This anti-mine device contains a GPS so it knows where it has been and the basic core is high enough to avoid damage by mines designed to blow off human legs.
“So, as it moves the spikes get blown off, but the center stays intact,” Hassani said. “It can withstand up to four explosions before it loses too many of its legs to carry on.”
Future models will be remote-controlled and have metal detectors so mines can be mapped even if the device has lost a few spikes and can’t trigger a mine.
