Backport of the keyboard device from main, hand-ported rather than cherry-picked: this branch predates both the manifest-driven tracker codegen (trackers.toml doesn't exist here) and the consolidation of isaacteleop's Python source under src/python. KeyboardTracker is therefore hand-written (deviceio_base interface, deviceio_trackers facade, live_trackers/replay_trackers impls + factory dispatch entries), following generic_3axis_pedal_tracker's structure exactly, and the Python-side files live at this branch's pre-consolidation paths (src/core/retargeting_engine/python/..., src/retargeters/...). Feature set matches main: - keyboard.fbs + KeyboardTracker: raw per-key press state (pressed_keys: [ushort] of evdev key codes), no semantic mapping. - keyboard plugin: standalone Linux evdev reader, self-discovers its device under /dev/input/by-path/, auto-launched by PluginManager. - KeyboardSource (IDeviceIOSource) exposing "keyboard" (fixed 13-key SE3 subset) and "keyboard_all_keys" (256-entry bitmap, every key). - KeyboardToSe3RelRetargeter and KeyboardGripperRetargeter. - keyboard_printer_example.py.

📝 WalkthroughWalkthroughThis change adds Linux evdev keyboard support across the stack. It defines keyboard FlatBuffers data and Python bindings, adds live and replay tracker implementations, builds and packages a keyboard plugin, and exposes Python source nodes and retargeters. It also adds a keyboard printer example and end-to-end tests. Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The keyboard recovery path can continue publishing stale key state when resynchronization fails, so a released key may keep driving teleoperation; the example also does not start the required keyboard plugin. These concrete control and integration issues make the PR unsafe to merge until corrected. Sequence Diagram(s)sequenceDiagram

- Line 26: Update PLUGIN_ROOT_DIR in the keyboard printer example to use the
bundled plugin search path, resolving the source-tree location
src/plugins/keyboard and the installed-wheel location
isaacteleop/plugins/keyboard as appropriate. Ensure the existing plugin
existence check and launch flow can find the keyboard plugin and receive
keyboard data.
In `@src/plugins/keyboard/keyboard_plugin.cpp`:
- Around line 99-106: Update open_device() to query EVIOCGKEY after a successful
open and initialize pressed_keys_ from the returned key bitmap. In update(),
handle EV_SYN/SYN_DROPPED by discarding events until the next SYN_REPORT, then
rebuild pressed_keys_ via EVIOCGKEY before resuming normal EV_KEY processing;
preserve existing press, release, and autorepeat handling.

KeyboardToSe3RelRetargeter and KeyboardGripperRetargeter read a separate fixed 13-key TensorGroupType (KeyboardInput), while KeyboardToSe2Retargeter already read the 256-entry keyboard_all_keys bitmap. Move SE3 and the gripper onto keyboard_all_keys too, so KeyboardSource has a single output and every retargeter shares one bitmap-indexing convention. Introduce EvdevKeyCode, a comprehensive IntEnum of standard evdev key codes (linux/input-event-codes.h), replacing both the removed KeyboardInputIndex and keyboard_se2_retargeter.py's raw magic-number key constants. Removes KeyboardInput/KeyboardInputIndex entirely (pre-release, never shipped) rather than deprecating. Signed-off-by: Rafael Wiltz <rwiltz@nvidia.com>
