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

“I can read” trophy


Pavlinka just has learned to read - and she created a trophy for everybody who likes to borrow books from a library.
The first step is to reach the library by the elevator, because our local library is on the first floor. Pavlinka's elevator is based on a system of pulleys and belts combined with the motion sensor (that stops the motion of the elevator, of course).



The second step is to read a book. Pavlinka created a smart book. After you read a page in the book and move by the joystick, the cat agrees with you that you have red the page correctly. The motion of the cat's head is controlled by a joystick. An important part of the joystick is the tilt sensor. After moving by the joystick, the cat starts to agree with you.




Enjoy the video!

    A trophy for learning to read is a lovely idea. Your elevators to the library are so clever! And your book with the moving and mewing cat is fantastic! Wonderful job!

    Hello…reading is very important and it is great that you created a trophy for this. I love your elevator using pulleys and belts. Wow you even have two separate cabins that move in opposite directions. Using the motion sensor to stop the elevator is very clever. Well done creating a joy stick with the tilt sensor and using this to control the cats head. Thanks so much for sharing.
