This is the guy I would like to build since my first R2D2 is almost finished.
BB8 appeared in SW EP7 and is the work of Matt Denton and Josh Lee.
Matt Denton & Josh Lee
This is BB8 MK1 (or Red Carpet version) made for "The force awakens" premiere.
Not used in that movie.
Above and right:
This is (propably) MK2. Made for "The last Jedi" and was used in that movie and also "Rise of Skywalker".
Above:
Matt and Josh in a 7 second clip from "Galctic Builders" showing the MK2.
The 7 seconds from the TV-show only shows part of the mechanics and only from one side. So my work this far is VERY much guessing.
This is not accurate as far as I know now. It should propably be ordinary caster wheels instead of the Pololu ball casters I used above.
