Re: pic: 2010 Los Angeles Regional Champions
Congratulations on the win.
I loved watching the videos of the LA finals. It was some of the most intense and nail biting matches this season. I noticed that all the robots on this alliance have uncommon drivetrains. 330 has 4 wheel drive with omniwheels and two massive pneumatic wheels. 1452 appears to have a 6 omniwheel drive. Of course 1717 has its lovely swerve drive. Does anyone have any info on 1717 drivetrain? By the way, 1717's hanger (I guess its actually a lifter) is seriously cool. |
Re: pic: 2010 Los Angeles Regional Champions
Can I answer any questions you have regarding our robot this year?
|
Re: pic: 2010 Los Angeles Regional Champions
I was very impressed by your robot last year. Was there any improvements to the swerve this year? Also, I was curious if each wheel is independently steered and what options you have to control the drivetrain?
I hope your team come up for CalGames, so I can get a closer look (that goes to 330 and 1452 too). |

Re: pic: 2010 Los Angeles Regional Champions
So are you folks still tweaking an end game that lifts another robot?:rolleyes:

that is beautiful. Are there any more pictures up somewhere of your machine? |
Re: pic: 2010 Los Angeles Regional Champions
That was the original plan, but after San Diego we thought lightening the lifter and lowering our CG was more important.

For 1452, if there is a picture of the underside of your drivetrain, I would love to see it. I love robots with unique drivetrains. |

![]() Our ball collector consists of a metal roller and centering paddles covered in Sorbothane, which has a coefficient of friction of about 15. The roller is powered by a Mabuchi motor and the paddles are powered by a window motor. The paddles center the ball and grab on to it which allows the robot to spin and move while still maintaining possession of the ball. The kicker has surgical tubing attached to it and is pulled back using a dog-eared winch. When the kicker is pulled back to the desired angle, which is measured with a potentiometer, the winch is released via pneumatic piston. ![]() ![]() Yes, our lifter has a compressed gas spring on it. We release it using a lever with a pneumatic piston on one end and the gas spring on the other. I unfortunately am unable to find a decent close up of the lever. Sorry :( |
Re: pic: 2010 Los Angeles Regional Champions
kudos to the D'Penguineers for sharing so much detail and great shots of their robot. Excuse me while I wipe the drool off my chin :)

Re: pic: 2010 Los Angeles Regional Champions
1717, you guys built an amazing machine this year. In a year where so many robots look and act the same, you pulled off an extremely creative and unique design that performed like a monster, and managed to make it elegant and good-looking, too. This is a team to watch at Atlanta.

Re: pic: 2010 Los Angeles Regional Champions
Wow! I knew 1717 had an great robot from the webcast, but these pictures really show how exemplary and innovative the team is. I love the gripper. Thank you for posting such great pictures.

Re: pic: 2010 Los Angeles Regional Champions
How does the lifter work? I understand it has a gas spring but how is it powered and how does it latch on to the tower?

Re: pic: 2010 Los Angeles Regional Champions
1671 wishes to congratulate all of the winners from the LA regional. It was a lot of fun and everyone on our team enjoyed going.
Can't wait till next year see you guys there again. :) |
Re: pic: 2010 Los Angeles Regional Champions
I was continuously impressed by seeing your robot compete. Thanks for answering my questions about your robot! That gas shock and those sorbothane grippers were quite impressive. However... I neglected to take pictures of your robot, D:. Do you happen to have any pictures of a close up of one of your swerve models inside the chassis? My team is trying to CADD a swerve drive right now, and we were wondering if your robot uses any sorts of bearings/bushings/devices when rotating and steering each of your swerve modules.

It works very much like double doors that are push-only. The doors are two free-spinning half-wheels that are restrained by surgical tubing. When we drive into the pole, the pole pushes in between the two wheels, forcing them to open. After a certain point, the pole pushes past the wheels, and the wheels snap back into place, locking our robot around the pole. A wheel near the bottom of our lifter touches the opposite side of the pole, ensuring that we keep tight to the pole as our gas spring pushes up off the tower. |
