DESCRIPTION

In the beginning....  The parts list is below and the video description on how it will work...

ROBOT LAWNMOWER PT1 - PARTS USED  https://youtu.be/IaSaRRnZU8c

Here's a list of the major parts

  • RGB sensor
  • OLED display
  • Lithium ion batteries
  • Wheels
  • Wood
  • Motors
  • Ultrasound sensors
  • Arduino Mega Arduino Mega 2560



Attaching the wheels to the motors was tough going, here is how we got the basic chassis made and connected the wheels to the motors.




Once we had the chassis made, the motors fitted and the wheels on...  it was time to take it for a test drive...  We found that the batteries and motors were a little underpowered, so we decided to apply a little over-voltage to the drive motors.




We then needed to start fitting the electronics.



Testing was great fun... and when it finally cut grass! Whoop whoop!  It took us a long time to get to this point...



Here is a technical video describing the building blocks of the lawnmower fo those that want a little more detail.
