Speed Calibration for Mobile Robot As Prototypes to Smart Vehicles

Abstract

Mobile robots are robotic systems that exist with features such as mobile capabilities, autonomy and perception. Autonomous mobile robots such as robot cars have the disadvantage of not being able to control the velocity when moving in a corner area. The purpose of this study was to find the appropriate calibrated velocity value for the robot car to slide in various environmental conditions such as straight lines and corner paths. The study was conducted using Arduino board hardware, remote robot cars, remote controls for remote robot cars, and rotary encoders. Three main experiments were completed to test the calibrated speed values, namely first test on straight line, test on corner lane, and last test on combination of straight path & corner lane. Simulations for road routes are also made using cardboard, sandpaper and carpet. The results of experimental analysis found that as the speed of a robot car increases, the longer it takes to make a single wheel rotation.
