Autonomous mower

I have no experience with rovers while several years of experience with multirotors and APM/Pixhawk.

I would like to turn my 16HP Weed Eater mower in an autonomous mower .

The idea is to replace the manual steering with a electric one from automotive and to use a RTK M8P gps to allow precise positioning during grass cutting missions.

Any suggestions are welcome

Its a great idea - looking forward to the photo’s and videos.

Thanks, Grant.

Sounds like a great application for collision avoidance too!

I follow your proyect too, I have this idea in my wishlist for many time :smiley: ; I was suggested to replace the steering with an electric automotive one too, perhaps that`s the way.

Happy that this topic get some interest :slight_smile:

Fortunately my mower has an Hydrostatic trasmission , so the only actuators I’ll need apart the steering will be

  • brake actuator , actually a pedal that disengage a pulley on the transmission belt
  • Automatic transmission, a lever that has an operation similar to the automatic gearbox of a car with the nice feature of reverse position that can be used to stop or reduce the speed of the mower , something that a car cannot do.

I have bought a used electric steering unit for 100$, will receive it in a couple of weeks and start to work on it.
In the meantime, I’ll post some photos of my mower.

this is the mower without the steering wheel but with the electric steering unit on the side, as expected it is a brushed motor and I will use a Sabertooth I already have to drive it.

Unfortunately the original bevel gear is very basic and I would like to improve it, any suggestions ?
