Problems solved by technology

[0003] ①Small driving stroke
Since the size of the electrostatic adsorption force is inversely proportional to the adsorption distance, in order to maintain a certain adsorption force, it is necessary to control a smaller distance, resulting in a smaller driving stroke
[0004] ②The driving speed is slow
The generation and elimination of electrostatic adsorption depends on the transfer of charges, so there is a response time, that is, dielectric relaxation time, which limits the speed at which electrostatic adsorption can be used to drive motion
[0005] ③Complicated driving structure
In order to convert the linear motion of the driver into the motion of the overall motion device, it is usually necessary to use an elastic recovery mechanism and a displacement amplification mechanism, etc., which makes the structure of the driver more complicated.

Abstract

The invention provides a rotary electrostatic adsorption driver which comprises a driver body, and the driver body is a cylinder formed by a first outer frame, a second outer frame and a plurality of electrodes. Two ends of the electrodes are respectively inserted into holes of the first outer frame and the second outer frame and are fixed; the plurality of electrodes are uniformly distributed between the first outer frame and the second outer frame in the circumferential direction; the power supply assembly can supply power to the electrodes; the driver body is arranged on the supporting plane, an electrostatic field is generated between the electrode and the supporting plane, the electrode is subjected to electrostatic adsorption force, the driver body rotates on the supporting plane under the action of the electrostatic adsorption force, the driver can directly drive the rotating motion through torque generated by adsorption, and therefore redundant structures are reduced.

Description

technical field [0001] The present invention relates to a driver provided by the present invention, which uses electrostatic adsorption force as a driving force, and can realize rolling in a specified direction (or according to a specified trajectory) by means of the electrostatic adsorption force between it and the ground (or track surface). It can be used to make toy models, demonstration props, and used in complex mechanical flaw detection, medical micro-drug targeted delivery, unknown environment detection and other scenarios. Background technique [0002] The so-called static electricity is a static charge or a non-flowing charge (the flowing charge forms an electric current). Static electricity is formed when charges are accumulated on an object or surface, and charges are divided into positive and negative charges, that is to say, electrostatic phenomena are also divided into two types, namely positive static electricity and negative static electricity. Positive stat...
