Nothing transforms scientific gurus into excited SciFi geeks quicker than the mention of a robotic exoskeleton. Iron Man, RoboTECH, Exosquad, Starship Troopers (the book), Neon Genesis Evangelion, Aliens and a thousand other pieces of entertainment have convinced us of one thing: robotic suits = awesome. Professor Yushiyuki Sankai, founder of the Japanese robotics company Cyberdyne, is unabashedly a fan of science fiction, and he now sits on the cusp of bringing that awesomeness into our everyday lives.

Cyberdyne has developed Robotic Suit HAL, a 50 lb exoskeleton that easily fits over an adult body and augments strength and stability. HAL, short for Hybrid Assistive Limb, completely supports its own weight and balances itself, allowing the user to move freely and lift objects two to ten times heavier than he or she could alone. The glowing discs in the diagram are actually motors providing the necessary forces. Its rechargeable 100 Volt ACDC power source will run for five hours for normal activity. Sensors along joints read motor neuron impulses telling HAL when and how to move. No complicated controls are necessary. This means that anyone can strap on HAL and be walking about in just a few minutes.
