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

WeDo Pet

Goal: Everyone needs a pet, but not everyone can have a live one. Make a WeDo pet instead. Use a WeDo sensor and motor to make the pet respond to you in some way. A puppy that wags its tail? A kitten that comes when you call it? A tarantula that twitches when it sees food? Create the pet you’d love to have. In your submission, be sure to tell us your pet’s name! 


Start date: January 1, 2015
Due date: January 31, 2015

Rules: Use a WeDo motor and a sensor to make a pet that responds in some way. You can only use the sensors and motors from the WeDo kit. However, you are welcome to use multiple WeDo kits, additional LEGO pieces, and non-LEGO materials. Tips for using WeDo motors can be found here: Design for Motion. For tips on using sound with the WeDo program, check out this snippet: Programming Sound.

Dog friends

 A Lego dog is waiting for its Lego pet friend but its is sleeping. The pet is activated by a microphone when Jofre or Guillem speak. First, it is sleeping, waiting for a sound. After hearing a sound, it walks until the distance sensor detects a nearest object. Then it stops, says “whow whow” and […]
