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 Head Lift

The Head Lift
This is my head ski lift.  I attached the skiers by they're heads to go up the lift.  When someone reaches the top, he triggers the sensor to stop the lift so he can get off.  The lift waits for 8 seconds and the starts again.  This lift can carry two skiers.  There are two other lego blocks attached to the lift that stop the lift when they get to the top so the skiers can get back on again at the bottom.  The motor runs on pretend solar power.
