A humanoid robot is a robot with its body shape built to resemble that of the human body. A humanoid design might be for functional purposes, such as interacting with human tools and environments, for experimental purposes, such as the study of bipedal locomotion, or for other purposes. In general, humanoid robots have a torso, a head, two arms, and two legs, though some forms of humanoid robots may model only part of the body, for example, from the waist up. Some humanoid robots may also have heads designed to replicate human facial features such as eyes and mouths. Androids are humanoid robots built to aesthetically resemble humans.
same like humanoid robots, animaloid robot are robots with animal shape, most animaloid robots are four legged which resemble dog's shape or horse. mostly because they are easier to make
Line-following robot
Some of the earliest Automated Guided Vehicles (AGVs) were line following mobile robots. They might follow a visual line painted or embedded in the floor or ceiling or an electrical wire in the floor. Most of these robots operated a simple "keep the line in the center sensor" algorithm. They could not circumnavigate obstacles; they just stopped and waited when something blocked their path. Many examples of such vehicles are still sold, by Transbotics, FMC, Egemin, HK Systems and many other companies
The Denning Mobile Robot Company of Boston was the first company to offer ready-made autonomous robots that were subsequently purchased primarily by
researchers. Grinnell More's Real World
Interface, Inc.
(RWI) and James Slater's Nomadic Technologies (US), along with Francesco
Mondada's K-Team (Switzerland), were other pioneering companies in this field,
addressing the need for ready-made robots for use by robotics researchers. RWI
created the B-21, Nomadic the XR4000, whilst the tiny Khepera mobile robot
emerged from the stables of the Swiss K-Team. However, the high price of these
machines meant that only a few graduate students and military researchers could
afford them. Eventually, the low-cost Pioneer robot was introduced in 1995
(from a collaboration between RWI and ActivMedia
Robotic), a
project that expanded research in mobile robotics due to the affordable price.
