An autonomous lawn mower #Robotics #Automation @kt320

Via Hackaday, two years ago Kenny Trussell designed a autonomous lawn mower based on an existing riding mower:

It’s brains consist of a PixHawk board running Ardurover, an Ardupilot derivative for ground vehicles. Navigation is provided by a RTK GPS module that gets error corrections from a fixed base station via an Adafruit LoRa feather board, to achieve centimeter level accuracy. To control the mower, Kenny replaced the pneumatic shocks that centred the control levers with linear actuators.

The mower has been cutting large fields (five to 18 acres). It uses the Ardupilot Mission Planner software for which he wrote a custom command line utility to create a concentric route for the mower to follow to completely cover a defined area. It runs off a 386 laptop which is still going strong.

See the video series below for a documented look and the Hackaday article here.

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. I am honored to have a blog post featuring my autonomous mower! I hope to create new updated videos soon! I am now using the Ublox ZED-F9P RTK GPS base and rover, which is awesome. I will be glad to share my experiences. And, yes, I use the mower to do REAL work all the time, cutting real grass on my farm.

    The Adafruit Feather M0 LoRa is a great little board! I have several.

    I’ll try to get on Show and Tell sometime (been there twice before on unrelated projects) to share!

    Thank you, Adafruit!

  2. Hey Kenny, it would be great to have you on Show & Tell – you have a great project there! And do let us know if you post your results more, I’ll post a follow-up blog post.
