A mobile robot generates position error when it changes directions. To reduce the position error a gyro sensor can be used. However, the effect of gyro sensor is not fully measured precisely for various conditions. This paper focuses on the effect of gyro sensor by measuring position error which is comprised of angular error a nd distance error. In the experimentation, the position errors of mobile robots for five different courses are measured for the robot w ith a gyro sensor and those without it. The closed courses include t hree, five, seven, nine and eleven direction changes which cause to generate considerable position errors. The experimental result shows t hat the angular error is reduced to about 14.3%~41.4% aftera gyro se nsor is used. Further, the position errors in distance are reduced to 22.4~31.8% when a gyro sensor is used. The remarkable differe nce between the two kind of errors is that the angular error incr eases steadily whereas the distance error increases rapidly but doe s not increase anymore over a certain level as the number of direct ion change increases. © 2015 SERSC.
