A microelectronic controlled magnetic cleaning system, comprising a micron-scale fine line inner-end part, a micro-scale fine line outer motor control part, and a micro-scale fine line outer system electronic control part. The micron-scale fine line inner-end part is manufactured as a plurality of micron-scale magnetic fine lines, wherein the central magnetic fine lines are slightly wider than the periphery magnetic fine lines. The inner-end part of the central magnetic fine lines is spiral shaped. The micro-scale fine line outer motor control part is made by adding a high-precision micro-motor at the middle portion outside the central magnetic fine lines, When a larger obstruction is found by an endoscope or other optical device imaging system, the central magnetic fine lines can be controlled to arrive at a designated position, and motor speed can be controlled to clean the obstruction. Also disclosed is a micro-electronic controlled magnetic cleaning method.

Microelectronic controlled magnetic cleaning system and method thereof

A gyroscope-based system and method is disclosed. Image information data is collected; a mechanical arm working environment image is modeled; a heat source supply apparatus and a gyroscope are provided at the mechanical arm proximal end; the position of the proximal end is accurately measured by accurately tracking the heat source at the proximal end; the relative position of the mechanical arm distal end is accurately calculated by using high-precision angle information measured by the high-precision gyroscope in combination with a number-theoretic formula. The disclosure provides separately determining the position of the distal end, or for assisting other algorithms or apparatuses that track the position of the mechanical arm distal end in error correction and calibration of the position of the mechanical arm distal end. The position of the mechanical arm distal end can be continuously and dynamically tracked in real time, and virtualized in the corresponding image system.
