Promoting mechatronic art & sustainable energy in South Africa one g☼ggab☼t at a time
What is this project about?
It is about spreading access to and an interest in electronics and art.
It also raises awareness about sustainable energy and the current development in South Africa of legislation regarding small scale solar energy generators. The project is driven by Miranda Moss and Oliver Walkhoff and is made possible with the support of the Swiss Arts Council Pro Helvetia. Find out more on the project website:
What is a g☼ggab☼t?
A g☼ggab☼t is a small solar-powered robot. About 200 of them have been built in workshops during ISEA 2018, Durban, and subsequently at Baleni Senior Secondary School, Kwazulu Natal, South Africa.
A g☼ggab☼t consists of a printed circuit board (pcb), one or two solar cells, a motor, a capacitor and some mechanical parts. For the workshops, the pcb was pre-populated with smd components. The participants soldered the larger components to the board and added bristles, wire, beads and other things to create their individual bot.
How can I build my own g☼ggab☼t?
We have created a pamphlet with a short description of the parts and some building instructions:
How does the circuit work?
A schematic and a short description of the g☼ggab☼t circuit is also on the pamphlet. It was contributed by Uwe Schüler of Kulturgüter-Schuppen, Dusslingen, Germany.
How was the pcb made?
The pcb was created using KiCad Version 4.0.7. The boards were manufactured by PCBWay in China, and assembled by R2 Manufacturing, Glattbrugg, Switzerland.
The KiCad and Gerber files which were used for production can be found in this repository.

Questions
How big is the Goggabot PCB?
It measures 55 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Goggabot use?
21 parts, built around the BC817 and BC807. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Goggabot KiCad files?
From the owalkhoff/Free_Sunshine repository on GitHub, at the commit this page was made from: the board is goggabot/kicad-4/goggabot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Goggabot design in my own project?
Its repository states no licence, so its author keeps all rights: ask owalkhoff before reusing the design.
