Robotics Challenge 2020

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.

Challenge Event Robots

Lego Mindstorm Robots are used by event competitors. This product was selected because it has a programmable brick, open design & construction options, a variety of sensors, learning materials and programming applications that are accessible to beginning through advanced users. An overview of these robots is offered here:

  • Lego Mindstorm EV3 This is the most popularly used robot set among challenge event competitors. Introduced in Fall 2013, this kit has over 400 Lego elements, including a programmable brick, learning materials, and apps that can run on computers, tablets and Chromebooks.
  • Lego Mindstorm NXT Introduced in 2006, this set was discontinued in 2015. A commercial version can still be purchased at some retail stores. The NXT series is still being used among competitors for beginning and advanced events.
  • Lego Mindstorm RCX This set was introduced in 1998 and discontinued in 2009. It is no longer available for purchase. The software for the RCX programmable brick will not run on newer computers and most schools use this set only for beginning level events.
