projectile launcher

[Scoty2Hoty]

is it leagal to make a projectile launcher out of official vex parts, to launch a grappeling hook off of the robot? it will be using all official parts and some string. just wondering if it was legal.

[the killer's vex drive]

well they used a catupult out of vex parts in the guide didn't they?

[Scoty2Hoty]

hrmmmm.....

well this should be interesitng then.

[the killer's vex drive]

well if you are not going to use it in comp. then you can use rubberbands to hold it then a motor to let go.

[Scoty2Hoty]

i want to know if i can use it in competition though. it will be tethered, so... i'm not going to like shoot another robot and winch him in or anything, lol

[1086VEX]

acctually you could use rubberbands in the FVC comp
and it would more than likely legal.

[the killer's vex drive]

Nothing relating to FVC rules stated on this forum is official.

For official FVC rules please consult the FVC Game Manual which is posted here:

Chances are it wouldn't be legal(the launcher) The judges would view a potential for someone to accidently get shot or hurt. You can go ahead and try it though.

[Doogle]

yes it is my friend

[rebelyell2k5]

It would be legal as long as
1) The object does not become detatched from the robot at any time. Otherwise it is then a shooting 'weapon'.
2) It does not damage the field, entangle with another robot, or damage another robot.

You really have to be careful with that entanglement part, because I could see that happeneing very easily, and it would look fairly intentional, since you just shot something off of your robot.

Good luck, post some pics/vids if you do it!

So you mean a harpoon kinda thing with the nylon rope. Ill try it, maybe i could mount it on my tank tracked thing that is in the Gallery.

They used a ping pong ball shooter on a bot on the Vexlabs site.

I would be careful on what you use to launch the projectile. Pneumatic actuators are not competition legal even though they are Vex made parts. (unless I am mistaken, I am almost positive they are illegal.)

Just because they shot a ping-pong ball doesn't make it legal for FVC. I think this will be seen as intentional endangerment to other robots because you are shooting something.

The Vex pneumatics are illegal for the Hangin' a Round challenge, but there have been rumors of them being allowed next year. But that is a rumor it is not official.

Yes, please, I'd like some pneumatics with my rack-and-pinion gears.

How will you use them you would have full lock in either direction.

[Stonebot]

how would u launch the grappling hook with enough force a to get it to go high enough and what will the grappling hook be made out of??

[Astrus]

I've seen a video of a robot that used a grapple hook to hang from the bar... the video didn't show the shooting part, but I think it'd be safe to assume it was somehow shot up there.
