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

Oakwood Can Do! Submission 2017

This is the submission from Oakwood Middle School for the Can Do! challenge! It’s pretty straightforward – all you have to do is push two buttons to empty your can. (P.S. I know the can didn’t have anything in it. Our teacher did not trust us with liquid and I don’t blame her.)

Just a student from Oakwood Middle School. Considered a genius by some. For some reason I'm not aware of.

    What a clever contraption! The mechanism for holding the can is impressive–simple and effective (blooper notwithstanding). Nice job demonstrating your mechanism and program, too!

      Thank you! You have no idea how much it means to me that people see what I do and think that it matters in some form. Again-thank you so much.
