On the other hand, the figure 4-7 explains how to connect the JTAG pins to the

Atmega16. The JTAG is used to program the microcontroller.

Appendix B shows the layout of the circuit made in Eagle. The shape of the card

was chosen to be that one in order that it can change neither the sensor locations in the

platform of the old design nor the size that the cards hold in the robot bottom platform.

In figure 4-8, the sensors’ positions are indicated by circles.

The board has just two layers and the wire’s width is 16mil.
