Component or Sensors needed for Position Measurement.

Hello Everyone,

We are making an Automated Lawn Mover, and we have a question as how can we make the bot move by giving X,Y co-ordinates or make it to go and come from any measured point to a reference point.

What are the components needed along with an Arduino board. Please Help.

Thank a ton !!! :slight_smile:
