Wat the Hook Gon Be?

[FotoPlasma]

We have hooks made out of 3/8" polycarbonate. Here's a picture.

Attached is a pic of a prototype very very similar to the one people will see in Canada. Maybe we'll get out some more pics of our robot soon.

We had a three prong grappling hook for a while, but at Philly we changed it to a two pronged hook with two little pieces that would go taut when there was tension on the hook. After this hook being knocked out when uncapping the 2X ball, we velcroed it in. Ours is inside our arm and comes out with tension and then the arm goes back down and the winch does the work. We are definitely going back to a 3 prong hook though, it's stronger and more dependable, but this time we are going to make it out of something stronger. As to materials and weight, I'm not sure anymore.

I'll try and get a picture later on, but I would like to describe our rather funny hook.

We have bosch extrusion with aluminum gussets (stronger than anything we got on our chassis ) and a piece of surgical tubing ziptied to the interior to increase friction. It's rather ugly-looking, but it sure is easily replacable.

Also, I like #852's hook... very, very cool... was that a spare you were carting along when you went up during award ceremonies, or were you winning Motorola Quality for something that accidentally snapped off your bot? (just kidding)

This year we used 1/4" steel rods bent into hooks. They have worked well for us, are light weight, and are easy to replace if they get a little bent.

its just extruded aluminum. nothing special its very light too it weights about .5 pounds per foot.

our original hook was aluminum..

made in machine shop at school. very simple but our over all design was 40lbs over weight.. so we changed it to the extruded aluminum. worked very well and now with that we can guard the top plat form and hang at any moment.

our hook is a almost exact representation of captain hooks "hand". it's made out of i believe 1/2" aluminum rod and fits on a track that is on our "boom". it serves as a 2 on one function considering it's Afro Engineered (sorry joel) for grabbing the 2X ball. It was made at our lovely sponsors/engineers work place Universal Studios. Therefor meaning it's built to last (was not created in any part by ford).

What kind of hook is it?
Double sided hook

What is it made of and how heavy is it?
We made it out of 3/4 in aluminum plate. It is kind of heavy (don't know actual weight)

Did you make it or did you buy it?
We made it.

How did you make it or where did you buy it?
We cut it out on the band saw.

From current competitions, which kind of hooks have you seen working best?
Ours worked every time.

Does it stay attached to the arm or does it come off when you hang?
It stays attached to the arm.

haha everyones is so complex... ours worked wonderfully, its just a standard bike holder that you screw into your garage ceiling and hang our bike on i think we purchased it at Lowes or Home Depot like another post mentioned.... it swivels on our robot (so nothing binds). too bad we only got to use it in L.A. this year (no nationals for us....)

we didn't have a hook, i just liked the topic title of this thread lolz
