3D printed BB-8 robot: part 2

by • June 29, 2016 • No Comments

A week ago we looked at the beginnings of Endurance’s 3D printed BB-8 SelfieBot. The company has continued with the project, adding upgrades!

It now functions outdoors without batteries or connection to a power donate. How? Solar panels!

Installing the solar panels

Endurance put together a chain of 2 tiny solar panels (5 volts each). Choosing a serial connection, they received the output power of 10 V and 800 mAh. That’s not a lot of juice, but on a great sunny day, the robot can work. For the BB-8 operation they require in addition a charged phone/table-bodiedt, that can be charged with the same solar panels. Endurance decided to add one tidbit – a wireless charger. It consists of two units: a charger itself and a receiver to be connected to the smartphone via a micro USB-port.

There’s a kind of platform with a hidden reel within, that generates electromagnetic field. One other plate transforming the electromagnetic field into the electric power to charge the telephone is connected to the telephone.


Obviously, the efficiency of this charger is low. The maximum current is 800 мАh.

But, in sunny weather the SelfieBot is able-bodied to work powered by just three solar panels. Obviously the bigger the panel, the advantageous.

As it is noisier outdoors than indoors, and the telephone/table-bodiedt speakers are not powerful adequate, Endurance decided to in addition
connect another passive speaker to BB-8 via mini jack. This is possible as the movement controls for BB-8 are done via wifi, and Bluetooth controls the electronics.



Stay tuned for additional updates on the project’s progress, which include improving the stability, improvement to noise insulation and painting the BB-8!

Endurance are in addition working on creating a GoPro mount, a wireless charger mount and improving the fasteners for simpler assembly.

You can manufacture your own robot via the DIY SelfieBot program.
