They can track from their cameras. It seems effective for moving, but I've noticed some troubles when moving in teleoperate as to tracking.

Re: Autonomous patterns?

There are robots that use the autonomous period to obtain empty cells (such as 217) and there are robots that use the autonomous period to load their robot up with moon rocks so that they have ~20 moon rocks to score by the end of autonomous. There are a lot of strategies that use the autonomous period in a constructive way.

We can pick up from the floor or receive rocks thrown from a PS. In autonomous we often drive from corner to corner and let the PS top off the hopper. We may try picking up an empty cell this weekend (but don't tell anybody - they're not even supposed to notice).

Then theres the tight spin, first done (that I know of) by BOB (85) at Traverse City on week 1 and now copied by many others (including us!).

Personally, I don't see the point of going straight. It just puts you in the scrum and makes you a target.

WAY TO TELL THE WORLD WAYNE! YOU MAY BE THE RULER OF WAYNE'S WORLD BUT NOT OF OURS! KEEP OUR SECRETS SECRET!!!!!!! :P

Re: Autonomous patterns?

I'll have to admit that our robot just drove straight out and did a slight right-turn to keep jams from getting too tight. (It also helped for pinning robots to our outpost...)

I did talk to someone from 234, and from what I understand, they have written a program that allows them to draw a line on a computer, and it compiles code for the bot to do the same thing. They really did seem to do well in autonomous...

Re: Autonomous patterns?

Spinning hasn't seemed that useful to me unless you have a robot that can really build up some RPMs. If you're not spinning very fast, the PS just starts timing the spin and tossing moon rocks in anyways. I saw a PS at LSR that would grab two rocks at a time and toss them when the trailer swung around, then grab two more rocks, wait... It certainly makes life more difficult for the PS, but it doesn't really make scoring impossible.

A better plan starting in the corners is to pull a slight turn into the long wall and drive to or just past your outpost. If you're a tall robot and you pull your trailer slightly past the outpost, you're nearly impossible to score on. The PS you started in front of is unlikely to make a half court+ shot, the PS in front of you isn't likely to score over the top of your robot, and the outpost PS isn't going to have the range or the vision to score over the mass of robots in center field. Granted, you're in trouble if the robot in front of you doesn't get out of the way, but he's going to be in more trouble in that case anyways.

Re: Autonomous patterns?

216 does a figure 8 in autonomous mode and tends to pick up an extra 4-6 balls before telop. starts. Maybe gets 1-2 scored on by a good human player.

Re: Autonomous patterns?

As seen at Davis, there was a lot of success in a forward followed by backward spinning action as it was done by many teams. Another good one, by 604, was driving to the outpost area and they were filled up to be able to dump upwards of 15 or 20 balls at the start of tele-op. The final amazing one i saw, and i can't seem to remember what team it was, was a tracking one, it would follow and lock on to a trailer and be ready to dump in tele-op, they could even dump in autonomous, it was pretty cool.

Re: Autonomous patterns?

Another one for the corners, if you have a human-loadable robot, is to pull along to your fueling station and get loaded up. It creates a difficult angle for your opponent's PS, and they may score a few, but nowhere near the devastation that would happen if you were right in front of them.
