Building PDA

Robot

This chapter explains step-by-step how to create the electrical and
mechanical components of PDA Robot.

Creating the Circuit Board

I created the circuit board using the M.G. Chemicals system. The M.G.
Chemicals system allows you to make your own circuit boards quick-
ly and easily. It is perfect for prototyping, hobbyists, and educational
applications. Technicians will be impressed with the high resolution,
while amateurs will be impressed with the simplicity of the system.
I purchased the Photofabrication Kit 416-K to create the PDA Robot
circuit board. It includes the following:
• One 3" 5" cat. #603 presensitized single-sided PCB

• One 4" 6" cat. #606 presensitized single-sided printed circuit
board (PCB)
• One 6" 6" cat. #609 presensitized single-sided PCB

• One 475 ml bottle cat. #418 developer
• One 475 ml bottle cat. #415 ferric chloride
• Two cat. #416-S foam brushes
