This paper presents a column-climbing robot with a mechanical manipulator, which can spirally go up and down a column using wheels. The developed robot can do useful works using the manipulator at the top of a column, e.g., electric pole while communicating wirelessly with an operator panel. It is driven using a battery without any power cables, and the average duration of power is at least one hour. The robot has a function to detect a work object using an optical sensor installed at the bottom of the manipulator. The spirally column-climbing robot developed is demonstrated by experimental works and also by showing it at an exhibition.

Maintenance works of offshore wind turbines could take a longer time, which causes the reduction of their energy production efficiency, than those of onshore wind turbines owing to severe offshore environment. Subsequently, preventive maintenance measures are required to increase the production efficiency. Thus, we proposed a wheel-based Underwater Pole Climbing Robot (UPCR) platform, which was aimed at the periodic inspection and maintenance of the substructures of the offshore wind turbines, with three advantages: high speed, good mobility and low power consumption. In the proposed platform, a self-locking system using a gripper module was adopted for preventing slippery problem and a dual configuration was chosen for moving on a branched structure. As a result, the proposed robot was able to continuously climb, preserve it's position at the pole without consuming energy, and move from the pole to the other branched pole. The results of this research show that the UPCR has basic moving capabilities required for the underwater work for the substructures of the offshore wind turbines.

Mobile Robot climbing stairs needs high power and high efficiency. one of the high power type motor is Transverse Flux Motor (TFM). Moreover, TFM is a high force density per volume. We analyzed a characteristic for the TFM and simulated the parametric research of the TPM by using 3D FEM solutions. It presents to design the basis of the TPM. design parameters are Radius of outer rotor, pole height, pole depth, pole depth, airgap, and Magnetomotive force.
