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

Box with a surprise

Kacper likes to surprise everyone. He had an idea to create a robot which combine surprising with other people curiosity.

Would you open the box if there was an inscription saying "Open me"? "Otworz mnie" is that.

The mechanism looks a litte bit complicated but for Kacper it was a pice of cake.

The most important part - infrared sensor. "Without it catapult would not know when to shoot" Kacper said.

And the program - it doesn't look so complicated, does it? Simpe solutions are the best.

    Wonderful idea! How can anyone resist a box that says “Open me.” I love your spirited demonstration of how the box works.

      Sorry, voting for the October challenge has already closed. Voting runs for one week after the end of the challenge. (The good news for you is that Box with a Surprise was the October winner!)
