Designing of PCB (Printed Circuit Board)

Printed circuit board connects electrical components using etched copper pathways and it also provides mechanical strength to the robotic circuit. PCBs are composed of organic and inorganic dielectric materials with many layers.

The overall PCB design flow summarized into the flowchart is as shown below:-

The eagle software is used for generating the layout of the circuit. In PCB copper tracks are used on a conducting sheet. The pre-defined tracks reduce the wiring therefore reduce the faults arising due to lose connections.

Materials required in PCB designing:

• Laser Printer
• Over Head Projector (OHP) sheets or a wax paper.
• Electric Iron
• Two Plastic Trays
• Steel wool
• PCB/ Copper board
• Black permanent marker
• Drill machine
• Etching solution (Ferric Chloride)

So by using above material combination the electronic Hardware required for robots is designed.
