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

24 piece or 10 piece?


 This is a challenge to build a car with Mindstorms EV3 with only 24 parts or less.  Here I show 3 different cars - on with 24 parts that can drive with a remote control, 21 parts that can drive with programming and a 14 part car that can drive only straight...and just for fun made a 10 part car that can go only straight and possibly scratch the surfaces it drives on....(not recommended)

    What a wonderful video–great job showing increasingly simple models and what each is capable of! Hope your family doesn’t mind the scratched table…
