2017-03-04 14:25:20 -0500 | asked a question | No Laserscan received for many seconds for navigation ? Hi Guys, I m trying to set up the 2D Navigation Stack. Everything works fine beside of the integration of the laser_scanner. I set up all the transformations as well as publishing all the needed data as map, odom and laser_scan for autonomous navigation. Nevertheless amcl is always saying this:
I have been working with ROS now over 2 years and i dont understand this mistake. My tf_tree (map->odom->base_link->laser_scanner) doesnt show any errors as well as all published topics show the status ok in rviz. If I m using the fake_amcl node everything works fine. Does anyone know what I can do ? The advice that i found here, to set the sim_time to true causes that amcl isnt loading the map. Thanks for help :) |

2015-05-20 04:45:08 -0500 | asked a question | How does the Arbotix-Board controlls Dynamixel? Controll-Structure? Hello everyone, i m trying to understand how the Arbotix-Board controlls the Dynamixel-Motors. Is there allready set a controll structure like in http://wiki.ros.org/ros_control stack? How does that work? How does Arbotix-Board plan a trajectory to execute ? Whiche messages are beeing send between them during controll the motor speed? Thank you for help!! |
2015-05-05 06:00:10 -0500 | asked a question | How does the information chain looks like in the motor control Hello everybody, i want to find out how ROS generates new motion control orders for example by dynamixel motors. How does the infromation chain looks like? In addition i put the overview picture for the navigation stack used in Turtlebot. Can anyone explain me how the base controller exactly works? i just get him velocity commands to interact with the local planner ![image description] ( http://wiki.ros.org/navigation/Tutori... ) |
