2016-11-01 13:09:32 -0500 asked a question robot_arm not moving in Moveit but is moving in Gazebo

HI! everyone! I have a robot model,and i want to get the joint_trajectory form moveit!,I use the Gazebo to publish the arm controller. Everything looks good,but When i set the goal and use plan and excute.Robot_arm not moving in Moveit but is working in Gazebo.

I think it is the problem about the topic /joint state did not receive anything.But I have another topic named robot/joint state published by arm controller or gazebo. I already saw the same problem but i still did not know how to solve this problem.

There have another problem after moveit compute the trajectory. Moveit always showed the warning : Controller /utlr_arm_controller failed with error code GOAL_TOLERANCE_VIOLATED Controller handle utl/r_arm_controller reports status ABORTED

In some articles tell me add the <param name="allowed_goal_duration_margin" value="5.0"/>,but it did not work!

Please help me to solve these two problems! and thanks for any help! I can provide any file you need to check! attach is the picture about the problem:picture

Hi ! I just see the email this weekend,i so sorry for reply too late.If you want to use this package,you just need to sudo apt-get install ros-indigo-serial .Then you can use serial like in python or c++,just like #include <serial serial.h="">.

If i have one end effector on the arm ,should i add this link in the controllers.yaml? but the end effector do not have any joint

HI! everyone I'm working on a ROS-Industrial package for my own robot,and i follow Industrial/Tutorials to create my moveit_planning_execution.launch everything works perfect.

when I give the command to execute, I get the following error like this problem Moveit execution fails - invalid joints I had already check my joint,but i can not find the problem.


here is my controllers.yaml

controller_manager_ns: joint_trajectory_controller
controller_list:

type: FollowJointTrajectory
joints: 
  - R_arm_joint1
  - R_arm_joint2

  - R_arm_joint4
  - R_arm_joint5
  - R_arm_joint6

joints: 
  - L_arm_joint1
