Abstract
In petrochemical plants, there are a large number of steel pipes running horizontally, vertically, and obliquely, and inspecting them is difficult and time-consuming. There is therefore a strong demand for practical pipe inspection robots to aid in this task. The aim of the present study is to develop an outer-pipe inspection robot that can move along narrow pipes and wires. Simulation model of mobile robot was developed. The simulation model consists of motion equation. This model has 8 degrees of freedom. Identification of the simulation model was conducted with the mobile robot. Using this model, we evaluate effects of center of gravity on the running stability. The procedure of calculate is Runge-Kutta method. It confirmed that pitch vibration is suppressed by moving center of gravity.
