Hand Recorder GUI — Keyframe Gesture Animator

framework Flet (Flutter) streaming 25 Hz target Inspire RH56 format YAML presets

A desktop GUI for authoring and replaying precise hand gesture animations on the Inspire hands — dial in poses with six live sliders, record takes, and combine them into finished sequences.

Author, record, and replay 6-DOF dexterous hand poses at 25 Hz over RS-485 serial.
Interactive 6-slider GUI with live hardware feedback and automated kinematic smoothing.
Compose multi-take animations into unified YAML presets with dynamic playback speed scaling.
