MOSS Robot Construction Kits


We’re sad to say that we have ceased manufacturing all of our MOSS products. There are still some MOSS blocks available for purchase on our website here, but supplies are limited. MOSS products are covered by the Modular Robotics one-year warranty.

If you don’t see a certain MOSS unit for sale on our website, it is possible that we still have that item in stock. Please contact us at to ask! We no longer have the Exofabulatronixx 5200 Set or the Double Brain unit available for purchase.

8-10 year olds will benefit greatly from learning the basics of MOSS construction alongside an adult or group. While Cubelets are fairly intuitive for all ages, the MOSS system can be challenging for younger students to get started with.

Each MOSS robot construction kit comes with a booklet specific to the set. Begin by reading the Getting Started section and identifying the different components of your MOSS kit, then pick one of the sample robots found in the booklet and start building!

Check out our MOSS Robot Recipes for some ideas on your next robotic construction! These recipes detail step-by-step robot building instructions in 3D space.
