Control box consists an LCD display, 3 buttons, 4 potentiometers, 5 LEDs and ON/OFF switch. All components are connected to the circuit inside the box. The circuit is made out of 3 microcontroller - 2 atmega8 and and 1 arduino. I could use only arduino to control the robot, but I wanted to make a system of three microcontrollers all connected together.
LCD display serves as menu. You can choose 7 differrent programs or manual control with potentiometers. When you chose manual control, LCD will display position of each servo.
