On seeing that there was no working LEGO BB-8 Droid on the shelves at Christmas 2015, and only ready-made products from other companies that would not hold my interest, I decided to do what I could to redress the balance. Here is my project to create a moving Technic BB-8 droid with Power Functions. The aim of the project is to make a driveable BB-8 droid with Power Functions that the user would build from instructions like a normal Technic kit. I will leave programmability as an option for EV3 experts to do in another project. SInce one of the criteria for viability as a LEGO set is the price point, I am aiming for £100, similar to the Cargo Plane 42025. Even with the motors I hope it will end up no more expensive than the Crawler 4x4. The Sphero product is £130 so my project needs to demonstrate equal value to the user for that sort of price. So far I have a Technic sphere with an internal mechanism to roll it, though I am making improvements before making a video. I started with a tiny head for the first prototype, then a rather squashed head for the second one. Now, with the first update to the project I have a much better head shape. The head also has a self-levelling mechanism. The sphere, made with Technic axle joints and panel pieces, is a bit uneven, so I have improved that too. The updated head is designed to cope with some unevenness. I hope to get it to roll reliably soon, so that I can post a video for a further update. There will be more updates throughout the year as I make improvements. Please would you take a look and support the project. Remember that you will be supporting the idea of a driveable LEGO Technic BB-8 droid that the user can build themselves; I will get as far as I can this year, or in any time extension that is granted following your support. Many thanks! Please spread the word and share with your friends. It will take a lot of support for us to let the LEGO company know we want them to produce a moving BB-8 droid in a set! Mark
