1Researchers in Japan have developed a robot capable of peeling a banana without crushing the fruit inside.
2While the two-armed machine is only successful 57 percent of the time, banana peeling points to a future where machines could do more sensitive, skillful kinds of work.
3Video from researchers at the University of Tokyo showed the robot pick up and peel a banana with both hands in about three minutes.
4Researchers Heecheol Kim, Yoshiyuki Ohmura and Yasuo Kuniyoshi trained the robot using a "deep imitation learning" process.
5In this training, they showed the banana-peeling action hundreds of times to the robot to produce enough data for the robot to learn the actions and copy them.
6In this case, the banana reached its success rate after more than 13 hours of training.
7While the experiment requires more testing, Kuniyoshi believes his method can teach robots to do different simple "human" tasks.
8He hopes the better-trained robots can help with Japan's labor shortage problems, particularly in food-processing factories that currently depend on human workers.
