My friend Rob and I are out today with an RC car of his, rigged up with a GPS receiver so that we can program in a route for it and have it drive that path automatically. I love fun little projects like this. No rhyme or reason, just experimenting to learn something new. It worked! We drew a path on the map and the car followed it and drove around all on its own. Cool stuff. What practical use would there be for it? Filming, perhaps. What if you could draw a path and then have a computer controlled dolly car move the camera around? Automated seed planting perhaps? I’m sure there’s lots of potential uses for drone technology, but for us, the use was fun.
