        This paper introduces the new concept of a gripper mechanism mounted on the home cleaning robot. This new mechanism composed of two grippers and an auxiliary dustpan can tidy and load up objects. We additionally analyze the required motor torque and dynamic motion of this robot using dynamic simulation of Recurdyn. This new tidying gripper mechanism is expected to be used in various home cleaning applications.

        This paper presents a rope modeling and verification for the robotic platform of the wall cleaning robot (ROPE RIDE). ROPE RIDE has the characteristics of climbing up and down using a rope fixed on the roof like traditional workers. In order to perform a stable operation with a wall cleaning robot, it is necessary to estimate the position of the robot in a vertical direction. However, due to the high coefficient of extension and nonlinearity of the climbing rope, it is difficult to predict the behavior of the rope. Thus, in this paper, the mathematical modeling of the rope was carried out through the preliminary experiment. Extensive experiments using different types of rope were used to determine the parameters of the constitutive equation of climbing ropes. The validity of the determined parameters of various ropes was verified through the experiment results.

        In this paper, we introduce the pipe cleaning robot developed to clean the gas impurities of the iron manufacturing equipments. The pipe cleaning robot is composed of two driving modules and one cleaning module. 2-DOF joint units were developed for connections among the modules. To maximize the traction power of the driving parts, it became caterpillar type. The extension links have been developed to maintain the traction force in case the pipe inner diameters change. Three cleaning modules were developed for the effective cleaning in the pipe. The driving and cleaning performance tests of the pipe cleaning robot were proceeded in the field of the iron manufacturing equipments.

        In this paper, developing of a pool cleaning robot is addressed. First, we analyze commercial pool cleaning robot mechanisms, and the merits and demerits of wireless version of a pool cleaning robot is introduced. And then the water-jet moving mechanism for a pool cleaning robot is proposed to improve energy efficiency and mechanical design advantage, which is one of the strong candidates for wireless pool cleaning robots. Next, the method of cleaning performance evaluation of pool cleaning robots is firstly defined with five key factors, and it was verified by experimental results. If the cleaning performance can be quantitatively defined, we can design optimally a pool cleaning robot, which results in the cost down.

        This paper presents a graphic user interface system consisting of graphic simulator and remote control system for a building cleaning robot. It provides a tool of convenient 3D graphical map construction for real world. The 3D map is reconstructed from existing 2D building CAD data with DXF format by using OpenGL graphic API. Through this system, graphic display of robot's status information, remote control and cleaning scheduling can be done for a building cleaning robot. This proposed system is expected to give efficient way of graphic simulation and remote monitoring and control system for a building cleaning robot.

        Recently researches on the window cleaning robot are being conducted actively. Moving mechanisms of these window cleaning robots are divided into two categories, which are towed type and walking type. Towed type is focused on fast cleaning on the flat surface of building and walking type has priority on cleaning task on relatively complex surface with overcoming obstacles. Currently commercialized towed type window cleaning robot has weakness that it is hard to adhere closely with the wall and easy to be affected by wind. In case of walking type it has the problem that the position errors are continuously accumulated during motion. In this paper, we propose new towed and walking type mechanism which can compensate previous weaknesses. After that we estimate the performance of each proposed mechanism by simulation.
