    Legged (Walking) Robots

                                                                Description
                                                                Robots that use legs (two, four, six, or more) to walk. They mimic
                                                                animal locomotion.
                                                                Advantages
                                                                Can navigate very challenging and uneven terrain, climb stairs,
                                                                step over obstacles, and operate in environments where wheels
                                                                would fail.
                  Disadvantages
                  Mechanically complex, higher power consumption (especially for dynamic balancing), slower speeds, more complex
                  control algorithms for stable walking.

                  Example
                  Humanoid robots (two legs), quadruped robots (four legs, like “Spot” from Boston Dynamics), hexapod robots
                  (six legs).

                                        The Runaway Robot
                                        It was a chilly afternoon in Japan when a children’s robot, left unsupervised in a shopping
                                        mall, was ambushed by a gang of kids. Instead of fighting back, the robot employed a clever
                                        trick—it scanned for tall adults, darted toward them for safety, and escaped being pelted
                                        with candy and kicked by tiny sneakers. Engineers later programmed an “abuse-evasion”
                                        system based on this wild day.
                   actual funny
                      incidents         Learning: Robots sometimes need to be protected from humans, not the other way around.

                  Tracked Robots (Crawler-Type)
                  Description

                  Use continuous tracks (like a military tank) for movement.

                  Advantages
                  Excellent traction on loose or uneven surfaces (sand, gravel, mud), good for climbing
                  over small obstacles, highly stable.
                  Disadvantages
                  Slower speed, less energy efficient on hard surfaces due to high friction, can damage
                  delicate surfaces.

                  Example
                  Exploration robots for rough terrains, military robots, some search and rescue robots.

                                                            Aerial Robots (Drones)

                                                            Description
                                                            Robots designed for flight, typically using propellers (multi-rotors
                                                            like quadcopters) or fixed wings (will be discussed much in detail in
                                                            next topic).
