The paper “ The Development and Designing of Legged Robots”   is an impressive variant of literature review on engineering and construction. Legged robots are a type of robot, which is designed to move from one place to another. In fact, these robots are also termed as mobile robots or walking robots. These legged robots are mostly using four legs and six legs, but there are developments that have resulted in the designing of a two-legged robot which is more or less like a human being. The development of robots is one of the fascinating research topics in the fields of engineering.

There have been developments in improving the design and architecture of robots. The legged robot or walking robot is one of the advancements in the engineering of robots (Warnakulasooriya et al. , 2012, p. 1017). Robots exist in different types depending on their application, morphology, and locomotion. The development of legged robots has been majorly influenced by the lack of locomotion in previous robots. Most of the previously developed robots were not able to explore different terrain. The previous robots were designed using wheels hence could not navigate in some terrain limiting their movements and locomotion.

This means that the legged robot was able to climb mountains and move up and down staircases. The success in biped robots is in the development of Topio and Nao which are biped Robots. These robots are able to sing, play, and move from one place to another. However, one of the challenges in building robots was to ensure the balance of the robot, especially for the two-legged or biped robots. Engineers were faced with the difficulty of balancing the weight in the two-legged robots while the robot was kicking as well as when the robot is walking or running.

Moreover, there was also a need to develop control systems that would allow users and engineers to control the robot in different strategies. With the advancement in electronic engineering, it is now promising that two-legged robots can be easy to develop in terms of balance and weight (Mendez et al. , 2008). Purpose Statement (Thesis)The development of robots has been focusing on developing robots with more than two legs in order to maintain the balance of the robot during walking and locomotion.

The purpose of this paper is to discuss the building of a simple two-legged robot that is capable of walking and kicking as well as maintaining its balance (Mota et al. , 2010, p. 1661). In discussing the biped, the paper will focus on key areas such as the design and development and programming of the two-legged robots. The various activities and processes involved in the design and development as well as programming will be discussed.

This development is mainly triggered by advancements in technologies especially in electronic engineering. In designing the robot, the hurdles included will consist of a selection of the building materials, material thickness, materials need in the joint selection and assembly tolerance. In the programming section, the paper will discuss the pseudo sequences involved in walking and kicking of the robot. Literature ReviewThe developments in technology have resulted in the designing of more autonomous robots which are offering different benefits to human beings. According to Mendez et al (2008), developing a two-legged robot is complex since the engineer has to consider the aspect of balance and control during locomotion.

This is compared to the existing wheeled robots which were easy in maintaining balance during movement. Legged robots should undergo certain modifications in order to achieve gaits that are coordinated. Although the field in robot building has witnessed tremendous development, the limitations in balance and control systems have not been exploited fully (Roy & Pratihar, 2013, p. 401). With the current status of technology, it is required that biped robots should be able to walk in a straight line by following programmed commands.

According to Roy & Pratihar (2013), the bipedal is designed in order to perform variety of tasks that require them to have balance. For example, these Nao and Topio robots are used as a form of entertainment. In addition, the biped robots are used in walking legs technology to assist the individual with a single leg (Mendez et al. , 2008).
