Just thought I'd point this out for Veteran's Day.
This company was founded by the father of a soldier who was killed in Iraq the week after he had requested body armor. It uses off-the-shelf parts and simple hardware to create cheap, highly effective robots to help soldiers on the front lines by detonating IEDs and even carrying wounded. A typical model of robot offered by large corporations for this sort of task costs $250,000. This robot, the LandShark, costs only $70,000.
What have you done to support the military? I know I'm humbled.
