SG90 is a high torque motor that is commonly used in robotics and several other applications because it’s easy to control their rotation. SG90 Servo motor has a geared output shaft. SG90 also used as actuators in many robotic arms, or as a steering system in RC toys. Due to its lightweight, it can be used in multi-DOF robots SG90 Servo rotates approximately 180 degrees (90 in each direction) and works just like the standard kinds but smaller. It will fit in small places. It comes with 3 horns (arms) and hardware.ultrasonic sensor provides an easy method of distance measurement. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. A single I/O pin is used to trigger an ultrasonic burst (well above human hearing) and then "listen" for the echo return pulse. The sensor measures the time required for the echo return, and returns this value to the microcontroller as a variable-width pulse via the same I/O pin
