INTRODUCTION TO THE REV DUO SYSTEM: Competition Proven, Classroom Ready

The REV DUO line of parts work together for a dual purpose: To create competition-grade robots geared towards participating in the FIRST Tech Challenge or to be used in the classroom for STEM education.

REV Robotics is committed to designing high-quality products that make robotics accessible for any skill level. Since 2014, we have continued to iterate and adapt to the educational robotics community's needs, by developing new products and refining our current product selection.

REV DUO is a new brand that now includes all of our existing products and is the home for many new products coming soon. Look for the REV DUO brand on our website and shop with confidence knowing all products are compatible and designed to work together seamlessly.
