Control circuit

In a student competition, our team built a robot that could follow a line, lift weights with a robotic arm, and move using motor control. I was responsible for the control circuit design. I created the schematic with ESP32 as the main controller, connected IR sensors for navigation, motors drivers for both movement and the robotic arm. I also added an LCD display for system status and a buzzer for alerts. Finally, I designed the PCB layout and generated a 3D preview for fabrication.
