Need for Speed

Finn Moore, Dimash Umirbayev

Idea

• Create fun and exciting remote-controlled cars with live video streaming
• Compete in a fast-paced racing game and explore inaccessible locations

System Architecture

Controls

PS2 controller hacked over SPI

• Custom PID module in C
• Speed control (PWM) and direction (H-Bridge) controlled with right joystick
• Camera panning servos controlled with left joystick
• Camera position reset: X button, LED flashlight toggle: O button
• Start race with Start button

Wireless Transmission

• XBee modules on base station and each car wirelessly transmit via UART protocol
• ESP32-CAM module records, compresses (JPG), and transmits video over UDP

Finish Line Detection

• Blue finish line is detected using the color connected components mode on PixyCam modules on each Car
• Sends data over XBee indicating which car crossed the finish line
• When this data is received, a UART Interrupt is triggered on the base station stopping the race and displaying winner
