COMMON KINETICS

About Common Kinetics

Common Kinetics is a place to draw mechanisms and see them move. The builder solves your sketch with a real kinematics engine as you drag, runs it kinematically or with contact dynamics, and lets you save, post and remix. The library is a tagged index of thousands of animated mechanisms for inspiration.

What is in it

  • Build: links, sliders, gears, racks, belts, cams, springs, motors and custom profiles; parameters, probes, a timeline, posters and clips.
  • Explore: posts, votes, comments, remix lineage, profiles, challenges and a daily feature.
  • Library: mechanism videos by Nguyen Duc Thang (thang010146) with search and facets.
  • Classes: join codes, assignments from any template, submissions and grading.

API

Everything a signed-in person can do with designs and posts is available to scripts and assistants through a personal token (create one under Account & tokens). REST:POST /api/agent/<tool> with a JSON body; MCP: POST /mcp. Tools include design_create, design_run, design_sweep, design_export, post_create, post_vote, feed_list and feed_featured. Bring your own model: the API only moves data.
