This document describes an automatic trolley system for material handling in industries. It discusses how material handling equipment is used to move, store, control and protect materials throughout the manufacturing process. It then explains how an automatic trolley was developed using electric motors, a power transmission system, and sensors to carry and drop off materials autonomously on rough surfaces. The trolley provides benefits like increased accuracy over manual methods, reduced lead times, elimination of manual labor, and compact size, though it has higher maintenance costs and risk of electronic failures.
