Abstracts: A wall-crawling robot or other electro adhesive device can include a battery or other low voltage power source driving a motor that provides a primary device function, a voltage convertor adapted to convert the low voltage to a high voltage using the motor output, and electrodes configured to apply the high voltage to produce an electrostatic force between the electro adhesive device and a foreign substrate. The electrostatic force maintains a current position of the electro adhesive device relative to the foreign substrate, and the voltage convertor is separate from the primary function of the electro adhesive device. the primary function can be a mechanism for locomotion, and the voltage convertor can be a van de graff generator, a piezoelectric generator, or an inductive switch generator, any of which are driven in a secondary manner as a result of the motor output.
