ATLANTA — One of the newest weapons in the Gwinnett police arsenal is the bomb squad’s robot, a metal marvel capable of climbing stairs, dragging a person, disarming a bomb, testing for chemical agents and photographing a crime scene, among other things.
The Remotec ANDROS F6A was purchased this year with a $182,000 Homeland Security grant.
It is the department’s second such robot, so SWAT officers and bomb technicians can now respond to multiple calls at once.
Officer Kevin Moller, a bomb squad technician for the Gwinnett County Police Department, said the robot is “pretty much a workhorse” --- used whenever possible in almost all the department’s SWAT and bomb squad incidents. It is often sent to evaluate a crime scene and make sure it’s safe before officers are sent in.
“You don’t want a human being put in harm’s way,” Moller said.
The approximately 480-pound robot, made largely of aluminum, runs on a set of four removable pnuematic wheels and a track similar to the ones on tanks. The tracks help it navigate rough terrain and ditches, climb stairs and power over other obstacles.
Among the robot’s other features:
* The robot is powered by a rechargeable battery and is remote-controlled. It can only travel about 5 mph.
* Two cameras mounted on the robot allow for color and infrared surveillance photographs and video.
* A microphone and speaker mounted on the body allow police to negotiate with a barricaded suspect and record the dialogue.
* The motorized arm is capable of gripping an object, picking it up and dragging it away. “It basically operates like a human arm,” said Moller. It has shoulder, elbow and wrist components that let it retract and rotate with dexterity.
* A fiber-optic cable means the robot is hard-wired to send audio and video it records back to officers waiting in a safe zone.
The robot can be controlled by radio frequency, or a cable cord can be tethered to a remote.
