Locomotion Device
                  Human  beings  use  muscles  to  give  movements  to  their  arms,
                  palms  and  fingers.  For  a  robot,  the  power  comes  from  motors.
                  Three  fuels  are  used  in  locomotion,  depending  on  the  energy
                  source. There are three widespread types of Locomotive devices
                  namely Electric, Hydraulic and Pneumatic.

                                                    Controller

                                                    Human beings and animals sense their surroundings through
                                                    their  sense  organs  and  then  react  accordingly  based  on  the
                                                    sense organs’ feedback. Robots use the same response system
                                                    as human beings-the feedback system. The CPU of a robot does
                                                    the same thing based on data collected by its sensors. There are
                  mainly two types of controllers that determine the robot’s behaviour. They are Simple Controller
                  and Strong Sensory Controller.

                  Sensors

                  Without the data supplied by the sense organs, the
                  human  brain  cannot  perform  intelligently  in  any
                  given situation. Similarly, controllers would be unable
                  to  perform  if  the  robot’s  sensors  do  not  constantly
                  feed  the  controller  about  their  position,  force,
                  temperature, etc. The sensors are the powerhouse of
                  a robot’s feedback system and act as eyes and ears.
                  A wide range of sensors is used in a robot system to perform the tasks.

                  Power Supply

                  Just  like  human  beings  consume  food  when  they  need  energy,  robots  need  energy  too  to
                  function. Electricity is the primary source of energy for most robots. Stationary robots used in
                  the factories use direct power. Mobile robots use high-capacity batteries. Robotic spacecrafts
                  and satellites are generally equipped with solar panels.
