Autonomous mobile robot using programmable logic controller

Automation is very synonym to robotics. Automation is a sequence of operation that uses inputs to generate outputs that contain less or no human interruption. The term ‘Robotic’ is a science of designing and building a suitable instrument that is used for real-life applications whether in an automated manufacturing or non-manufacturing environments. Meanwhile ‘Robot’ is an instrument that is built by human to perform various tasks of operations continuously and precisely for human welfare. The work is done in an integrated manner resulting in increased of productivity with a guaranteed quality of output product. In the era of technology, robots are commonly used in almost all activities whether in industries or even at home. The development in robot technology has increased gradually as the time passes. Nowadays most robots are intelligent whereby they have “brains” that can sense the presence of input variables, map or locate the source of presence factor, plan for further step of actions and act according to the program being set by the programmer or Sense, Map, Plan and Act (SMPA) theory of operation [1]. It has many parts that are combined and connected together to become a complete instrument and equipment suitable to the given task or job.
