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.
