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.
The folks at Dr. E’s
The Knights are at the castle door and they want to get in and take over. But they need some help to get the door down. Here comes their new invention, a Cotton Ball Launcher!!!... See how it can break down a whole Castle door!!!
Two motors and separate programming for each motor is used in this. One to launch the cotton ball launcher and another to bring down the wall when the cotton ball hits it. The launcher flings the cotton ball and comes back to original position and a knight's helper stands by to load it again..
The Knights are here to take over the castle and they brought some help to bring down the front door..
