Northrop Grumman-made robot used in Dallas

The robotic device used to take out the gunman in last week’s shooting rampage in Dallas is a Remotec Andros Mark V-A1.

The device, normally used to diffuse bombs, delivered a one-pound payload of C-4 explosives and detonation cord, police said.

The machine is manufactured by Northrop Grumman and cost the department about $150,000 in 2008. Dallas Police Chief David Brown said the plan to deliver the explosives came together in about 15 minutes.

The Mark V-A1  is driven by a human via remote control, weighs 790 pounds and has a top speed of 3.5 mph. It carries a camera with a 26x optical zoom and 12x digital zoom. When its arm is fully extended, it can lift a 60-pound weight. The grip at the end of the arm can apply about 50 pounds of pressure.
