A Few Reviews of Cubelets

By: Modular Robotics

In July, we shipped out our first production run of 100 “beta test” KT01 20-Cubelet kits.  That might not sound like a lot of robots, but 100 kits means 2000 Cubelets.  Each Cubelet has 6 circuit boards and 24 tiny magnets in it, so the quantities were actually pretty large.

Our first 100 customers were extremely patient.  Some of them pre-ordered Cubelets back in October 2010 and waited patiently while we dealt with some manufacturing, material, and supplier challenges.  But Cubelets are finally out in the world.

We’re busy manufacturing our second run (5000 Cubelets this time), but our early-adopter friends have already started posting reviews and videos of their first experiments and play sessions.  They’re definitely worth looking at.
