Abstract
A robot that can make a hollow doughnut with ultra-thin shell is proposed in this work. The thickness of the doughnut is limited by the viscosity of uncooked dough, and even an experienced cook cannot make a hollow doughnut beyond such a thickness limitation, hi order to make an ultra-thin doughnut for a new texture, a high-speed spinning cook robot is developed. The robot includes two parts, a free-spin mold mounted on an electric motor and an external heater. By high-speed spinning, a great centrifugal force is evenly applied to the uncooked dough inside the mold while the mold is cooked by the heater. The thickness of the produced hollow doughnut is successfully achieved 150 micron which is far beyond what a human cook can do. The design of the robot and the texture of the ultra-thin shell are discussed.
