Floribots
Floribots, a massive art piece created by Geoffrey Drake-Brockman in 2005, is essentially an array of 128 simple folding paper flowers that are mechanically controlled. Each large flower extends out of a rigid base, and is capable of mechanically "blooming" and extending higher. Operating under a collective "hive-mind," they are capable of reacting to movement stimulus and even has an array of different "moods" they can display through dynamic movement.
Outerspace
Outerspace is a reactive robotic creature with lifelike interactive behaviour. The robot wants to explore the world surrounding him, or the outer space, exhibiting curiosity and waryness as an aprehensive animal might. A participant may put a hand up to the robot and cause it to pull away, as if surprised at the recognition of another being, then move forward searching for the thing that caught it’s attention. The concept that insprired the work was that an object, inherently not living, cannot have emotion. In order to create an emotional object (the goal), first the thing must be aroused, feel, have a emotion; then comes emotional expression. In technical terms, it must read input and display output.
