Abstract Inspired by gecko’s adhesive feet, a wheeled wall climbing robot is designed in this paper with the synchronized gears and belt system acting as the wheels by considering both motion efficiency and adhesive capability. Adhesion of wheels is obtained by the bio-inspired adhesive material wrapping on the outer surface of wheels. A ducted fan mounted on the back of the robot supplies thrust force for the adhesive material to generate normal and shear adhesion force whilemoving on vertical surfaces. Experimental verification of robot climbing on vertical flat surface was carried out. The stability and the effect of structure design parameters were analyzed.

Purpose The purpose of this paper is to describe the design and development of “Pylon-Climber II”, a 5-DOF biped climbing robot (degree of freedom – DOF) for moving on the external surface of a tower and assisting the electricians to complete some maintenance tasks. Design/methodology/approach The paper introduces a pole-climbing robot, which consists of a 5-DOF mechanical arm and two novel grippers. The gripper is composed of a two-finger clamping module and a retractable L-shaped hook module. The robot is symmetrical in structure, and the rotary joint for connecting two arms is driven by a linear drive mechanism. Findings The developed prototype proved a new approach for the inspection and maintenance of the electricity pylon. The gripper can reliably grasp the angle bars with different specifications by using combined movement of the two-finger clamping module and the retractable L-shaped hook module and provide sufficient adhesion force for the Pylon-Climber II. Practical implications The clamping experiments of the gripper and the climbing experiments of the robot were carried out on a test tower composed of some angle bars with different specification. Originality/value This paper includes the design and development of a 5-DOF biped climbing robot for electricity pylon maintenance. The climbing robot can move on the external surface of the electric power tower through grasping the angle bar alternatively. The gripper that is composed of a two-finger gripping module and a retractable L-shaped hook module is very compact and can provide reliable adhesion force for the climbing robot.

Electro adhesion is a novel adhesion technology, offering a new method for the designing of adhesion type of climbing robot. In this paper, an improved electro adhesion technology is put forward, using ERG (Electro Rheological Gel) as the insulating layer of electrode array. Experiments show that the adhesion force is enhanced by using ERG and the electrode array has self-cleaning function to some extent. Finally, a climbing robot was developed and it can climb kinds of walls (such as wood, glass and concrete), which proves the effectiveness of the improved electro adhesion technology.

In order to satisfy the requirements on payload ability and maneuverability of the wall-climbing robot, a novel permanent magnetic adhesion system based on the linear Halbach array is designed. The permanent magnetic adhesion system and the wheel locomotion mechanism are employed in the robot system. By static and dynamic force analysis of the robot, design requirements about adhesion system are derived. The optimal dimensions of the mechanism are obtained using numerical modeling and parameter approximation method of first order partial derivative of dependent variables. Finally, the adhesion mechanism has been constructed and the maximum and minimum adhesion forces are measured and compared with numerical simulation and a good agreement is found.
