Illustration for article titled Industrious Robot Scans Onion, Sculpts Onion

There's a saying that a watched pot never boils. You could also say that a watched plant never grows—unless it's being watched by a laser-wielding, 3D plastic sculpture-printing, growth-tracking megarobot.


David Bowen's "Growth Modeling Device" uses a circular rig to scan an onion once a day with a laser, then employing a "fuse deposition modeler" to generate a plastic sculpture of that scan. When the model is done, a conveyor belt burps into action, moving the recreated onion out of the way and making room for the next day's piece.

What you end up with is a visual record of the onion's growth over the course of a few weeks—with no tears involved!


David Bowen has all sorts of other neat kinetic sculpture works up on his site. [David Bowen via Boing Boing]
