Self-made GPS Robot Tank This is a set I was experimenting with a few years ago. I installed the MissionPlanner software on my computer and moved it on a map. I experimented with an autonomous driving robot using ArduPilot. This is a very good deal for those who are interested or have knowledge of electronic work and can get this set connected and running again. Those who understand can add power to this and check the operation. Or, it's also a good deal for parts.
