A mini forklift robot

This paper presents the design of a mini forklift robot that can store and pick up object to/ from specified storage slot from/ to a base using line follower and RFID. Currently, in warehouse storage systems are mainly still done in a traditional way using human operator to store and pick goods into specified location. This project is intended to construct an autonomous mini forklift robot that use using Radio Frequency Identification Devices (RFID) technology to find the coordinates of targeted storage slot and goods identification. The control of movement consist of DC Motor with Pulse Width Modulation and infrared sensors for the line follower. The programming operation was performed by C language using Visual Studio 2005, CodeVisionAVR 2.05, and SQL 2005 as database. The program on the computer can serve two purposes. Firstly, program can check, read, write, and erase data on RFID Tags. Secondly, program can ask a mini forklift robot to store and pick goods at specified location. The robot can recognize two sides (A and B), 128 lines, 16 columns and 16 rows cabinets. The total of success achieved was 100% in storing goods but 58.33% in retrieving goods, because robot fails parking correctly to the base.
