HAL in the wild

Probably you've all seen Cyberdyne's HAL 'assistive limb' device, that in the future will render your biological legs obsolete. That is, if we start using these as casually as these three jolly Japanese roaming the streets with their new externalized skeletons. To me a showcasing of a technology in actual daily use as in this video is always much more interesting and insightful than the usual spotless and clean studioimages. In the evolutionary tree to-be of assistive walkers, I would warmly welcome an four-legged assistive device with dry-adhesive undersurfaces.
