Hey guys, so I'm currently in college and I'm really fascinated about drones. So for my senior project (capstone), I would love to try to incorporate it with the usage of drone. My project: So essentially, I need a drone that could go from Point A to Point B without manually controlling it with a controller. My team and I, already thought of using a GPS and a receiver to put inside the drone and make a transmitter and place it at point B. Our biggest dilemma right now is that we need a drone that will fit inside a cylinder tube with a diameter of (4 inches). We're unsure if there's a programmable drone that small that could fit inside that tube with homing capabilities. We're currently in research phase of the project so I was wondering if anyone could point me to a good place to start to look for programmable drones that are small enough and with homing capabilities that would be a great help!
