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

Peanut Butter and Jelly Maker

Description

My name is Garrett. Me and my brother Shay built a robot that makes peanut butter and jelly sandwiches. All you need is to put some jelly and peanut butter on a plate, get the bread and let the robot do the work.

    Garrett and Shay — Congratulations on producing such a great prototype! I like the use of two motors — one for an arm and one for a wrist. You tuned your system well such that it scooped up the jelly and managed to get it onto the bread. I am glad that you shared with us some details about your toaster project. Making robots involves making many prototypes. Keep up the great work!
