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

Escape Elevator

Once upon a timed there was a princess named Rapunzel. And she had to spend all day and all night living in a very very high tower all by herself. Finally, after growing her hair for years and years, she finally gets to see the prince when he climbs up her hair to see him.

But really, why should she have to wait to grow her hair out when she can have a magical elevator! Built for Rapunzel by Amy, Fatima, and Joshua, this elevator has many features. It's remote controlled: she chooses when it comes up and down, giving her all the power to see who she wants. It comes equipped with an alarm when someone Rapunzel doesn't know or like gets too close, an alarm goes off. And, it has a clever counterbalance to keep it from falling off.
