Abe also revealed plans for a task force to develop Japan's robot industry and to triple the size of the market for the machines to 2.4 trillion yen ($24 billion).
"In 2020 I would like to gather all of the world's robots and aim to hold an Olympics where they compete in technical skills," Abe told reporters.
"We want to make robots a major pillar of our economic growth strategy," Abe was quoted as saying by Japan's Jiji Press agency.
Abe was speaking during a visit to production lines for industrial and care-giving robots in Saitama, north of Tokyo, and in the Japanese capital.
"We would like to set up a council on making a robotic revolution a reality in order to aid Japan's growth," he said.
Abe gave the thumbs up to a bed that transforms into a wheelchair, calling it "easy to use" after trying it out for himself.
Japan, one of the world leaders in robotics, recently unveiled a chatty humanoid robot that its makers say can understand people's emotions.
