CMUCam Object Tracking (with Cortex and RobotC!)

VEX V5 General Discussion VEX Robot Showcase

Hey Guys,

Have been meaning to post something with the CMUCam for a while now. It is one of my favourite robotics toys (and VEX compatible)!

The CMUCam is a small but powerful embedded camera module that is able to track objects based on their colour. It can track at around 25 fps at 320*240 resolution, and about 11fps at double that resolution. It can detect both position and size of an object.

Here is a video I made of the CMUCam2+ tracking a green clean sweep ball:

And here is another one I made a few months back on a small fire fighting robot that can track a flame (The shell is a rapid prototyped Hummer I made in CAD).

Big thanks to the RobotC Team for adding CMUCam support for the Cortex, and for helping me to get it working at the last worlds.

I’d love to see a basic tutorial on how you setup the flame tracking robot.

Consider this a video request!

Excellent work,

Cheers mate,

I would like to set up a video tutorial, but am in the middle of exams right now and it would take quite a while to go through the whole setup and explain it properly.

Will be finished in a couple of weeks though, so will post some more detailed info then.

The best place to start would be here:

And the CMUCam2 Manual::

If you have any specific questions about the camera (or the rapid prototyping) I am happy to answer them.

Hey, I’m seeing that in your screen capture that you actually have the CMU camera functions in the function library…how do you get that?
