The micro:bit Global Challenge – the winners!

We had hundreds of amazing entries to the micro:bit Global Challenge from all over the world. Thank you to everyone who entered and for all the effort you put in to your fantastic devices.

What is the Global Challenge?

In 2015, world leaders came together to decide on a series of "global goals" to build a better world. We challenged students aged 8-12 across the globe to consider how these goals could change the lives of themselves and others, and to design solutions to these goals using the micro:bit. Supported by a number of delivery partners, our Global Challenge competition saw hundreds of entries from a diverse range of countries cultures, and backgrounds. Learn more about the Global Challenge here.

We are excited to announce the winners of the Global Challenge 2018!


Meet the judges

Europe

Team Veliki, Croatia

Team Veliki created 'spine:bit' - a device that tells you if your posture is incorrect. The micro:bit sits in a lightweight backpack and detects when the wearer is sitting incorrectly and sets off an alert.

The judge said:

“The winning entry addresses a really common problem of sitting in an incorrect position which affects not only the spine but also our organs and overall health.

The implementation is simple yet the device works really well... it can be adopted on all people regardless of their age, and it has an active feedback for the user”

Asia & Pacific

Food Waste Watchers, Singapore

The Food Waste Watchers designed a device that will help to reduce food waste. The device measures the amount of food that is being thrown away and if it’s more than 30g it displays a message to remind them not to waste so much food! The team installed the device in their school’s food waste bin and after it was piloted, they reduced the amount of food waste in the school by 50%!

The judge said:

“The use of a micro:bit coupled with a weighing sensor and an LED to monitor food wastage is a very original and innovative idea. It has been proven to work well… and can be adopted by other schools”

Africa

Joseph Adewole, Nigeria

Joseph designed a system that detects the temperature of students in a class and lets their teacher know. He designed the device so that students can be treated quickly if they are ill and therefore don’t miss too much school.

The judges said:

“...the students’ body temperature can be used as an early warning system for proper attention to avoid sickness-related school misses, and to avoid the spreading of sickness within the classroom. High attendance to school would increase the access to information provided by the teacher in the classroom.”

North America

Elizabeth Gatten, United States of America

Elizabeth looked in to Safety and has designed a low cost home security system using the micro:bit. The system detects movement and emits a high pitched noise and displays flashing lights to scare burglars away or alert the house owner.

The judge said:

“Elizabeth’s project is creative... and impactful. (Her) description is well documented and detailed so the device is easy to recreate.”

Middle East

Zayd Nashed, Saudi Arabia

Zayd has created a Doctor robot that helps kids with an illness such as asthma. The robot gives the child medicine on time, contains a dust sensor to alert the child to a dusty environment, and interacts with the child through its facial expressions!

The judges said:

“Zayd has showed an advanced knowledge of electronics and mechanics... The robot is able to move, rotate it’s arm and show emotion on his face depending on the environment. While most robotics implementation are for industrial use, this concept demonstrates how robotics could be use to have an impact in our daily life.”

Latin America

Kathellen Lima, Brazil

Kathellen noticed that a lot of rubbish was thrown into the rivers in her city and this is was causing problems for people who live nearby. She has designed a ‘anti-trash buoy’ to help keep the rivers clean. The micro:bit uses noise and lights to alert people when rubbish is thrown in the river.

The judge said:

“Kathellen has properly identified a problem in her community, found a reasonable solution, and implemented it nicely.... the coding is short and correct, and the device created is ingenious.”

The Global Challenge will return... do your :bit coming soon!
