Loki Electronics

This page describes Loki’s electronics.  My other robots use similar, with variations.  So, most of the core info is here, but there may be details specific to each robot on its design page.

All of my robots use a main processor (laptop or PDA/Phone) for the higher level software, and a microprocessor for sensor interface, and often motor or servo control.  Loki has a laptop embedded in his chest that communicates via USB to various electronics.

For the MicroProcessor, I have been using a PIC-based Mark III controller board, which used to be available here, but I have heard may not be available any longer.

Also, I found I this cool site for making PCB boards,  PCBWeb. It looks really good!  Let me know if you’ve tried it!

1/15/2013 Update!   I finally moved to Arduino!  See Arduino section below.
