Kinematic Hand Skeleton Optimization in Jax

I've been trying to wrap my head around fwd/bwd kinematics for imitation learning, so I built a fully‑differentiable kinematic hand skeleton in JAX and visualized it with reruns new callback system in a Jupyter Notebook. This shows each joint angle and how it impacts the kinematic skeleton.

In plain words

Kinematic Hand Skeleton Optimization in JAX is a fully-differentiable hand skeleton model built in JAX for studying forward and backward kinematics in imitation learning. It visualizes joint angles and their effects on skeletal movement through an interactive Jupyter Notebook using Rerun's callback system. The tool is designed for researchers and developers working with robotic hand control and kinematic learning problems.

  • Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
