PARTS OF ROBOTS

                 As you all know, a robot is a programmable machine capable of performing tasks and

                 interacting with its surroundings. Robotics is the science and technology behind designing,
                 manufacturing, and applying robots. Robots cannot do anything by themselves. Different
                 parts of Robots are meant to perform different tasks.

                 First, let us understand the difference between humans and robots.
                 Essential Parts of Robots

                 Humans have set body parts, whereas robots have body parts according to their needs.

                 This is the reason robots come in different sizes and shapes. Industrial robots look very
                 different from Astronaut robots.
                 Let us study about some of the essential parts of Robots.
                 Manipulator


                 The robot’s Manipulator is just like
                                                             Wrist
                 a human arm and has several joints                              Hand
                 and  links.  They  are  electronically
                                                                         End Effector
                 controlled  devices  consisting  of        Elbow                               Wrist
                                                                                     Shoulder
                 multiple  sections.  A  manipulator
                 uses  strong  links  connected  by
                 joints with one fixed end and one
                 free  end  to  perform  a  given  job,        Shoulder                                        Elbow

                 such  as  moving  a  box  from  one               Robotic Arm                 Human Arm
                 location to another.
                 End Effector

                 End  effector  is  fixed  at  the  end  of  the

                 manipulator.  Manipulators  are  usually  set
                 and End effectors are free to end. They are
                 expected to perform the tasks traditionally
                 performed by human fingers and palm of a
                 human hand. The end effectors usually do
                 the work. They are attached to the robot’s
                 wrist and controlled through a computer.

                 Different types of End Effectors

                 There are mainly two categories of end effectors which are grippers and tools. Gripper,
                 at the end of a robotic arm, is the most commonly used end effector in various robots
                 like Mars rovers in the form of hammers and shovels. On the other hand, Medical robots
                 have specialised end effectors such as tools for cutting in surgery and suturing incisions.
