[FTC]: FTC - Pictures and Videos Here
I've seen many requests for pics and videos of the new FTC Face Off! robots and competition matches in numerous threads, but I've not seen any responses to those requests, nor can I find anything new and useful posted anywhere else online. I encourage those willing to share to post links to their new FTC stuff here in this thread.

Re: [FTC]: FTC - Pictures and Videos Here
Here's a fun video from Team 2818 (G-FORCE)
It shows the robot and us scoring in Autonomous mode. We'll be competing in La Plata MD, in late Feb. http://www.youtube.com/watch?v=R1vM2FsDfcs Phil. Last edited by PhilBot : 30-12-2008 at 14:22. |

Re: [FTC]: FTC - Pictures and Videos Here
Very, very cool robot. And I think you've inspired one of our teams with a new approach to loading their scoring mechanism -- that's what this is all about, right? Thanks.

Re: [FTC]: FTC - Pictures and Videos Here
You got that right Rick TYler- If I have anything to say about it my teams' bot will look very similar

![]() Our team 417 uses a Lego mechanism to pick up pucks, and a 12-volt motor to lift them. 575 uses twin servos to grab them, and two more servos for lifting. Our third team, 418, doesn't have a puck-picker -- just in case you were keeping score. 418 is currently a walking robot that can't really do anything with the pucks, but it's a crowd pleaser.

Re: [FTC]: FTC - Pictures and Videos Here
I found the servos to be pitifully weak at lifting servos. Even with roughly 17 rubber bands attached to the back to help them left.

Re: [FTC]: FTC - Pictures and Videos Here
Well, I never said our 575 team liked the way the servos lift... They are trying to figure out how to use Lego motors for this.

Re: [FTC]: FTC - Pictures and Videos Here
Touche.
I will try and take a picture of the way we are doing it. It's not too pretty, but it works. Also, there is another thread in this forum where people have posted how they suggest we try it. |

Re: [FTC]: FTC - Pictures and Videos Here
We use use a third servo to rotate the puck picker.
We initially had a pair of servos on each claw (one to grip, and one to lift) but there were two problems. 1) We needed more than 180 deg rotation. 2) They weren't fast enough to "throw" the pucks into our dumping bin. So We attached a 40 tooth gear to a single rotate servo, and drive a 20 tooth gear with it. The two gripper servos are attached to the shaft that the 20 tooth gear is on. This way we can get up to a full rotation with twice the speed. You need to set the "period" on the servo VI to 0 to get maximum speed. To lift the puck bucket, we use two 12V motors (one of which has an encoder on it for positioning) |
