  1. FOLLOWER SENSORS AND ACTUATORS EE 552 INTSTRUCTOR :Dr MOHAN KRISNAN BY MOHAMMED KASHIF IQBAL ANESH BODDAPATTI UNIVERSITY OF DETROIT MERCY

  2. Flow chart

  3. Follower • A Small mechatronic system • Detects the object • Measures the distance from object • Generally moves forward • If obstacle is detected then moves backward

  4. Video of follower

  5. SENSOR A device that responds to a stimulus like heat, light, pressure etc and generates a signal is called as sensor A sensor converts physical parameters to electrical parameters

  6. IR PROXIMITY SENSOR

  7. IR proximity sensor • Works by sending out a beam of infrared light • computes the distance depending on the reflected light • Voltage varies depending on reflected light

  8. IR proximity sensor • Triangulation method

  9. SENSOR SPECIFICATIONS IR Proximity Sensor ( GP2D12) product from SHARP Distance output type : Analog Detecting distance : 10 to 80 Cm Operating Supply Voltage : 4.5 V to 5.5 V Output Voltage Range : 1.75 V to 2.25 V

  10. ACTUATOR A device which activates Performs mechanical motion with the values of signal given by sensor

  11. Stepper motor

  12. Stepper motor An electromagnetic actuator it is digital actuator Moves in fixed angular steps

  13. DATA ACQUISITION • System which acquires data by digitizing analog channels and storing the data in digital form. • capable of automatically collecting data from sensors • can be used alone or with a computer • acquire multiple channels of data.

  14. USB 6009 product of NI

  15. USB 6009 product of NI • used as a interface between computer and hardware • small, portable multifunction data acquisition device • 12 Bit digital I/O lines • 2 true DAC analog outputs for accurate output signal • here we used to measure sensor signal and generate pulses to control DC stepper motor

  16. Computer • used to run software of NI Lab-view 7.0 • to save data • It is connected to USB 6008 DAQ Card

  17. Software (LAB-View 7.0)product of NI • Lab view is a platform for a visual programming • Has many libraries and tools. • The graphical language is named "G". • Used to design, control and test

  18. Flow diagram SENSE RESPOND INTERPRET

  19. Future development • Able to move in all directions • Able to detect obstacles in long ranges • Can be installed in automobiles • Can be used to control speed of vehicle

  20. drawbacks • Presently moves only forward and backward • Sensor can detect only in a small range

  21. References • www.hitechnic.com • www.ni.com/daq. • www.google.com • www.globalspec.com

  22. conclusion • Project is successfully completed as shown in the flowchart

  23. Q & A Session
