Answer by spmaniato for I have a differential robot, with a laser Hokuyo, and I want my robot to cover the whole part of a map. I saw that there is some algorithms but I can't find a code. So have someone already implement such algorithms? Thank you

The heatmap package (http://wiki.ros.org/heatmap) says it does coverage path planning as part of its functionality. The source code is here and looks maintained: https://github.com/eybee/heatmap/tree/jade-devel The heatmap package itself uses the coverage path planner from the Auburn Autonomous Lawnmower stack (https://github.com/Auburn-Automow/au_automow_common), which looks out of date.
