Search string "descriptions the class differential with base class type nav2_amcl::MotionModel does not exist. Declared types are nav2_amcl::DifferentialMotionModel nav2_amcl::OmniMotionModel"
johnpenright commented on Jul 5, 2022 So I've made some progress. In the robot param file (waffle_pi.yaml), if I change line 29 from robot_model_type: "differential" to robot_model_type: "nav2_amcl::DifferentialMotionModel"
then rViz will launch and initialize properly.
However I don't seem to be getting a local costmap, even though rViz is confugured to display one. I'm not seeing any clear errors in the logs.
Fix
param$ pwd /opt/ros/humble/share/turtlebot3_navigation2/param param$ sudo cp waffle.yaml waffle.yaml.org [1]- Done emacs waffle_pi.yaml param$ sudo emacs waffle.yaml& [3] 5401 param$ diff waffle.yaml waffle.yaml.org 29c29 < robot_model_type: "nav2_amcl::DifferentialMotionModel" --- > robot_model_type: "differential"
Status
There is no cost map.
