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.

I love the head movement! It makes the little robot seem alive. Really great work.

The head movement is very cool. It almost seems lifelike in a way. If only it could turn right =P

Thanks,

Programming the movement just right, took a while.
