Just thought I’d share a project I did with ArduRover, RTK GPS and a can of spray paint, to do precision 2D graffiti vandalism in my local park
Started out with a 40ft smiley face.
The RTK GPS modules I used were the ArduSimple carrier boards with F9P. I’m very impressed with those.
For the spray cans, I just hot glued a servo to the end of a spray can, and plugged the PWM signal into the pixhawk servo 9 port.
Then I made a python dronekit wrapper script around the AUTO mission to shake the rover back and forth after every spray, to reload the spray can.
Hope you enjoy the project!
