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

Traveling recycling bin by M.E. and Cordelia


 You don't need to go in search of a recycling bin--this bin will come to you! Cordelia and M. E. have made a recycling bin that drives around, controlled by two touch sensors. When the bin is empty, it says "Recycle." When items are placed inside, it switches to saying "Full."

    What a great idea–I can never find a recycling bin when I need one! Your use of a sensor to detect and respond to items in the cup is really clever.
