    Mechanical Engineering Principles Behind Cranes

                     A crane is a powerful machine used to lift and move heavy objects from one place
                     to another. Cranes are usually seen at construction sites, where they help lift
                     materials like steel beams and concrete blocks.

                     Key Mechanical Principles

                                                          Leverage: They work on the principle of leverage to lift heavy
                                                          objects. The longer the boom, the less force is needed to lift a
                                                          load. This is because the load is farther from the pivot point
                                                          (the base of the crane).

                      Balance: Just like a seesaw, cranes must maintain balance. The
                       counterweight is essential because it offsets the weight of the load
                       being lifted. If the load is too heavy without enough counterweight,
                       the crane can tip over.

                                                  Mechanical  Advantage:  This  principle  allows  cranes  to  lift  heavier
                                                  loads with less efforts. The combination of pulleys and the length of the
                                                  boom helps distribute the weight, making it easier to lift heavy items.

                     Overview

                     Robo Crane is a different project designed to educate us about robots, machinery,
                     and  electronic  components.  It  resembles  a  specialized  crane  equipped  with
                     robotic  capabilities,  enabling  it  to  lift  and  transport  objects.  Building  and
                     observing its functionality provides valuable insights into its operations.

                     Learning Objective

                      Build a Robo Crane capable of lifting and relocating objects.

                      Acquire knowledge about fundamental robotics, mechanics, and electronics through hands-on
                       projects.
