Microswitch Board

In the Microswitch Board we have an microswitch witch we detect the obstacle's , the evacuation zone's wall , etc (you can learn more information about it in our programming blog)

Also we detect our alive and dead victim's with this board , we twisted aluminium foil so it will be conductive.

And we can now that the victim is dead or no because dead victim's aren't conductive but alive victim's are, and there is a lots of ways to detect the alive or dead victims for example you can detect them with color but we detect them with their conductivity or un conductivity.

Obstacle Board

This is our Obstacle Board , It contains an IR sensor receiver and transmitter, the transmitter sends IR ray's and the receiver receives it. Our robot detects obstacle's with its Sensor board but sometimes it think's its Rescue kit, so we designed this board so it doesn't think the obstacle is rescue kit.

Connector board

This board connects our robot parts to the Main Board witch our microcontroller is there. As you can see in the picture there is a regulator , two capacitor's and two motor drivers on this board. The regulator that we used in this board is LM2560 linear regulator (this regulator only provides 7 Volts and it doesn't heat up too much so it doesn't need a cooler) and it provides the input voltage of XL-320 Motor witch is 7 Volts. And we used L6203 motor driver to provide our Main motor (L1990) Voltage and Current. Those capacitors are 1000UF and we used them to reduce volatility, you may ask yourself why didn't we use a 2000UF capacitor instead of a 1000UF capacitor, because a 2000UF capacitor occupies more space.

LCD Board

We used this board to connect our LCD Display (TFT ST7735R) to our robot, Also this board has a gyroscope (GY-25) and a buzzer. The gyroscope is because we need to know if we are on a ramp Our gyroscope (GY-25) can communicate two different type of communication protocol's I2C and USART , we used USART communicating protocol, the accuracy of this module is up to ± 180 degrees.
