Biological characteristics have long been overlooked to make human-like robots. It is not mandatory to follow every human muscle to create a functional humanoid. Following or replicating every detail of biological strings will simply complicate the process. This special field is being observed in Tokyo University’s JSK Lab. Scientists of that lab have developed a robot using their observations which can be called the world’s most advanced and perfect Robot at least anatomically.
Scientists are working hard at the JSK lab for a decade and trying to develop more complex but effective musculoskeletal robots. Kenta was first of the long line of robots built by them. They developed Kotaro in middle of 2005, in 2007 Koijiro was released by the same team followed by Kenzoh in 2010. Their key features are Legs with 25 internal artificial muscles: replicating major 160 muscles of the human.
Another important thing other than muscle is bone structure. This element was taken into consideration with an extra emphasis while they were creating Kenshiro. Its skeleton was forged with aluminum; an element which will stand still without breaking even under extreme stress. Comparing to previously used substance, this is a wise choice. Kenshiro’s Knee joints are supported by artificially made ligaments and patella. Above discussion was just some simple concepts to be taken into consideration while you try to compare it with any other Robot.
