People with lower extremity disorders who are used to making their way around in a wheelchair might have the chance to take a stand—and a walk—with the Phoenix exoskeleton. This modular mobility device is composed of two leg braces that provide structural support. Each brace is equipped with a pair of hip-level, battery-powered motors that propel the user’s movement, while an Android app tracks gait data over time to monitor improvements. What makes the Phoenix so different from its predecessors is its spartan design, born from biomechanics rather than the practices of industrial robot construction and the benchmarks of military contracts. Phoenix has been built not to defeat obstacle courses, but to allow someone who is paraplegic and otherwise bound to a wheelchair to stand, sit, and walk on a level grade at 1.1mph.
