Stage controller tutorial on Groovy
I'm trying to follow the stage controller tutorial here: ros.org/wiki/stage/Tutorials/IntroductiontoStageControllers.
However, I run into the following errors:
err: Model type laser not found in model typetable (/tmp/buildd/ros-groovy-stage-1.6.7/debian/ros-groovy-stage/opt/ros/groovy/stacks/stage/build/stage/libstage/world.cc CreateModel)
err: Unknown model type laser in world file. (/tmp/buildd/ros-groovy-stage-1.6.7/debian/ros-groovy-stage/opt/ros/groovy/stacks/stage/build/stage/libstage/world.cc CreateModel)
I replaced laser with ranger in roomba-wander.world and got the following warnings:
warn: lookup of model name roomba.ranger:1: no matching name (/tmp/buildd/ros-groovy-stage-1.6.7/debian/ros-groovy-stage/opt/ros/groovy/stacks/stage/build/stage/libstage/world.cc GetModel)
warn: Model roomba.ranger:1 not found (/tmp/buildd/ros-groovy-stage-1.6.7/debian/ros-groovy-stage/opt/ros/groovy/stacks/stage/build/stage/libstage/model.cc GetChild)
Segmentation fault (core dumped)
Now I read this topic, answers.ros.org/question/33973/stage-error-in-fuerte/, but the solutions are for fuerte. I tried them anyway, but it doesn't work. Is there a way to fix this? Or is there another similar tutorial that I could follow? I need to simulate a navigating robot (I will use an icreate), and eventually implement SLAM.
