SYSTEM AND METHOD FOR RF BASED ROBOT LOCALIZATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17938300 titled 'SYSTEM AND METHOD FOR RF BASED ROBOT LOCALIZATION
Simplified Explanation
The patent application describes a method for determining the trajectory of a handheld device in motion within a service area to be traversed by a robot. The method involves obtaining ultra-wideband (UWB) ranging measurements between the handheld device and multiple anchors in the service area, as well as image data and inertial measurement unit (IMU) data. The trajectory is determined based on the UWB ranging measurements, and then adjusted using image features from the image data and motion estimates from the IMU data. The adjusted trajectory is identified as the boundary of the service area.
- Obtaining UWB ranging measurements between a handheld device and anchors in a service area

Original Abstract Submitted
A method includes, when a handheld device is in motion within a service area to be traversed by a robot: obtaining ultra-wideband (UWB) ranging measurements between the handheld device and multiple anchors located in the service area; and obtaining image data and inertial measurement unit (IMU) data. The method also includes determining a trajectory of motion of the handheld device based on the UWB ranging measurements. The method also includes adjusting the trajectory based on image features obtained from the image data and motion estimates obtained from the IMU data. The method also includes identifying the adjusted trajectory as a boundary of the service area.
