The Dr. E's WeDo Challenges website provides an online space where different monthly contests inspire children to design, implement, and share their solutions with a worldwide community of like-minded robotics enthusiasts. Appropriate for doing at home with young children or in after-school clubs, teachers can also bring the challenges into the classroom to help develop building, programming, or other content-related skills using the LEGO® WeDo platform. Dr. E's Challenges encourage learners to develop creative technical solutions to open-ended problems, and to share their work online inspiring others around the world.
