This is really Scout_bot version 2.0. I added the pan tilt head (Robotshop.ca) later. Anyways it adds some personality. He is built on an old telephone base that I had,added 2 servos for a drive,wheels, battery and electronics. I decided to put in a homebrew IR detector (maybe cause I'm cheap...). Yeah, it took a while to get that working.
For the electronics a Pic16F628 micro with Picbasic was used.
Update June 12,2010
Added IR remote control to Scout_bot. Used another Pansonic PNA4602M IR detector
and an old Sony remote. Pic PortA.2 was used for IR input.
From the top a look at the breadboard.
This is the IR emitter and the Pansonic PNA4602M IR detector on the head. The pic16F628 generates a 38Khz PWM signal
and is then detected by the PNA4602.
