1583 after 3 weeks

I noticed you guys were controlling that prototype with the VEX controller. I love it!

Hi Alex......We are only kicking from one side of the octagon. Our process for kicking in autonomous is to (1) drive to the ball (2) capture it with the dribbler (3) Acquire the vision target with the camera (4) rotate the robot to aim at the target while possesing the ball (4) kick when pointed at target. During teleoperated we also hope to have the camera and Crio aim the robot to kick the ball as well. As it stands now we have four CIMs driving the chassis, two FP spinning the dribbler and one CIM powering the kicker. That ends up being seven jaguars stashed in that octagon. There's not much wasted space to say the least

Paul.....We always drive our prototype chassis with Vex. Can't beat it for getting things up and running fast. It also gives the programers something to work with without waiting for the CRio

Looks sweet. Nice drive train.
I have only one critique. It looks like you are trying to score the balls by throwing them into the goal. There's a group of chains that will prevent that. Dean Kamen, at kick off, siad that rolling them into the goal was the way to score.

The vex controllers have been great for prototyping. They are so much less work that putting on everything needed to run either the current system or older IFI systems.

Our wheel testing prototype ran via Vex, our ball magnet prototype use a Vex controller, we slapped a Vex controller on an old frame to test our prototype winch and our t-shirt robot is controlled by Vex.

Hi,

What motor and gearbox are you using for the rollers?
It looks like the cim 12:1 gearbox and a fisherprice motor. But how were you able to connect both of them?

Looks like an FP through a Banebots P60 on each side. If my deciphering fuzzy number skills are good it's 20:1.

The Banebots P60 is designed to work with a motor with the same package as the FP. Some work must be done to change the FP pinion, but that is the only modification necessary to make the combo work if I remember correctly.

I'm sure somebody from 1583 will be around to chime in with the details.

Xavier...Kevin is right, our prototype has Banebot 36mm 20:1 gearboxes with 385 motors. The competition robot will have the same transmissions with FPs. We've already installed the motors on two other transmissions. It's an easy mod once you figure out how to remove the pinion from the FP and press on the 3.2 mm 15 tooth pinion from Banebot. The P60 20:1 gearboxes are just as easy to install the FPs on.

Thank you

[Galum]

Very nice indeed =)

Just a piece of advice, try using the Andymark planetary gearboxes instead of the Banebot's, the Banebot gears are unreliable and tend to breakdown in the middle of games (a la several of our games at the championship last year ;-) )

[NOV8R]

Hi Gal...sorry to hear about your experience with Banebot gearboxes. We've used them since 2007 with no problems. They have had their share of problems but the folks at Banebots have made all sorts of enhancements and improvements with input from FIRST teams. They are only fifty miles up the road from us (Loveland, CO) so we talk to them frequently. They are great folks to work with. So is AndyMark. This year's robot will be about 50/50 Banebot and AndyMark parts.

[Galum]

Oh, in that case no problem We were using the older gears from the KOP and they didn't preform very well

That's a really fast spinner. Have you considered moving to a 26:1 or possibly a 64:1 P60 gearbox with a FP?

Hi Andrew...the motors (FPs) are both on jaguars . What you see is max speed. We can dial in any speed we want. One of the things we've discovered from playing with the mechanism is that we can 'steal' a ball from another robot if our 'dribbler' spins faster than theirs.

Interesting concept but with 3" of intrusion into there frame plus "3 of bumpers then your 3" of bumpers this ball won't een intrude into yur frame perimiter. All that making stealing a 9" ball rather hard.

[NOV8R]

Corey....Good point. It will still work if the other robot doesn't have the ball 3 inches into the frame. Speaking of bumpers we are going to spend sometime this week seeing what effect that may have on our kicker trajectory.
