Karakuri Automation

How Does Karakuri Work?

Working Smarter

SUS's Karakuri Mechanisms utilize gravity and the natural weight of items to achieve simple automation. Many tasks that once required an operator can now be unmanned. And because traditional karakuri mechanisms don't require electricity, operational costs are minimized for truly lean manufacturing.

Link Mechanism

The Link Mechanism consists of joints specially designed to be long lasting. Its ability to convert between circular motion and linear force makes it useful for a wide range of applications.

Movable Pulley

The Pulley System demonstrates the relationship between force and distance. By understanding the basic principles of pulleys, you can move items long distances or change the effort needed to move a load.

The corner table rotates 90 degrees and then returns to its original position via counterweight. The orientation of the tote is maintained.

The corner table tilts and then returns to its original position via counterweight. The orientation of the totes changes.


The intermittent stopper rotates, allowing the tote to move forward. Any subsequent totes would be held in place by the rear arm of the stopper.

Depressing the foot pedal activates the see-saw and releases the front tote while simultaneously holding back any subsequent totes.
