Abstract
The use of the McKibben artificial muscle has opened the way to the introduction of "muscle suits"-compact, lightweight, reliable, wearable "assist-bots" enabling factory personnel to lift and carry weights greater than conventionally possible. Since low back pain is one of the most serious issues for the manual worker, we focus on developing sacroiliac support. In this paper, the concept, a new mechanical structure and effect of the sacroiliac support system is shown. From the experimental result to keep forward tilting posture with load indicates our system is very effective for keeping forward tilting posture and it becomes clear that more than 75% reduction of muscular power is realized.
