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

A Minute on Your Lips


 Our proverb is:  A Minute on Your Lips is Forever on Your Hips.  Our proverb means that some foods are very tasty and make us happy for just a minute, but their unhealthy fattening qualities can affect us for our entire life by causing us to gain weight.  We built a doughnut shop to represent delicious, tempting, and fattening food.  We then created a giant donut that our mini fig could rise up from. In order to have our figure rise from the doughnut, we built a crane using a worm gear.  When the worm gear turns it pulls our figure up from the doughnut.  We wrote a simple program that turns our motor and then the worm gear.

    We really like how you explained your proverb and how your structure moves. We would have like to have heard some kind of sound in the background like sound effects or someone talking. Overall, great job your ideas are very creative.
