Star Wars BB-8 Droid (V2)
Version 2 works much better! ...Now to just add a nice paint job. The Sphereo version uses wheels to roll within the shell, but I have chosen a different method of control. The robot has a pendulum hanging inside of the sphere which stays upright, and the sphere rotates around this. The pendulum can spin and swing left and right for turning.
I’ve included an explanation video of how the BB-8 Droid works, and a video covering my progress in the first 24 hours of the project. I’ve now moved onto version 2, which I hope will be more durable. I’m hoping to have that version done within a week or two.
