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

Milkshake Test for RoboWisk


We tested RoboWisk preparing a MilkShake. Test our solution for the Wisk! Gearing up to increase motor speed and tilt sensor are used. WeDo base + extesions set needed. Family team, Venice area, Italy

    That was an amazing contraption mmm. That is a very advanced machine for your age and has a very interesting turning system. By the way you might want to add powder before milk it will mix much better and have a more noticeable difference. Great job!

      The concrete possibility to mix something was the key for the children to challenge and to speak english (ve are italian).
      Thank you

      Thank You for your welcome
      1) RoboWisk has only two speeds (gearing up was necessary to increase the number of rotations per single speed)
      2) The milkshake had to be exquisite… even though I needed some time to drink it all
