    High cost: Building and maintaining robots can be expensive, especially for complex tasks or
                         advanced or industrial-grade models.

                         Vulnerability to malfunctions: Robots can break down due to mechanical failures, software
                         bugs or sensor malfunctions, which can disrupt their ability to perform tasks.
                         Job displacement: Robots can replace human workers in various industries, which may lead

                         to job loss and create economic challenges.
                         Ethical  concerns: The increasing  complexity of robots  raises  questions  about  their  role in

                         society, privacy issues and the ethics of robots making decisions that impact human lives.

                      GENERATIONS OF ROBOTS

                      Robots  have  evolved  through several generations,  each  marked  by  key  technological
                      advancements.  Below are the different generations  along with the approximate  years  when
                      they emerged:

                      1.  First  Generation - Mechanical  Robots (1950s - 1960s):
                         These robots were simple mechanical devices designed to
                         perform repetitive tasks, often in manufacturing. They were
                         manually  operated  and controlled  and  had  very limited
                         flexibility.  The most  notable  example  is  the  Unimate, the
                         first industrial robot, which introduced at General Motors in
                         1961 to handle die-casting and welding operations.

                                                         2.  Second Generation - Programmable Robots (1970s - 1980s):
                                                            Robots of this generation could be programmed to perform
                                                            specific  tasks,  offering more  flexibility  than  the  first
                                                            generation.  They  were used  in  industries  like  automotive
                                                            manufacturing  for more complex  tasks,  like  welding  and
                                                            painting. However, these robots still required human input
                                                            for programming and operation.

                      3.  Third Generation - Autonomous Robots (1990s - 2000s): Robots began

                         to operate with greater autonomy, using sensors and basic AI to make
                         decisions based on their environment. These robots could perform tasks
                         like inspection, material handling and packaging without human control.
                         The ASIMO robot, introduced by Honda in 2000, was one example of a
                         robot with basic autonomous capabilities such as walking, climbing stairs
                         and interacting with humans through voice and gesture recognition.
