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 Car

Goal: Keep it simple! Build a working MINDSTORMS car using as few LEGO pieces as possible.

Your finished car must be able to complete the following driving test without falling apart: drive forward for two seconds, backwards for two seconds, spin right for two seconds, spin left for two seconds.

Start date: March 1, 2017
Due date:  March 31, 2017

Rules:  In your submission, tell us how many LEGO pieces you used. (Every item counts as a piece–EV3, motor, wire, hub, tire, axle, beam, connector, etc.) Better yet, include a photo or list of the pieces you used. Also, show us a video of your car successfully performing the driving test.
In addition to an NXT or EV3, you may use sensors, motors, and pieces from the NXT or EV3 kits. You are also welcome to use multiple MINDSTORMS kits, additional LEGO pieces, third-party sensors, and non-LEGO materials.
