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 book that we are sharing with you is Diary Of A Wimpy Kid Dog Days by Jeff Kinney. The scence we are showing you is Greg shooting dirty landry into the basket. Sometimes he makes it sometimes he dosen't, but he usually misses it.

    I really love this robot! What a pitty I don’t have one like this at home! Very interesting presentation – now I know everything about your construction that I have to. Program is pertect! You had to spend lot time testing your robot. Great job!

    Nice job explaining your creation. I know that the laundry is supposed to miss the basket most of the time, but it looks like you built a pretty accurate shooter!

    Great job guys – you did a great job presenting your scene. I like how you used a tire for your hoop and I especially like how you kept modifying your program and scenery to try to help improve your character’s shooting accuracy. 🙂
