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



We designed a robotic chicken coop.  Some of our group are chicken keepers and realized that it's hard to clean the chicken poop!  So, we designed a moving coop to spread the poop and fertilized the farm.  It was very hard to build.  We combined the design for a frog and added wheels, then we built a coop for the chickens and added it to the top of our moving brick.  We made some paper chickens and added them to the coop, and then programmed it to move slowly across the LEGO farm.

    What a clever idea! I’m sure anyone who keeps chickens would like to have one of your robotic coops. Love your chickens, too!
