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

Ramp Climbing Car


 This car that I have made can climb a ramp of about 55 to 60 degrees.
It consists of two motors and no sensors.
The speed of the car it changeable using the top and bottom buttons on the brick
The problem with my car, is grip. The car can climb most angles if it can grip the ramp


 A video of my car climbing a ramp with a rug on it


 This car has a ratchet built into the drive gears to stop the car rolling backwards down the hill.


 This is the program i run on the car
