Each robot contains a small computer and has two wheels, which can allows it to be driven forwards and backwards and turn 360 degrees.

The youngsters were shown how to control them using a simple programme on a laptop computer.

An ultrasound sensor in the robot lets it know when there is an obstruction nearby, allowing it to get around an obstacle course.

The robot also has an “eye” at its front containing a light sensor, which means it can perform tasks such as following a white line drawn on a dark desktop.

The pupils were able to have a bit of extra fun with the robots by having them do some hip-hop dancing.

Rowantree’s depute head teacher Liz Crawford said, “We are delighted to welcome the Generation Science tour to the school.

“The Lego Mindstorms Challenge show is an excellent way of engaging children and making science fun and enjoyable.

“It also reinforces science concepts and introduces the children to new ones using a hands-on, practical approach, which the school can then follow up with general discussion.”

Simon Gage, director of the Edinburgh International Science Festival, said, “The programme of events is a vitally important way of helping children, parents and teachers grasp and get excited by the true magic and meaning of science.

“We give school children the tools and confidence to make informed lifestyle choices about health, food and work, and teach them how to sustainably use our planet’s resources.

“The programme is incredibly varied and exciting, so we really hope pupils will be inspired to become more involved in science both now and in the future.”
