Crapple is a walking robot which is able to draw fibonacci spirals with chalk. The robot interacts in the urban space, creating traces on the floor. The two motors, one for each side, are driven by an Arduino. Each side can be programmed individually so the robot is able to move in a spiral, with different walking speeds of each motor. The angle and pressure of the chalk is controlled by a servo.
