Here's a video demonstration of the
Warrior 710 by iRobot, with an
APOBS (Anti-Personnel Obstacle Breaching System).
It's a robot for destroying anti-personnel mines used in the military which is capable of destroying bombs stuck in the sand at a distance without damaging the robot.
The idea is simple: the Warrior 710 launches a rocket which pulls a rope packed with explosives onto a risk zone and then detonates the mines to clear the terrain.
A parachute at the end of the robot is used to limit the distance it is thrust out and is sufficiently safe to not damage the robot.
