Team 41 - Full Court Shooter
 
Greetings everyone, just wanted to post a picture and video of Team 41's 2012 Robot.

http://www.youtube.com/watch?v=FWj5C...ature=youtu.be



Our robot is capable of traversing the barrier, balancing on the bridge and making full court shots. The turret can rotate 220 degrees and the shooter is powered by two CIM motors.

*Cause I know it will come up. :-) We have already fixed the illegally numbered bumpers.

Good luck everyone!

That is impressive, if you can make that shot 10% you would still be helping your alliance by passing balls across the field and keeping them away from your opponents.

I wish you the best of luck.

Very cool! We had that just about shot on our prototype, but the robot can't seem to get it even when we're hand-feeding. Glad you made yours work and good luck this season!

However, your bumpers are illegal. As per the Q&A, [R35] means:
A. Rule [R35] requires that the team number be displayed in four locations, no more or fewer.
You can't have 41 on both sides of your front bumper. :rolleyes:

According to the OP, the team already fixed it before the post :rolleyes::rolleyes:

Why put two CIMs on your shooter? I hope you beefed up your drivetrain with a couple 775s then.

Well, for that full court shot. We are using a similar setup with CIMs in the shooter, and FPs in the drivetrain. We certainly aren't getting range like that, though!

We're making full shots with 775's. If you could. I highly suggest you make the switch from CIMs to 775's (first find some that work), and put the CIMs in the drivetrain.

Otherwise, awesome robot! I love the design and intake mechanism.

Good luck!

It looks like a 775 running a chain to a drive wheel in the bottom right of the picture - I might be wrong, but it looks like they've got their drive covered.

That would appear to be an AM gearmotor connected to the intake. That being said, a lane dweller like this doesn't need to have a terribly powerful drivetrain. If an opposing 'bot even touches them it would be a penalty (unless they left the lane).

Re: Team 41 - Full Court Shooter
 
Yes, we decided to use two CIM motors on the shooter, they were the best option available to do what we wanted to do (go full court). We wanted to do direct drive to minimize complexity and to limit the vibration and noise of the shooter. While it's possible to build a really nice shooter with a gearbox, it was more difficult then we were willing to bite off.

Our drive is a single CIM per side into an Andymark Toughbox Nano. No, it's not as powerful as it could be, but it saves us significant weight that we could then put into the turret and the ball manipulator. Ideal, no, but everything is a tradeoff right :-), that's engineering.

You were right about the Gearmotor in the front, that powers the ball roller.
Thanks for all the nice comments, we're really happy with how the robot turned out this year!

Very cool! If you don't mind me asking, how much success have you guys been getting out of this guy?

With manual aiming and manual adjusting of the speed of the shooter wheels, we can pretty consistently hit the rim... we are hopping that once our codemonkeys get the camera and shooter wheel encoders working we can tighten that shot group.

As it stands right now we feel its accurate enough to make shooting from the back worth it, but it could definitely stand some improvement if we can squeeze it out of the machine.
