Robot Boot-up

Steps

Before you start the boot-up sequence make sure the regulator is connected to the battery. Then follow these steps in this same order:

1. Make sure the Arduino is not connected via USB to the UpBoard.

2. Plug the 12V output of the regulator to the Arduino.

3. Boot the Arduino microcontroller — for old versions of the mBot Ranger you will have to use a small screwdriver or pen.

4. Plug the 5V/4A output of the regulator to the UpBoard. This will make it automatically boot.

It's important to follow the steps in the same order. A typical failure is that the Arduino boots using the power from the USB. In that case, it will not have the 12V available for the motors.
