With light sabres,
Yaskawa equipped robots. Hmmmmmm.
For this year's IEEE International Conference on Robotics, the robotic company equipped two robotic arms with Jedi and Sith light sabres and taught them to fight. OK, maybe not to fight but it makes a nice fight choreography as shown in the video below.

This is much better than the first time Yaskawa gave Light sabers to their robots and simply made them dance (without fighting at all). The dance is shown below.
