The Berkeley Lower Extremity Exoskeleton.

The article features the Berkely Lower Extremity Exoskeleton, the first functional load-carrying exoskeleton. It can walk at the average speed of 1.3 mls while lifting a 34 kg load. The 4 basic technologies related with the exoskeleton: the architecture design, control schemes, the body local area network, and the series of on-board power units were tackled. An overview of one of the control schemes is also given with the analysis that extends the definition of a system's sensitivity function.
