A Wall Climbing Robot Based on the Improved Electro Adhesion Technology

Abstract

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.
