    RTK GPS Driven Mower

    Occitan,Please understand that I have virtually no skill or experience with Arduino.Obviously, that includes interfacing beams to triangulate on to determinex,y position. Do you have a suggestion for beam hardware and software todetermine x,y position? Possibly a combination of these beams along withGPS can keep the mower on the correct course.

    Occitan,Thank you for your prompt response. I live in Dallas, Texas, and most ofthe grassy areas also have many trees. As you mention, the trees presenta problem for GPS. That is the primary reason to consider beacons todetermine x,y co-ordinates.Here is the Arduino code that drives the Astro Flight Controllers. TheseControllers control the wheel chair motors:=========================================================================#include <Servo.h>Servo servo1; Servo servo2;int i = 0;void setup() { servo1.attach(3); servo2.attach(5); }void loop() {// forward for (i = 45; i < 46; i++) { servo1.write(i); servo2.write(i); delay(5000); }// stop for (i = 0; i < 1; i++) { servo1.write(i); servo2.write(i);…

So manyof our cities and roadways are covered in trash. GPS could work much betterin this environment where there are not so many trees to obstruct.I hope that we can develop a 2 stage approach as I mentioned in the earlier email:1. Learn Mode2. Playback ModeWhat would you suggest as next steps? Thanks for your interest...Bob

  • I have built a remote controlled lawnmower that I use each week to mow my yard.I would like to make this mower robotic. My thought has been to add software/hardware to allow 2 modes: 1) learn mode using remote control, then2) playback, robot mode placing the mower in the same starting point as positioned in learn mode. Can this be accomplished with your hardware/software?
