exploring the relationship between machine and art, so kanno and takahiro yamaguchi
have created 'senseless drawing bot', a self-propelling device on a skateboard that sprays
abstract linework on a stretch of wall using a double pendulum. extrapolating the dynamism
of modern graffiti forms, the robot takes advantage of the chaotic gestures of the swinging
pendulum to create erratic yet organic paint strokes.
featuring a motorized skateboard base, the construction consists of a single arm equipped
with a rotary encoder attached to the fulcrum of the pendulum. as the robot moves from
side to side, the swinging motion of the arm is amplified through the physics of inertia
which is delineated by a quick release of paint from the spray can. the resulting collage of lines
is a complex illustration derived from a simple operation.
