Technology:
Motomu Nakashima of Tokyo Institute of Technology and his research team members developed
a humanoid robot that can swim by itself without receiving instructions from
outside. Named SWUMANOID, the newly developed robot is 89 cm tall and weighs
about seven kg. It has a total of 20 build-in waterproof resin motors. It can swim
freestyle, butterfly, and backstroke.
It
swam freestyle about 8.5 m at a speed of 0.23 m per second in a swimming pool
without stream. That is, it can swim 25 m in about 108 seconds. If the robot is
built as tall as and as big as a human, it can shorten the time to half mathematically.
It is expected to help the analysis for faster swim and the development of swimwear,
not to mention that it can be applied for lifesaving. Prof. Nakashima plans to
put it into practical application and sell it for one to two million yen in two
years in alliance with private companies.
