6B Robo - sound performances and the human-machine relationship

Skeletal Reflection’ is also, like Stelarc’s ‘Anatomical Exoskeleton’, a pneumaticly driven robot. Mark Ruch, managing director and tour manager from Amorphic Robot Works, expresses the choice of amplifying the beauty of the machine:

As there is a beauty and elegance in movement itself, there is equally potent an experience in watching a machine (human or organic in form), struggling to stand, attempting to throw a rock, or playing a drum. These primal activities, when executed by machines, evoke a deep and sometimes emotional reaction. It is the universality of emotional experience which intrigues us, and it is the contrapunctal use of machinery as artistic medium and organic movement as form which, perhaps ironically, combine to provoke these emotional reactions most readily (Ruch 2000).

But the robot doesn’t necessarily have to entail a more or less natural process to exhibit a ‘Primal Scream’ imitation of movement and sound. A machine could become more abstract as soon as art elements like sound, movement, visuals or light are more implicitly involved. The addition of the above mentioned art elements can make it possible to transform the machine into an extremely surreal artpiece as we can read about below:

The word ‘robotics’ can mean many things - and so can ‘art’. To some, robotics is about factory-automation systems - giant robotic welding arms and such. To others, including most ‘hobbyists’, a robot is autonomous and mobile, with wheels or legs, eyes or obstacle detectors, a gripper, and an on-board control and navigation system. Artists can use it in a much more general sense, which escapes easy definition (as does art). It can include everything from simple motorized sculptures to complex computer-controlled environments (Mann 2002).

However the following robotics project by Host productions ‘Small Work for Robot and Insects‘ underlines the idea that pure naturalistic sounds can also enhance the machine - sound relationship. This project is also inspired on crickets (like ‘Anatomical Exoskeleton’). Here the hexapod robot dances to an electro-environmental soundtrack performed live by a group of singing crickets in a big glass box. The piece consists of a group of crickets and a quadroped robot existing in a large glass tank, separated by a glass divider. The sound of the cricket song is sent to the robot which responds by making a series of movements. Simultaneously the computer “intercepts elements of the crickets' song and robot's motor noise merging, pitch shifting, delaying and looping to produce a generative soundtrack to the actions in the tank.” The robot was then developed to listen ‘intelligently’ to the cricket song and to try to devise a language through which to communicate. The crickets’s sound is monitored and  analysed by fft processes in MAX/MSP. These data are passed to a neural network and then processed on a macOSX computer. The derived numerical representation of the ‘sentence’ is returned to MAX/MSP  which relays it to the robot which is programmed to construct these ‘sentences’ in which a ‘word’ can be a sound, a motion or a light sequence.  The robot is equipped with an onboard microprocessor which controls its functions which are directed by the data coming from the neural network (Andy Gracie  2003). ‘Small Work for Robot and Insects’ tries to create a novel behaviour by comparing the specifics of systems that interact with a natural element (the crickets) using the neural network programming concept.
