Design and Implementation of Smart Forklift for Automatic Guided Vehicle Using Raspberry Pi 4

Automatic Guided Vehicle (AGV) pallet truck is widely used in the industry. This kind of AGV such a combination ordinary forklift mechanism. The mechanism employed for lifted up or carrying things from one place to another place. As technology has been developed along with industry revolution 4.0, therefore, activity could be done automatically by using robot-like truck. Basically, working principle similar whereas operated. DC motor applied as driving force uplifting and down lifting process chosen because it large torque which advantageous loads. Unfortunately, also owns some disadvantages high maintenance fees less precision. study proposes smart trucks that utilizes stepper ultrasonic distance sensor. equipped raspberry pi model B main microcontroller combined an result sensor error approaching zero percent so precision height can fully controlled. Step / Revolution (SPR) method makes move smoothly like micro-step number rotations controlled we want.
