We are interested in putting together a technology summer camp for HS (10-12) students where small teams actually build a working drone of some sort using existing designs/components. What low-cost designs would this group suggest? A multicopter would be really cool but I am not sure if we could come up with a truly affordable/survivable solution. Could we build a small AR.Drone sort of craft for $300? Would a rover be best to start with? Has anyone developed any sort of HS curriculum around drones? Is anyone interested in helping with this project?
