1-1/2 tons, you have bigger problems then the legality of that jack...
