Any ideas?
Hey guys! I've been doing a robot with the BS2 for a couple years now and I'm wondering if it can handle a boebot cam? I'm thinking about using the robot as a facial recognition system or something along those lines. Thanks!

Thank you so much, again!

The ColorPAL is for contact color sensing. It needs to be very close to the object it's sensing. You could use it for a line following robot where you're using different color tapes on the floor for different branches on a path. The ColorPAL sensor would have to be mounted just above the floor for this to work.
You really want to use something like the CMUcam. Parallax's version of the CMUcam1 is $140. A plain CMUcam1 is $100 and would need some simple modifications and mounting hardware to hook up to a Stamp-based bot. This is not a cheap sensor, but sounds like it's closer to what you need for what you want to do.
Another inexpensive sensor to consider is the Linescan Imaging Sensor (www.parallax.com/Store/Sensors/ColorLight/tabid/175/CategoryID/50/List/0/Level/a/ProductID/566/Default.aspx?SortField=ProductName%2cProductName). This can be used with a Stamp and you could mount it on a servo to do a scan of an area. The main issue is again lack of storage and speed on the part of the Stamp to process the successive scans.
Remember that, by the time you get a Linescan Imaging Sensor and a servo, you're getting near to the cost of a CMUcam1.

Servo motors respond to pulses that vary from roughly 1ms to 2ms in width. With regular servos, this pulse specifies the desired servo position with 1ms representing one end of the mechanical range and 2ms representing the other end of the range. With continuous motion servos, 1ms represents full speed in one direction and 2ms represents full speed in the other direction. 1.5ms represents a full stop.
