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

The Big Skeleton Spider

Insectarium Description
This Big Skeleton spider was built by Álvaro (12) and Jaime (12). 
Once upon a time in a wide forest, there was a big skeleton spider that loved to eat people.
But two terrifying warriors came to destroy the monster. They tirelessly fought againt the spider, till they finally beat it and the Big Skeleton Spider never moved again.
Very good job guys. Congratulations.
