Tanaka Hisashige was one of Japan's most revolutionary inventors and engineers during the Meiji Period. He is known for his company, Toshiba. One of his most notable works are his karakuri dolls which he made when he was still 20 years old. These dolls were powered by springs, pneumatics (gas or air pressure) and hyrdraulics (liquid pressure). The dolls are capable of complex movement. These dolls can also shoot arrows! The fun part is the dolls were programmed to miss one of four shots and do happy motions when it can hit the mark and sad motions when it can't. At age 21, he performed all around Japan.
