Hello, 

I am currently trying to work out a reliable 4 wheel rover to make or buy for a project I am working on. The rover will need to be reasonably big, enough to carry all necessary parts, around a 200 gram payload, and run for 12-20 min all autonomously. I would love to get some advice on the best system out there that I could buy off the shelf or the necessary parts I need to build one. I would love to build this with a pixhawk with the duel GPS to run autonomous missions and eventually plan to have it work with two UASs using mission planners swarm function. I am really looking for the most reliable system that can run, say 50 times before having to do any repairs if is just running autonomous missions on a model airplane runway. Please let me know if you can help me out or direct me somewhere else. 

Thank you, 

Graham Bryan
