README
README.mdVision Arm
A robotic arm that mimics the movements of a human's arm using computer vision.
Getting Started
The project has several components that need to be running:
Computer Vision
- Clone the repository
- Install
uvby following their documentation - Run
uv run python main.py <args>
<args> should be any of the following:
calibrate: Calibrate the cameras with the charuco boardtrack: Start tracking with multiple camerasmono: Start with a single camera (mostly for debugging)
STM32
The following STM32 toolchain setup is for Linux systems. A Linux system is recommended, but MacOS or Windows systems should work with some tinkering. (WSL is useful for Windows systems.)
- Install the following packages (for a Debian-based system):
gcc-arm-none-eabibinutils-arm-none-eabicmakemakeopenocd
- Navigate to the
stm32directory - Create the build directory with
cmake -B build -S . - Compile the microcontroller code with
cmake --build build(this can be skipped if you also want to flash the STM32) - Flash the microcontroller with
cmake --build build --target flash.

Questions
How big is the Vision arm PCB?
It measures 110 × 124 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vision arm use?
68 parts, built around the ACS711ELCTR-12AB-T, TXS0102DCUR, IRF9Z34NPBF and AMT0440007DB0000G. 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 Vision arm KiCad files?
From the deanasmith/vision-arm repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb and its schematic pcb/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vision arm design in my own project?
Its repository states no licence, so its author keeps all rights: ask deanasmith before reusing the design.
