    Characteristics of Robots

                      There  are  some  essential  characteristics  that  a  robot  must  possess.  These
                      characteristics  define  whether  any  machine  is  a  robot  or  not.  Some  of  the

                      characteristics of robots are as follows:

                                                                 Characteristics
                                                                   of Robots

                                           Sense                  Movement                     Energy

                      Let us learn about these in detail.

                      Sense

                      Robots have some sensors that enable them to sense and create awareness about
                      their surroundings and act accordingly. Just like humans have sense organs, robots

                      may possess one or more sensors like:

                         • Light Sensors: work as eyes for robots
                         • Touch or Pressure Sensors: work as hands for robots

                         • Chemical Sensors: work as nose for robots

                         • Hearing and Sonar Sensors: work as ears for robots

                      Movement

                      A robot needs to be able to move around its environment. It may roll on wheels,
                      walk-on legs, etc. In the case of robots, the movement can be of the whole body or

                      just the arms. In humanoid robots, the entire body moves but for some industrial
                      robots, only their arms move and function.

                      Energy

                      To function or work, a robot needs power. It can work on solar power, electric

                      power, or can be battery operated. Which kind of energy will be best for the robot is
                      decided by the task it needs to perform. Heavy-duty robots that work in industries

                      may be electrically powered, whereas a robot on Mars may be solar-powered.
