Planar Robots Dead-reckoning with Optical Flow, Wheel Encoder and Inertial Measurement Unit
19 Oct 23
Systems and methods provide for estimating a trajectory of a robot by fusing a plurality of robot velocity measurements from a plurality of robot sensors located within a robot to generate a fused robot velocity based on the accuracy of those robot velocity measurements and applying Kalman filtering to the fused robot velocity to compute a current robot location.

Utility
Gyroscope and Optical Flow Sensor Scale Calibration
22 Sep 22
A method for calculating a scale factor for a gyroscope can include detecting, by a gyroscope, a physical motion of a robot, detecting, by an optical flow (OF) sensor (and/or camera), one or more image signals including information; and deriving estimates of sensor calibration parameters based on the detected physical motion and the information.

Utility
Methods and Apparatus for Calibrating the Zero Rate Output of a Sensor
27 Jan 22
A method for calibrating zero rate offset (ZRO) of a first inertial sensor located on a device, the method includes determining a stability level of the device based on information associated with at least one non-inertial sensor located on the device; and performing a calibration of the ZRO of the first inertial sensor when the stability level is above a threshold.
