Stacking cups with a robot arm

One of the things that automation firm Sisu Devices LLC does is devise clever trade show exhibits. This one involves two Scara arms guided by hand motions captured by a Leap Motion Controller, normally used to incorporate hand motions as part of a computer user interface. The user interface responds to these points and swipes like a touch screen. Pinchers at the ends of the robot arms are also activated by gestures. The idea was to direct the robot arms to stack a few cups before time ran out. The NIWeek demo was based on a display originally created for a Boy Scouts of America outpost where the arms would tie different knots that Scouts normally learn.
