Variations Too is a set of four motorized robotic arms which perform a variety of motions articulated in a single plane. The arms move in response to the presence and distance of viewers. It is a preliminary study for a larger installation of five arms that teach themselves a dance (as opposed to many art-robots that fight among themselves). An initial video of the piece, showing a range of motions is here: https://youtu.be/eAmCF4pdUsQ
Note that this is a 'first-run' sort of video and the actual motion sequences need to be developed.
