4.2 PUGH CHART

4.3 Justification for Selected Concept

Concept 1 has been selected based on its overall performance in the PUGH chart. The bot can be manufactured on a lower budget with lesser number of parts to be fabricated. It is convenient to use due to its simple mechanism and architecture. Due to the presence of wheels, the bot has smooth motion which enhances the quality of pattern drawn. The light weight of the bot makes it easily portable.
