The web GUI for OpenServoCore servos. It talks to an osc-adapter over WebUSB through @openservocore/client, the wasm build of the host library that lives in the monorepo at client/web. Connect the adapter, discover the servos on the bus, and read or write their control tables from the browser.
WebUSB only exists in Chromium-based browsers, so this runs in Chrome (and Edge, Brave, Arc); Firefox and Safari cannot open the adapter. To run it you need Node 26, the Rust nightly toolchain with the wasm32-unknown-unknown target, and wasm-pack. Clone the monorepo next to this repo as ../open-servo-core, then npm run wasm to build the bindings, npm ci, and npm run dev. The bindings are a local-path dependency (file:../open-servo-core/client/web) until the package is published, which is why the sibling checkout is required and why npm run wasm has to run before npm ci.
Open the dev server with ?sim=1,2,3 (any comma-separated list of servo ids; bare ?sim gives ids 1 and 2) to drive a simulated fleet instead of an adapter. The servos run inside the wasm module, so every page works the same way it does on the bus.
npm test runs the unit tests, npm run test:e2e runs the browser tests headless against the dev server, and npm run test:e2e:ui opens the Playwright UI to watch them.
