HAL (Hybrid Assistive Limb)
Cyberdyne, a Japanese robotics company, has developed and is currently selling a human exoskeleton that can allow disabled people to stand up and walk. The company sells both full body and lower body only versions of the exoskeleton. Their exoskeleton is controlled by electrical signals sent from the users brain. A sensor attached to the users legs senses an electrical impulse when the user prepares to stand.
The HAL features a lightweight structure, and has a very similar appearance to Parker's Indego.
