"Abstrator" is a painting machine which I developed and built in collaboration with the company Finetool in Lyss. The articulated arm of the painting machine is commonly used in industry as a stabilizer of the hand when grinding complex edges. Its various delicate joints allow it to reach every corner of the circular base plate. The paper is attached to it and rotated by an Edison Gramophone engine. The motor works without any power supply and can be raised by a crank movement by hand. There are different ways to paint with this machine. On the one hand, the articulated arm can be operated manually while the paper on the base plate is subjected to a rotational movement. On the other hand, the arm can also be connected by a rubber band with the base plate and thereby also fully automatically operate. The movements of the arm are random and can be controlled by hand only conditionally.
