Firefighting Robot Presented at Naval Tech EXPO

Scientists unveiled a firefighting robot prototype Feb. 4 at the Naval Future Force Science & Technology EXPO, revealing details about its successful demonstrations last fall.

The Shipboard Autonomous Firefighting Robot (SAFFiR), sponsored by the Office of Naval Research (ONR), walked across uneven floors, used thermal imaging to identify overheated equipment, and used a hose to extinguish a small fire in a series of experiments Nov. 3-5, 2014 aboard the USS Shadwell, a decommissioned Navy vessel.

Developed by researchers at Virginia Tech, the two-legged, or bipedal, humanoid robot is helping ONR evaluate the applications of unmanned systems in damage control and inspections aboard naval vessels, supporting the autonomy and unmanned systems focus area in the Navy’s Science and Technology Strategy.

Dr. Thomas McKenna, ONR program manager for human-robot interaction and cognitive neuroscience, said:

We set out to build and demonstrate a humanoid capable of mobility aboard a ship, manipulating doors and fire hoses, and equipped with sensors to see and navigate through smoke. The long-term goal is to keep Sailors from the danger of direct exposure to fire.

SAFFiR stands 5 feet 10 inches and weighs 143 pounds. The unique mechanism design on the robot equips it with super-human range of motion to maneuver in complex spaces.

Sensors, including infrared stereovision and a rotating laser for light detection and ranging (LIDAR), enable the humanoid to see through dense smoke. It is programmed to take measured steps and handle hoses on his own, but for now, takes his instruction from researchers at computer console.
