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

At Another Man's Pie! Nikita has chosen Russian proverb that sounds like "Na Chuzhoy Karavay Rta Ne Razevay". The English translation is "Don't Gape Your Jaws For The Cake Is Not Yours" (or related proverb in the title) meaning respect other people's properties. He has imagined a hungry alien monster trying to eat a cake on our planet. There is a hidden motion sensor that makes the monster stop in front of the cake. And it is a talking cake!
