The cmucam3 is... ive made some pretty fancy image recognition algorithms on it

Let me correct what I wrote before...The back up battery is tied into the custom board in order to charge it.

The main part of our autonomous is finding the balls but we did put major thought into how to knock off the ball without having to stop. We have figured it out with minor modification to our end effector. (Since I am not at school today, I do not have any videos..but will upload some soon).

Glad to hear that we will see 1024 at Purdue :cool:

A direct connection of your custom circuit to the RC backup battery would violate <R73>. This was clarified by an official Q&A response by the GDC here.

Per <R55> your custom circuit must be powered either via a 20A circuit from your breaker panel, or by one (or more) of the +5V pin(s) on the Robot Controller. I assume that you meant to say that the Robot Controller's backup battery will allow your custom circuit to continue running during minor power fluctuations.
Richard,

Team 358 posted a clarification to their question, and the GDC allowed teams to use the +7.2V "PWM pins" for power.

Thanks, Manoel.

This is a picture of the screen and on the left a little bit of the webcam.

Looks nice, wish I had stuff like that to play with.

IMHO the CMU cam is just as configurable.
We can find both balls (no matter where they are on the overpass) during autonoumous (we don't use Hybrid) and knock them down in 15 seconds.
We are using the CMU cam (to find the balls)and acoustic sensors (to find the walls).

Good luck Team 135. See you at BMR.

That's great, hard thing to do. I thought of using a camera but didn't want to deal with it.

How long does it take to see the ball and track it?

We get the first ball reliably but had trouble with 2nd and tus decided to go for points by driving around.

Re: Team 135 Autonomous
 
As asked for I have posted some videos. When you load the youtube page you will see that there are about 7 videos from the boilermaker regional. In the videos you will see what the robot sees after being processed by our software. It will put blue circle like things around what it thinks is the ball. It will the put little sun looking things in the middle of the blue circles. If the sun is green it has determined that what it is looking at is the ball. The yellow suns are what the robot has determined are the next best thing to go after.

these videos should answer the questions previously posted.

Anthony,

Very impressive. How did you do? How many times did you hit a ball and go around?

BTW I recognized crashes like ours. Our machine started to mysteriously start out and make a rapid turn to the left, other times file off a relay it didn’t have code in there to fire off.

We just drive the robot with the remote. Always hit about 4 lines and the opposite side's ball in CT. Took about 5 minutes to write the code for, too.

Yes, but they are not online or accessible right now. TBA should have the CT matches archived soon, so I'll post in this thread with whatever comes first.

Our scouts had you guys down as having amazing auton, I didn't realize you guys did that all with just the remote! Thats awesome! :ahh:
