Operation example and Caracteristics of the Hydraulic High-Power Artificial Muscle (image) Tokyo Institute of Technology Share Print E-Mail Caption (Left) Demonstration Video : High-Power Hydraulic Artificial Muscle for Tough Robots https://youtu.be/a6mRhuR_g-E (Upper Right) Operation example of developed artificial muscle. (Lower Right) Characteristics of developed artificial muscle. Outer diameter: 15 mm, Maximum contraction force: 7 kN (= 700 kgf), Maximum contraction ratio: 30 percent. The contraction ratio is calculated by dividing the artificial muscle contraction amount by its original length.
