To many people, "military robots" mean unmanned aerial or ground vehicles. Many military robots fit these categories, but some go way beyond this definition.
For example, we've reported before on Boston Dynamics robots that mimic human, animal, and insect movements. The Georgia Institute of Technology's Scalybots mimic a snake's movements. Designers of these tactical robots are trying to come up with small machines with rugged design, multiple data collection and communication methods, long battery life, the ability to negotiate rough terrain, and, in some cases, lifting and grasping capabilities. The goal is to go where humans can't without risking their lives.

The Machine Lab's MMP-30 Mechanical Mobile Platform is used for explosive ordnance disposal in Iraq. It weighs 50 pounds (including control unit), measures about 23 inches long when collapsed, and can be carried in a backpack. Its pan/tilt color infrared camera has 180-degree pan and 150-degree tilt. The robot also sports a color, wide-angle gripper camera and a color, wide-angle rear-facing camera. The four-axis arm has a 20-inch reach and can lift five pounds at full extension.
