The essence of wall climbing robot research is the selection of adhesion and locomotive mechanism. Electrostatic adhesion (ESA) technique is chosen based on qualitative advantages. The parallel-plane capacitor model and comb electrode model both form the principles for ESA actuation mechanism. However these theoretical models are not validated. Preliminary tests with flexible printed circuits (FPCs) and Sample A both revealed the qualitative nature of the ESA phenomenon. It was found that the ESA force measured in experiments did not resemble the simulation values. Therefore parametric investigations were carried out, as to design and experiment with the thin film electrostatic adhesion actuators (TFEAAs) by isolating and controlling the test parameters. Dominant parameters that contribute to ESA force were identified. The evidence from these repeatable experiment results could develop towards a new empirical model for ESA actuation mechanism.
