SCARA Robot

 

This video demonstartes how a 5-axis pick-and-place SCARA robot can be built with 2 of our hollow rotary actuators, a harmonic geared stepper motor, a compact cylinder and a compact gripper from the same product family.

To shorten the learning curve, all of these products use the same battery-free mechanical absolute encoder technology and use the same drivers.

1. A Custom-built SCARA Robot (Demo)
This custom-built SCARA robot (demo) was made using motors from Oriental Motor. Although Oriental Motor does not build or sell robots, we built this demo to show that our motors are suitable for articulated driving.
