With a few servos and bit of imagination you can have a lot of fun with the results, and with some extra work Laura Greig Lippincott has created her painting robot going by the name of Neko. By mounting the four servos on an arm created from Makerbeam, a credible replica of the human arm can be controlled by an Arduino. With this a painbrush is attached and the device can be set to move the paintbrush over a canvas. With the addition of an ultrasonic distance sensor to the "hand", Neko can then determine the distance between the brush tip and the canvas which can be used to increase the level of creativity of painting.
