A Small mechatronic system
► Detects the object
► Measures the distance from object
► Generally moves forward
► If obstacle is detected then moves backward

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

IR PROXIMITY SENSOR
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

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.

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
drawbacks
► Presently
moves only forward and backward
► Sensor can detect only in a small range
