Many workers in hazardous environments and other worksites must regularly perform physically exhausting tasks while wearing heavy protective gear, overexertion from which can sometimes result in debilitating physical injuries. To help increase worker performance and reduce strain on potentially injury-prone joints, we are investigating how to leverage ankle, knee, and lower back exoskeletons to provide targeted assistance during a variety of walking and lifting tasks. To measure the effect of each of these exoskeletons on the wearer, we are collecting metabolic, EMG, and motion capture data across a battery of lifting and walking tasks similar to those these workers would face. The results of this work will help us to determine which exoskeletons are most useful for these kinds of tasks right now, and will further inform our development of more intuitive and effective exoskeleton control strategies down the road.
