Where can I buy:
like to refer to a Web site where I can buy it.
These are the servos used: http://letsmakerobots.com/node/9099
The pan/tilt sensor bracket was not designed for heavy loads, only lightweight sensors. Although the servos might have enough torque I don't recomend it.
I find a PDF document and the product I had lete after number 23rd
but could not find the spot where I could buy?
