Design of a train cleaning robot for the train carriage interior

Abstract

This paper describes the design of a robot platform that can collect and disposing waste in passenger trains. It covers an analysis of the key design considerations for success in operating in a train environment, as well as considerations in manipulating waste in an often-confined space. The design constraints are analyzed for their importance in the successful development of a train cleaning robot. The analysis informs the development of three robot designs. These designs are assessed in their appropriateness for development against a baseline design that uses readily available parts. Among the three designs developed, one uses a vacuum powered arm similar to the type utilized in manufacturing plants, one is based on the dustpan and brush used in domestic cleaning, and one is based on a conveyor belt. These designs are assigned a percentage suitability for implementation in the automated train carriage cleaning system. Using the key values and the requirements the design should fulfil, a systematic investigation is undertaken. This investigation finds the conveyor belt design most appropriate for application due to the sustainable design and effective cleaning that can be undertaken without additional tools.
