Unpowered exoskeleton for human walking

Supplementary video from the paper “Reducing the energy cost of human walking using an unpowered exoskeleton“ authored by Steven H. Collins, M. Bruce Wiggin & Gregory S. Sawicki, published in Nature 522, 212–215 (11 June 2015) doi: Abstract: With efficiencies derived from evolution, growth and learning, humans are very well-tuned for locomotion1. Metabolic energy used during walking can be partly replaced by power inp
