Arm design (kitty's)

for those people working with me on my arm design

Let me in on that... what do u have in mind?

we have several designs going most of which focus around an extending arm with a grappling hook attached to a rope, originally the design was going to be telescoping pvc with the rope on the inside but now we are looking at other possible materials and extension systems

Oh yeah, I heard about that during the meeting, what do u plan to use??

we are looking at angled aluminum and extruded aluminum at the moment

well me and dan both feel that angled aluminum is the next best thing

Yeah, I heard that and to be honest, it looks like one of our best prospects for arm-ry.

Telescoping PVC might not work, as said many times before, but a stronger material such as, well, any sort of metal tubing might have a chance at working for this situation.

True, durable definately

alright so if we can figure out a means for getting it to extend we'll be in buissness, any ideas?

we can pnumatics only shoot the hooked piece

Pnematics works for me

Yeah, pneumatics. Say, out of curiosity, are hydraulics particularly hard to implement on robots?

explain to me how that would work please kitty not so hyper atm vv plus if you could draw it out that would be nice as well, though if we arnt going to use pneumatics anywhere else on the robot which id think has been decided yet though it may have been we should think of a means to do it with a motor and a gear, possible connecting the pieces to a chain and extending them that way is what i was thinking though i gotta work out how

umm hhydraulics arnt allowed XD pneumatic cylinders are and it doesnt have to be so long as we make sure we are doing it right other wise it can become a pain in the rear

charles your brillient we can run a chain on the end piece to have it extend we now just have to draw and prototype the idea

Kind to think of it, all this talk about the pneumatic pistons makes me revise my earlier statement >.>

Perhaps a jaguar motor dedicated to rotating (and thus extending) the telescoping arm?

And lol @ hydraulics' not being allowed.

EDIT: Blast, pre-empted!

Hardly yeah and if we shoot the grappling hook with rope might not work cause the power we use if too much wont work and less power will drop on our robot and damage it.

lols what was ur earlier statement on pnuematics and thanks i try ^^ anyway we should have more then one idea tomarrow that way we can compare and wiegh the positives and negatives of all of them which should lead to a superior design

good idea we'll do that

thats why we r puting the rope in an enclosed area and the graple hook is going to be connected to the end piece

I thought it was a hook attached to a winch somewhere lower, rather than a shot grappling hook?

Also; my earlier statement was in support of pneumatics. I rescind that statement >.<

I'll probably not write any of these down and be really out of clues tomorrow xD I still gots ta do my homework, after all.

presumably the arm would be "shot" in a manner that wouldn't jeopardize the robot that is one reason y the hook must be extended from the robot projectiles arent allowed XD we can still consider pneumatics though but im not sure i understand how it would work

u arnt alone with the homework there my friend and yea the hook is connected no projectile metal too risky we might hit someone we dont like XD

I'd rather the space for pneumatic components be saved for the firing mechanism rather than the more secondary function. >_>

Like I said, where's the shot? It seems more like a transfer of the hook from the edge of the top of the arm to the tower bar.

Uhh you have to write it down Lang said so and i mean hook attached with winch instead of rope. wrong statement im a
