Title:
ROBOT USING MAGNETISM TO ACHIEVE DIRECTIONAL POSITIONING
Document Type and Number:
WIPO Patent Application WO/2019/047582
Kind Code:
A1
Abstract:
A robot using magnetism to achieve directional positioning comprises a robot body, mounted at the bottom of the robot body are: multiple Hall effect sensors (6) forming a circle or a II shape in order to acquire a directional landmark on the ground, the directional landmark is composed of at least two magnetic strips of different polarities; an address landmark identification device. The address landmark identification device acquires an address landmark on the ground (5). The multiple Hall effect sensors and the address landmark identification device are connected to a robot body controller. The robot body moves forwards or backwards or turns according to an instruction and the acquired directional landmark and address landmark. The Hall effect sensors are mounted close to the ground. A low remanence/high permeability material plate (7) is fixed above and near to the Hall effect sensors. The shape of the low remanence/high permeability material plate matches the shape formed by the multiple Hall effect sensors. The invention has a simple structure and low cost, is reliable and accurate in positioning, and is easy to maintain.
