摘要：A low cost service robot was designed and implemented specifically to be used in service industries e.g. hotels. This service robot can deliver a requested payload (towels, bed-sheets, drinks or toiletries) to a customer. As evident with modern technology, robots are assisting man in several avenues of the service industry. This designed service robot can propose an error free service, work around the clock and consume less time with requested tasks. The prototype can handle two commands received from two different rooms simultaneously. It has the ability to choose to always deliver to the closest room from its base first. Also, it has the function to carry two different types of payloads in two of its compartments and to lift up the desired payload ordered by the customer using a scissor lift system. The service robot also uses a touch screen to interact with the customer. The algorithm of the design ensures that the payload will always be delivered to the right customer in due time.
