Users can apply available Eigen algorithms directly to the mapdata for versatile and efficient data manipulation. This repository consists of following packages: grid_map is the meta-package for the grid map library. The grid map filters are based on ROS Filters, which means that a chain of filters can be configured as a YAML file. I assisted in creating a custom ROS2 fleet management software for autonomous boats and have integrated MoveIt2! You can specify the build type by setting. The number is often 0 (free space) to 100 (100% likely occupied). moderate (7) Length: 5.0 km Est. Multi-layered: Developed for universal 2.5-dimensional grid mapping with support for any number of layers. Select which layer to transform as points with the layer parameter. to follow the robot) without copying data in memory. See EigenLab for the documentation of the expressions.
