Exoskeletons have received some attention over the last years (some with a clear application area in the army), e.g. Robot suit HAL and the BLEEX Project.
Honda showed now an interesting exoskeletons as walking aid. It is called „computerized leg device“ or „walking assist device“ and there is an short movie on youtube and it is designed to help people walk. The application areas are probably broad – I expected mainly in care and rehabilitation, but looking around there seem to be more application domains…
