The A.F.A. exo-suit is a powered exoskeleton suit designed to increase the performance of firefighters in high-rise fire situations. This suit is capable of carrying loads up to 91kg and is strapped over the firefighter's clothing. By transferring its weight and load directly to the ground, the exo-suit relieves firefighters from bearing the weight themselves. It serves as an assistant equipment, utilizing new technology to enhance carrying capacity and personal mobility, ultimately achieving more effective firefighting in the future, specifically by the year 2030.
The A.F.A. exo-suit is constructed with titanium and covered with meta aramid fiber. It incorporates actuator and sensor units in each joint, along with servo motors, structure wheels, bearings, and capstan wheels. The foot of the exo-suit features a load distribution sensor, a rubber pressure tube filled with hydraulic oil, and a main exoskeleton foot structure. The weight of the firefighter and the load they are carrying is transferred onto the pressure tube and measured by the sensor.
Technical specifications of the A.F.A. exo-suit include adjustable dimensions of width (600mm), depth (430mm), and height (1600mm), with an approximate weight of 23kg. It is powered by a lithium-polymer battery, providing a continuous operation time of approximately 2 hours.
The A.F.A. exo-suit is operated by strapping it over the firefighter's gear. Once equipped, the exo-suit provides supplemental muscle to aid performance in walking, running, and carrying. This significantly reduces the lead time to the fire ground, allowing firefighters to quickly respond to emergencies. In case of any malfunction, an emergency release system is incorporated into the exo-suit. Firefighters can simply pull off the bars on each side of the thigh, causing all the joints of the suit to disassemble automatically.
The A.F.A.-Powered Exo-Suit for Firefighter project was initiated in March 2014 at Monash University and completed in 2015. Extensive research into high-rise fires and firefighter gear was conducted, followed by brainstorming, body storming, benchmarking, user scenario development, and design exploration. The final stages involved design refinement, CAD modeling, and the creation of 1 to 3 prototypes.
The A.F.A.-Powered Exo-Suit for Firefighter has been recognized for its outstanding design and innovation. It was awarded the Silver A' Design Award in the Futuristic Design category in 2016. This prestigious award is given to designs that demonstrate exceptional expertise, creativity, and technical characteristics. The A.F.A. exo-suit showcases remarkable excellence and introduces positive feelings of amazement and wonder.
