3d Print Files
Look in 3d_print folder to find a 3mf file with the chassis , camera holder and wheels ready to print.
Software
Setting up video streaming and remote control is very easy.
Clone this repo to a raspberry pi, navigate to web_server/keyandvid/
From there run "python app.py" and the web server will start
Then you can navigate to your pis ip address using a computer on the same wifi. Use port 8000.
For example : 192.168.0.186:8000 and you should see your video stream. The robot can be steered using the WASD keys on your keyboard
PCB Files
The hat was designed in Kicad 7. All project files are in kicad_files.
The board was made and assembled by PCBway. If you wish to get your own board assembled using PCBway look in kicad_files/pcbway_production for all of the required PCB manufacture and assembly files, ready for upload to JLCPCB.
Youtube video
I made a short video explaining the project. It is available here:

Questions
How big is the Povbot2 PCB?
It measures 65 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Povbot2 use?
29 parts, built around the TB6612FNG,C,8,EL, TPS61232DRC, MCP73831-2ACI/MC and B2B-PH-K-S. 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 Povbot2 KiCad files?
From the wattnotions/povbot2 repository on GitHub, at the commit this page was made from: the board is kicad_files/povbot2.kicad_pcb and its schematic kicad_files/full_sch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Povbot2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask wattnotions before reusing the design.
