This robot uses the same camera that is supplied in the KOP for FRC. also, i added a dual ulltrasonic sensor program, and a line follower program. i used EasyC Pro, and here is a link to the
(https://vexforum.com/local_links.php?action=jump&id=51&catid=26). mechanically, this robot has a three-jointed arm and a simple claw on the end to pick stuff up.

in this picture you can see how i was able to change between user-control mode and autonomous with the switch labeled 1|0, and then once the robot is in autonomous mode, it switches between the three using the limit switches.

video of the camera tracking a green light box i recently made:

I noticed that if you moved the Target Light away from the Vex, the Vex would move closer…
If you move the Target closer to the Vex, will the Vex Move back???
Very nice Tracking of the Target Light!!! That is the kind of Coding that is need to have a FRC robot place the Keeper on the Rack in Autonomous Mode!!!
It looks to me like the tracking isn’t sensitive enough. When I programmed our demo bot with a cmucam and a rubber band gun, I had to make sure the robot made it to the necessary position to hit the target. Unfortunately, I can’t see the code (not on my PC, at least). There are probably several ways to make it follow better. Could you post your code in the code tags?
Instead of using a camera, could you just use a light sensor with a color filter? I’m not really sure though, because I don’t have too much experience in programming. The most i’ve ever done was bumper sensors to make the robot back up and turn .
umm, no i dont think it would be possible to use a light sensor. it just wouldnt be accurate, the camera “sees” the green light by taking a picture of what it sees and according to what colors you set it to track, it makes everything of that color highlighted, picks the largest, and tracks it.
the red cathodes are just for looks
if anyone isnt able to download the code or wants a wiring diagram, if you give me your email address ill send it to you, but you will need EAsyC Pro.
What I meant was that I had easycPro installed and licensed on my computer and then switched it to a club laptop. I can no longer view easycpro projects on my PC
It looks like the robot drives proportionally on the x-axis (horizontally) but can only drive forward on the y-axis (forward/backward).
You can look at the code I used here. Hope this helps!
yeah it is, i got it from a broken desk lamp and thought to use it with vex. its just more handy because it will hold a position unlike the other switches.
(and nice cold-cathodes
