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

Smart Hat

Goal: A hat should do more than cover your head! Use WeDo to make a smart hat. It could fan you to keep you cool or greet passers-by when you go for a walk. 


Start date: November 1, 2014
Due date: November 30, 2014

Rules: Use a WeDo motor or sensor (or both) to make the smartest hat in town. You can only use the sensors and motors from the WeDo kit. However, you are welcome to use multiple WeDo kits, additional LEGO pieces, and non-LEGO materials. Tips for using WeDo motors can be found here: Design for Motion. For tips on using sound with the WeDo program, check out this snippet: Programming Sound.
