If you find the prices of the current range of robotic lawnmowers just a little too high for your budget, you might be interested in a new open source remote control lawnmower which has been created called the Lawn Da Vinci.
Okay so it’s not completely autonomous but you can still add a little extra fun to those lawn mowing days, with the addition of a little remote control to the humble petrol powered lawnmower.
Check out the video below to see the Lawn Da Vinci RC lawnmower in action.
To improve reliability and reduce complexity, the motor driver now gets its signal directly from the RC receiver once it goes through the two relays controlled by the Arduino, which is always looking for a good signal. The Arduino and Raspberry Pi are powered off of a disassembled car cigarette lighter USB charger which takes the 12v of the batteries down to a clean 5v. I originally had it powered off of the Sabertooth but have better reliability this way. There are many ways to kill the motors. You can turn the remote off, push the trainer button, left with the right joystick, or push a button separate key fob and all of these will kill it.
