Abstract
Simple delivery robot system was made to make daily activities easier because the robot can deliver things to another place as long as it is in the same floor and has line mapping. This research is different from previous line follower research; the robot used has a dimension of 40 cm (length) x 40 cm (wide) x 40 cm (height), it can be summoned from several rooms using RF remote and can be ordered to deliver things and send messages. The robot uses seven infrared sensors to trace the line which is within 1.5 cm from underneath its body. In this research, the robot can go to four designated rooms plus one base camp. The robot also has several features i.e.: alarm system which can indicate when the robot arrived at the destination, LCD and keyboard so the user can write message, obstacle sensor to avoid crash, and emergency system which will active when the robot stray out of the line. The emergency system activates video camera and alarm so the user can control the robot with remote control to position it back in the line map. All activities are controlled by microcontroller AT89C51. The focuses of this research are robot mapping system using line mapping, special remote system using radio frequency, message delivery system using LCD and emergency system using video camera and remote control. Maximum speed of the robot is 1.045 m/s, and it can accommodate maximum load of 3.5 kg.
