How BB-8 Works Revealed At Star Wars Celebration Europe

Posted on by

Finally the workings of the official BB-8 that you’ve seen rolling around at various events have been revealed. Its makers [Matt Denton] and [Josh Lee] participated in an hour-long presentation at Star Wars Celebration Europe 2016 just this past week where the various views of its internals were shown in action. It’s since had BB-8 builders (yours truly included) analyzing the workings for new ideas. We also now have the official name for it, red carpet BB-8.

For the first half of their talk they went over how BB-8 was implemented for Star Wars: The Force Awakens. As we’ve long …read more

LEGO Monowheel Corners Like It’s On Rails

[Jason]’s at it again. This time the LEGO maestro is working on a LEGO BB-8 droid. As a first step he’s made a motorized monowheel that not only races along hallways and through living rooms at the peril of any passing people, but turns as well.

To drive it forward there’s an axle that runs across the center of the wheel and a motor that rotates that axle. He’s also included some weight bricks. Without the mass of those bricks for the rotation to work against, the motor and axle would just spin in place while the friction of the …read more

Driving BB-8: More Than One Way to Move this Bot

Posted on by

BB-8 is the much loved new droid introduced in the 2016 movie Star Wars: The Force Awakens, though in my case from the very first trailer released in 2014 I liked it for the interesting engineering problems it posed. How would you make a robot that’s a ball that rolls along, but with a head that stays on top while the ball rolls under it?

To make the ball roll, the answer most people found obvious at first was to use the analogy of a hamster wheel. The hamster running inside makes the wheel turn. In the BB-8 building world, …read more

Perfecting The DIY BB-8

Posted on by

Until about a year ago, the Droid Builder’s Club had just about everything figured out to build any sort of robot from Star Wars. Building an R2D2 clone was easy, and even R5 and R6 droids were common. There were even a few attempts to clone IG-88. Then Disney happened, The Force Awakens was released, and the world was introduced to the hero of the third trilogy, BB-8. Several people have gone to incredible lengths to replicate BB-8 as a unique homebrew robot, but no one has put in more effort than [James Bruton]. He’s wrapping up his third DIY …read more
