The latest version, released in 2010, dubbed the APA-5 — developed with funding from the Office of Naval Research’s Tech Solutions Program — weighs roughly 20 pounds and can lift up to 600 pounds at speeds of up to several feet per second.
Originally, for instance, when power ascension was more novel, users requested an ascension pace of 10 feet per second. But Atlas found that as soon as you maneuver over, say, more dangerous terrain or over edge of a wall, going that fast could mean crashes and injuries. So for some customers that operate in dangerous terrain, they compensated with slower speeds, but a higher lifting capacity — which was, in fact, beneficial, Ball says. The device can also now be submerged in water for maritime use.
Innovation also occurs at the material level, Ball says. For example, Atlas recently made the switch to more advanced ropes that have higher tensile strength, with smaller diameters. “To carry a 200-foot section of rope was up to 15 pounds; now it’s closer to 8 pounds,” Ball says. “We’re always trying to find better ways to accomplish things.”
