Description<\/strong><\/p>\n

This project is a double transducer that takes a rotational position (0-90) as input and produces a frequency of tapping (20-60 taps per min) as output. The double transducer takes in the rotational degree and adjusts the rotation of the stepper motor accordingly. The stepper motor then drives the pulley to change the position of the obstacle. The ultrasonic ranger detects the distance between the obstacle and itself to adjust the frequency of tapping in accordance.<\/p>\n

Overall Logic:<\/p>\n

Rotational Position (Potentiometer) –> Stepper Motor Rotation –> Pulley System Movement –> Obstacle Movement –> Distance Detection by Ultrasonic Ranger –> Frequency of Tapping (Solenoid)<\/p>\n
