The sense of touch is generally measured by a sensor that can translate a pressure upon it into a small electrical signal. Shutterstock

It’s not easy to give a robot a sense of touch

Our sense of touch lets us know how hard or soft something is, how solid or pliable it is to handle. That’s an important skill if you want robots to handle things safely.

We need robots that can improvise, but it’s not easy to teach them right from wrong

Robots have already learned to cheat when playing games. How do we teach them morals if we want them more involved in our everyday lives?

Robot sculpture, coming to a gallery near you

Artists invented the word ‘robot’, but now robots are becoming artists, or at least assistants, themselves. As robots get smarter, artists will find more and more uses for them, particularly in sculpture.
Surgeons admit to unintentional mistakes when performing delicate surgery.

Surgeons admit to mistakes in surgery and would use robots if they reduced the risks

Surgeons say minor unintentional damage can happen during surgery, and much of that goes unreported. They say they would be prepared to use robotic tools if they could be shown to help.

How to backup life on Earth ahead of any doomsday event

NASA says there are ten “potentially hazardous” asteroids close to Earth. Good reason to make sure we have a backup plan should any catastrophic event wipe of much of life on Earth.

How to make a driverless car ‘see’ the road ahead

For a driverless car to be safer than one driven by a person it must know what’s going on around it. But making a system that can “see” is a challenge for tech companies.

Driverless cars, just imagine how we could use them

When you don’t need a human to drive a car there are plenty of things you can do with such a vehicle.

The winners and losers in the race for driverless cars

It’s a race that’s pitting the motor industry against tech giants and even the ridesharing company Uber. But what will be the impact when driverless cars take to the roads?

Do wind vent holes in banners make a difference? We used a wind tunnel to find out

Attend any ANZAC Day parade and you might see people carrying banners with holes cut in them. They’re supposed to cut any drag or wind resistance but do they do any good?
