Overview
CMUcam is a new low-cost, low-power sensor for mobile robots.
You can use CMUcam vision system
to do many different kinds of
on-board, real-time
vision processing. Because CMUcam
uses a serial port,
it can be directly interfaced to other low-power
processors such as
PIC chips.
At 17 frames per second,
CMUcam can do the following:
- track the position and size of a colorful or bright object
- measure the RGB or YUV statistics of an image region
- automatically acquire and track the first object it sees
- physically track using a directly connected servo
- dump a complete image over the serial port
- dump a bitmap showing the shape of the tracked object
Using CMUcam, it is easy to make a robot head that swivels
around
to track an object. You can also build a wheeled
robot that chases a
ball around, or even chases you around. In the
Gallery, you can see
pictures and videos of some of the robots we and others have built
with CMUcam.
How do I get
one?
Your first step (after
taking a look at the Gallery) is to go to Downloads,
where you can retrieve
the CMUcam User's Manual. This contains a
complete parts list
and schematic as well as a description of the serial
protocol and capabilities.
The easiest way to get your own CMUcam is to order it as a kit or
pre-assembled from one of the companies that have been licensed to
sell CMUcams:
After you buy and build CMUcam
you should test it using our JAVA computer
interfaces, also available
in Downloads. Then you're ready to build
your
own visual robots!
