TRS Drawbot

This TRS Drawbot is a simple yet powerful drawing robot. The results look fantastic!

“The servos in your R/C car, plane, boat, or ‘copter are controlled by a stream of electrical pulses sent from the onboard receiver. The length of these pulses tells the servo what angle to turn to. You can connect your R/C receiver to an audio input on your stereo or computer and listen to this control signal directly. Because we have only two channels to work with, we can’t send “pen up” or “pen down” commands to TRS Drawbot, and are thus confined to single- or continuous-line artwork. In practice, this is not as much a limitation as it might seem. “
