Gantry Pick and Place

A cartesian gantry robot moves only along its three axes: the bridge rolls in x, the carriage in y, the z-axis drops, grips the accent part and sets it on a fixture across the table.

Also known as: pick and place animation, robot arm animation, isometric factory, hairline animation.

Customizing this snippet

  • Color: set --hln-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --hln-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
  • Speed: change the duration on the transition or animation shorthand. Staggered delays are relative, so they keep their rhythm.
  • Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
