4. Sensor output
Output
Reference voltage
If Sensor output > Reference voltage, then Output=5V i.e. ‘1’
If Sensor output < Reference voltage, then Output=0V i.e. ‘0’

6.  An actuator is a mechanical device for moving or
controlling a mechanism or system.
 In short it is something that actuates motion.
E.g. Motors, Hydraulics, Pneumatics, IC engines etc.

10.  RPM: - Revolutions per Minute
In layman’s terms RPM is the speed with which
motor rotates.
 Torque: - Torque is the force which motor
can produce or in other words the load which
it can withstand.
Unit – Newton Meter

11.  More the
torque more
is the load
which it can
lift.

12. Torque α Current
RPM α Voltage

13.  Tell Requirements of motor in following
cases:
1. Robot has to climb a steep slope.

14.  DC Motors Motors
 Stepper Motors Brushless
motors

15.  H-bridge technique
