Map building and localization are two crucial abilities that autonomous robots must develop. Vision sensors have become a widespread option to solve these problems. When using this kind of sensors. the robot must extract the necessary information from the scenes to build a representation of the environment where it has to move and to estimate its position and orientation with robustness. https://www.markbroyard.com/super-pick-top-bar-hive-starter-kit-fashion-super-choice/
