Autonomous Robot Car with Display

Inspiration: I only did the EECS16b robot car using simulation, so I want to build a real one with a new design and more functions.

Goal: Build a robot that supports voice control and has a OLED display and a ultrasonic sensor.

Description: The board is powered by a 9V battery and is stepped down to 5V and 3.3V using LDOs for other components. Another 9V battery is used to connect to a L298N board to power the motors. An ESP32 is used to process signals from a microphone and give signals to the display, the sensor and the motors.
