Japan’s robots: The future for intelligent machines?
All week on 5 live and across the BBC, we're taking a look at how intelligent robots are changing the world we live in.
Peter Allen has spent a few days in Tokyo finding out what's happening at the cutting edge of the robotics world, and what the future might have in store.
He started his trip at a Tokyo convention centre, where amateur robot engineers showed off their latest inventions. Expect robots who drum, moving flowerpots and a baby-sitter like no other.

He also ran into this pair of fighting robots.

Robot fight! Japanese machines take to the ring
Two robots do battle in Tokyo. Which will emerge victorious? Peter Allen commentates.
On Peter's next stop, he met "Pepper": a so-called "companion robot" that can read human emotions. Yusuke Abe, a developer at SoftBank robotics, explained what Pepper could do, and why it was proving popular in Japan.

The robots so far looked like robots, but what about the ones with more human-like features?
At the National Museum of Emerging Science and Innovation, aka the Miraikan, he met Erica: a humanoid robot that looked and sounded like a real person.
He had some tough questions for her - to see if she could "think" like a human too.
