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

Girl’s Catapult

Hello again!
We are Malina and Marusia. This time we created catapult.


Look at the basket for batteries under the turntable. As we said - heavy batteries made our robot more stable. Without it - catapult jump!


Have a look how catapult works!
Our remote contains two sensors - color sensor and touch sensor.


Our catapult. If you have seen our robot that we created on Art Show Challenge you can noticed we are quite experienced in building catapults.
See you nex time!
       Malina and Marusia

    Another awesome project! Your aiming mechanism is terrific–and beautifully explained! (And I’m glad that you were able to find another use for Frankenstein.)
