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

Asteroid Xbug

Insectarium Description
This creature is from Asteroid X.  It stays in one place and waits for prey to come to it.  When a bug comes close to it, its motion sensor eyes detect it and open its mouth and catches the prey with its magnetic tongue (because the prey is made out of metal paper clips).  Then it starts munching the bug.

    Great job with this project! (It looks really complicated…) I loved the way it ate its prey. Obviously very well thought out. Keep up the great work!
