Rover 5 is a new breed of tracked robot chassis designed specifically robotic usage and carried PCB circuit. The chassis can be upgraded into two or four motors and encoders making it ideal for mecanum wheels. There are two brushed DC motors with 210mA free run and 2.4A of stall current at 7.2V. The body was created by durable plastic and it can move for 1km/hour.
As u can see, picture above show the internal body of robot chassis which contain 2 motors in left and right side. Each motor connected with 2 wires (red and black) for supply and also ground. These wire will connected to TIP120 on the circuit and interface with ATmega328.
The instructions provides by an ATmega328 are HIGH or LOW. High means 5 volts and Low is 0 volts. The operations of TIP120 is like a switching mode that control the input for the motors.
