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



I chose to share a scene from The Mitten by Jan Brett.  The boy is going to climb the tree and lose his mitten.  I used a send message block to make my crane go up and down.

    We really like your crane design and how you made him go up and down. We also like how you used a little white lego as the mitten. Good Job – 2nd Grade SAGE Group

    Great job Joey – I love all of the details you added and the way you kept working until the timing was just right. Also, I’m glad to see you took the time to figure out how to use the send message block. 🙂
