Art Assistant

For this contest entry I have used nxt parts to make a mobile robot that assists with art such as painting and drawing. The ways it does this are by having an opening and closing claw hand to hold things like paintbrushes, pencils, rags, and more. Its other hand is meant to hold a paintbrush. after it grips said paintbrush, its motor spins, and if you have the paintbrush in water, it washes off the brush for you! To fit the theme of the contest, both hands can be activated by the nxt sound sensor.
