Tactical Systems' LECTOR Robot In a Box is a smaller unit than the HD, weighing eight pounds compared to the 45-pound HD robot. It also has a range of 1,200 feet. The on-board video system can capture about two hours of footage using a pan/tilt infrared video camera that operates in low-light conditions. It can capture images up to 1/2 mile away (line of sight). It can carry a 37mm multi-barrel launcher.
