This document describes the sections and components of an automated trolley project: 1) The power section supplies 12V battery power to the project components through a switch and voltage regulator. 2) The sensor section uses IR sensors, a potentiometer, and comparator to sense a black line path and uses ultrasonic and color sensors to detect obstacles. 3) An Arduino controls the process by reading sensor inputs and sending commands to the driver section. 4) The driver section consists of relays and DC motors, using a motor driver circuit to provide sufficient power to move the motors based on Arduino commands.
