banks of LEDs, one white light, the other infrared. The center-front compartment holds a video camera and an infrared camera. Both cameras' images are transmitted back to a handheld LCD screen and remote control console via a single antenna. The image that is transmitted back is controlled by a mechanical switch, thrown remotely inside the chassis by a remote controlled actuator. The motors are controlled the same way that a remote control airplane or car is. The ability to reverse the tread direction on both sides gives the robot a 0 degree turn radius. In 2006, the exterior body was refinished, the antennas were repaired (replaced by a fishing pole) and some of the interior electronics were updated. The robot is simply constructed, with basic electronic controls, and is the same physical design as the current PackBots, it only lacks the digital processor. SWARM is an artificial intelligence research project designed to develop algorithms for swarms of hundreds of individual robots. This project is sponsored by DARPA. PackBot PackBot is a series of military robots designed for situational awareness, reconnaissance, explosive ordnance disposal and other missions. As of 2009, the US military had more than 2000 PackBots that were on station in Iraq and Afghanistan. SUGV iRobot's platform for the United States Army's Future Combat Systems. Warrior Warrior, currently in development (expected deployment in 2008), is a machine that can travel up to through rough terrain and up and down stairs while carrying payloads weighing over . Its potential uses include bomb disposal, battlefield casualty extraction and firefighting. R-Gator R-Gator, a product of a partnership with John Deere Corporation, is a small utility vehicle with a robotics package added. It is capable of autonomous operation including waypoint following with obstacle avoidance, following dismounted infantry and other vehicles and semi-autonomous operation such as teleoperation with obstacle avoidance. Vehicles are currently in production. Negotiator Negotiator is a man-portable civil-response surveillance and reconnaissance robot. Transphibian Transphibian is a man-portable UUV and bottom crawler that autonomously inserts itself into the water and operates in a shallow area. It is designed for mine detection, harbor defense and surveillance. Chembot Chembot is a DARPA-funded prototype of a shape-shifting robot without motors, wheels or any rigid elements. It runs on chemical power and is made using dielectric elastomers, which are extremely flexible and can alter their shape in electric or magnetic fields. Ultimately, the program aims to
