My thought exactly. Why send men to the frontline when we can just send drones? At the moment, we are only sending flying drones but why stop there? Why not send land drones? If we can send an unmanned exploration vehicle to Mars, surely we already have the technology to do the same on earth. Uncle Google told me that we already have things like this:don’t you think it would be better if we could have like bots that we control from home.
This particular vehicle can be driven manually or by remote control.
