Key factors analysis of wall-climbing robot

A kind of negative pressure wall-climbing robot was proposed. Analysis the relationship between speed of vacuum motor and negative pressure which based on courses of pressure form and pressure keep, and found that interspace height between airproof gasbag and wall was the key factor influencing on the stability of robot. The pressure distribution which between airproof gasbag and drive wheels shows relationship with negative pressure, pressure coefficient, weight, airproof gasbag friction coefficient and airproof gasbag friction coefficient. Analysis locomotion mechanism of robot from swerve performance. Experimental results validate the theory.
