Joints in R3 with your AI: hinges, sliders and welds

1:09 · 2026-11-05

One request to Claude, connected to R3: show how joints work. Claude reads R3's joints how-to, builds five fixed hooks with a pendulum, a hinge that stops at 45 degrees, an arm a motor turns, a block on a slanted rail and a welded block, checks them running in the editor and gives a preview link. Narration: AI voice.

0:02 With R3 connected, ask Claude to show you how joints work. A pendulum, a hinge, a motor, a slider, and a weld.

0:14 Claude reads R3's joints how-to, and makes a new project, with a floor, and a fixed hook for each joint.

0:25 It makes each hook a fixed body, and adds the parts that move. A weight, an arm, and two blocks.

0:35 Then the joints. Three hinges, free, limited to 45 degrees, and turned by a motor. A slider on a slanted rail. And a weld.

0:48 It runs physics in your editor, and reads where each part is, to check that it moves as it should.

0:55 It writes a help page, and gives you a link to try it.

1:00 Open the link, and press Start. Each joint moves its own way.
