Robotics Challenge

The Sonoma County Office of Education is proud to sponsor the Sonoma County Robotics Challenge. Now in its 18th year, this dynamic project engages students in grades 4-8. School teams work on challenges designing, building and programming using Lego Mindstorm Robot Kits. Students learn about coding and apply practices from math, science, and engineering as they prepare for events.

Activities span the months of January through May. January is spent building capacity among teachers and volunteers who will work with students at local schools. In early February, challenge events for the year's competition are announced. Challenges are designed for beginner through advanced student competitors. School teams meet once a week from February through April to develop challenge responses. The culminating experience is the Sonoma County Robotics Challenge, where teams come together and compete matching robots and ideas.

What and Where to Buy

Three different robotics kits can be used in the annual challenge competition. One kit features the traditional programmable brick known as the RCX, which Lego discontinued in 2009. It is no longer available for purchase. Another option is the programmable brick known as the NXT. Lego discontinued this version in 2015. A commercial version can still be purchased at some retail stores.

Lego's newest programmable brick is the EV3. Introduced in Fall 2013, this product is growing in use and popularity among schools in Sonoma County.
