Head for PeterBot (Xbee radio)

Hi all,

The head for PeterBot is ready, it is actually a Xbee Maxstream radio 2.4Ghz, so I will be able to  control the robot wirelessly.

Later on I will post a video.

Servos and Processor board for PeterBot

This is a shot of the processor and servo’s interface board for PeterBot, the processor board has a Microchip 18F2221 microcontroller (Schematic posted before). The processor board was designed using the open source CAD program called KiCAD and the Servo’s interface was designed using the popular program Eagle.

Etching a PCB board using the Photosensitive Positive method (PeterBot’s servo interface)

This is the first time I use the photosensitive positive method to make a PCB board and the results are very satisfactory for me, you just need to follow the instructions which I did post before.
Check this photos out.
