Sadly, Dr. E’s WeDo Challenges and Dr. E’s MINDSTORMS Challenges will no longer be posting new challenges. However, both websites will remain up so that you can continue to access the previous challenges and all of the wonderful submissions. Thank you to LEGO Education and to the Center for Engineering Education and Outreach at Tufts University for their years of support (and thank you to LEGO for their amazing robotics platforms). During the six years of WeDo challlenges and five years of MINDSTORMS challenges, we received almost 1000 submissions from around the world. The two websites had a total of 1266 registered users from 57 different countries. We were truly a global community! We have always been inspired and energized by the creativity and innovation shown by the Dr. E's Challenges community; while new challenges won't be posted moving forward, we hope that you continue doing awesome stuff in your homes, clubs, and classrooms and that you continue to share your projects with the world! Collaborating with all of you has been a joy and an inspiration. Thank you, The folks at Dr. E’s

Burglar alarm in closet


 Hello! We are Antek and Jarek. This is our first time we participate in Dr E Challenge.

Take a look at the video. We will explain you carefully how program for our robot. In the end you will see how it works.
Burglar robot. It's made of one motor, EV3 brick and infrared sensor.



 Infrared sensor is the most important part in our robot. It checks if somebody come to place we want to protect.


See how little LEGO bricks we used! Cool robot doesn't need to have a lot of elements.

    Welcome to Dr E’s! What a sophisticated program for your first submission! Your mechanism for holding and shooting the balls is really clever–and I love your demonstration filmed in the closet!
