Foreword (1) In embedded programming, we often need to store data from various sensors. Most of the time sensors, such as infrared light sensors, return data that is either 0 or 1. Therefore, only one bit is needed to store it. However, many people often use char array storage, so that only one-eighth of the […]

## if/switch statement and for loop while&to….while in JS

In any programming language, it is necessary to support three types of process control required to satisfy program structuring: Sequence control Branch control (conditional control) loop control Sequential control: In program flow control, the most basic thing is sequence control. The program will be executed in top-down order. if statement (commonly used statements in JS) […]

## [Lie group Lie algebra] [manif] 2D robot positioning based on fixed beacons (Error State Kalman Filter)…

demo demo operation result We consider a robot on a plane surrounded by a small number of punctual landmarks or beacons. The robot receives control actions in the form of axial and angular velocities and is able to measure the position of the beacon relative to its own reference frame. The robot pose X is […]
