Meet the robot scientists in Japan - and other bots with jobs

A university in Japan has just opened a brand new science lab with a difference... it's run by robots.

There's no human staff at the Institute of Science Tokyo's lab - instead, 10 robots carry out all the medical experiments.

This includes a special robot called the Maholo LabDroid, which already helps out at a hospital in the Japanese city of Kobe.

But what about other bots around the world - what kind of jobs do they do?

Scroll down to find out more about other robots giving humans a helping hand, and let us know what you think in the comments below.

Gabi the robot has just become a Buddhist monk in a special ceremony at Jogye Temple in Seoul, in South Korea.

A monk is a person who devotes themselves to religious worship and often lives in temples or monasteries.

Footage shows the robot wearing robes, prayer beads and placing its palms together and saying prayers.

Meet Valkyrie, the humanoid robot designed to help Nasa on space missions.

Valkyrie stands at 1.8 metres tall and weighs 125 kilograms. It was built by Nasa-JSC in 2015 and was delivered to the University of Edinburgh for testing and research in 2016.

Researchers hope Valkyrie can be trained to complete important tasks in environments that would be too dangerous for humans, both in space and on Earth.

For example, Nasa hopes to send Valkyrie to the Moon and Mars, to work at the long-term worksites and villages that are planned be built there as part of the Artemis missions.

There are tens of thousands of robot waiters working in cafes and restaurants all over the world, like this cat waiter called BellaBot, which has been built by the Chinese firm PuduTech.

BellaBot has four trays and is capable of holding up to 10kg of food. It also has a screen to show different facial expressions.

It meows when it arrives at tables to encourage customers to pick up their food and looks happy when people rub its ears, but it gets angry if they pet it for too long - it has got a job to do after all.

If you find going shopping at your local supermarket a bit boring, then you might find these delivery robots to be up your street.

They've been created by Starship technologies and can deliver groceries, parcels and takeaways to people living in the town.

The robots are fully autonomous, which means there isn't anybody controlling them in real-time, and they find their way by themselves.

Each one is fitted with a 360 degree camera to help it to navigate and not bump into people or things.
