The Senster was a robotic sculpture developed by Edward Ihnatowicz in the late 60′s. It was commisioned by Philips and part of their permanent showplace, the Evoluon, in Eindhoven between 1970 and 1974. It was the first robotic sculpture to be controlled by a computer and could react to the behaviour of the visitors with its sound and movement sensors. The computer used to control The Senster was a Philips P9201 and had only 8K of core memory. Now, almost 40 years later, every interaction student could make something like this and fit the logic in a small box. But this is still an amazing project.
This was the control panel of the Senster.
