                        Rotary solenoids

                                A rotary solenoid is a derivative of the standard solenoid (see
                                Fig. 4.7). Instead of producing a linear motion, it produces a rotary
                                motion. A rotary solenoid can be used to create a robotic fish (see
                                Chap. 13).
