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

Mixer bot for food coloring

Video
Oscar is a 6-yr old Chinese boy in Shanghai. He started to play with Lego Wedo set a few months ago and completed most of the guided building. This is the first set he initiated, designed and built almost by himself. Well, I helped him to refine the design and give him some hints during the building. As his father, I am proud to record this video to show his first submission. 

btw, he can only speak just a little English. So he spoke Chinese in the video and I added subtitles in Enlish. Sorry for the inconvenience.

    A speedy and effective mixer! Great job!
    Thank you for providing subtitles. However, we are happy to see submissions in any language, with or without translations. We have had submissions in many languages other than English.

    It’s wonderful 🙂 it truly is a miniature mixer and it seems to be working well – you should check if it could mix a small portion of simple icing (powder sugar, food coloring and maybe a few drops of water) – I actually think it might be able to. Such a great job – I can’t wait to see what he will come up with for future challenges.
