1114 Launcher

I was at GTR this weekend. Obiviously 1114 dominated. I was just wondering if anybody knew how their launching mechanism worked.

no gas shocks, no pneumatics

they shoot with the power of 1 fischer price. It pulls back a large linear bearing rod pulling surgical tubing taught. Then they have a pneumatic cylinder that punches the motor out of the powertrain and frees the shooter.

It's not a gas spring. Its a metal shaft on a linear bearing attached to surgical tubing, the surgical tubing in winched down by a FP (I believe) in a dewalt gearbox. Then they use a dog gear as a clutch.

Edit: looks like I was beat to the 'punch' :P

According to Clarke's third law, I believe their entire robot works by magic.

That sounds about right, maybe little nomes live inside the chasis and work there magic.:D

Way to go at Colorado Winnovation, you guys ted us with your shooter. (I'm sure we would have won if our launcher worked:p )

Re: 1114 Launcher

ohh and another little timbit (you need to be Canadian to get that), the top arm of their roller claw is actually on a bit of a pivot and has a little piston at the end of it, so when they fire I bet they retract the piston to release the pressure on the ball.

Timbit #2: if you look closely they have another mini puncher on the end of their roller claw which they can use to poke the balls off the overpass. I've only ever seen them use this once, its another shaft in a linear bearing connected to a small piston.

It's true. That machine is above and beyond anything I have ever seen- it rivals 25's 2006 robot in excellence- and that robot was GOOD. The winch/crossbow idea sounds interesting- hope a member of 1114 posts with more specific details on how it works.

But ending my ramblings- 1114's shooter was awesome. As Don said in Looking Forward's Week 5 predictions thread,

or maybe they will just keep it thier own little secret:cool:

Ok, how does one go about and stop your robot from scoring? :p

Re: 1114 Launcher

I don't think it's necessarily the shooter on Simbotic's robot that makes it work so well, it's the fact that every single part has been worked on and fine tuned to do its job efficiently. The drivetrain is fast, the pick-up is reliable, the auto racks up tons of points. Probably most importantly, their drivers are very skilled. Good driving is an enormous part of the game! If they had a bad driver trying to control it, they would just be just like any of the other dozens of good teams this year.

Re: 1114 Launcher

Could we see a pic of that dog gear? That'd be great since I'm still learning a lot of mechanical techniques involved with FIRST robots:)
