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.

Sensor Board

This board is located on the bottom of the robot and has the task of following the line. Sensor board includes: IR Sensor's Apds 9960's Multiplexer's Ams1117 We used 34 IR sensor's to follow the line, It has a receiver and transmitter , infrared waves are from 300GHZ to 430 GHZ and the length of these waves are from 1mm to 740nm. We could use a lots of things to detect red and green color but we choose APDS9960 Because it was more accurate and cheaper. We used two of them in the robot. Also we used multiplexer's because we didn't have enough pin's, 4051 and 4052 multiplexer's. We used Ams1117 because the input voltage of our color sensor (APDS9960) is 3.3Volts and our battery's are 12Volts so we need to reduce the voltage, you may ask yourself why didn't we use Resistor's to decrease the voltage , because it will be destroyed and we should use a lots of them and it will occupy a lots of space and the main reason is regulators make our voltage...

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.

OpenMV

 We had a lots of options to use for detecting the color of Evacuation Points , like OpenMV Camera , APDS9960 , Pixy Camera , We used OpenMV h7 plus to detect the  color of the Evacuation Point in the Evacuation Zone. The OpenMV that we used has a 5 megapixel camera and supports several communication protocols including UART, I2C, WIFI, SPI , USB , Bluetooth , etc.  To receive information from this camera , we used a 5 pin connector , which includes: VCC , GND and three digital pins. This camera has three microcontrollers named STM32H753, IS42S32800G 6BLI and 25Q256JVEQ-1912.
