Ohio 4-H Youth Development

Ohio State University Extension


Robotics 1 with EV3

In this exciting first-time robotics project, youth use the newest LEGO technology to learn what a robot is, how to build one, and how to program. General information about the Ohio 4-H program is on our robotics web page.

The files and videos on this page are for members and others taking the Robotics 1 with EV3 project.


It's been a great ride, EV3,
and we are sorry to see you go!

LEGO® Mindstorms® EV3 has been discontinued, with a limited number of kits still available. Our related curriculum and videos will remain available as long as they are needed by 4-H members and others.
