Could not connect to action server - Could not execute trajectory #240

Open manujtrehan opened 5 years ago

manujtrehan commented 5 years ago

I was trying to control my robot model and make it follow a cartesian path using ros_descartes. However, while trying to execute the code, I get the following errors:

[ WARN] [1560596479.774029295]: Nominal time value must be greater than or equal to 0.0
[ INFO] [1560596479.785635458]: Computed path of length 10 with cost 4.097252

Can someone please help me with solving this issue?

Test env : 18.04 melodic It was old one but I solve by changing controller.yaml file from

controller_list:
  - name: ""
    action_ns: joint_trajectory_action
    type: FollowJointTrajectory
    joints: [joint_1, joint_2, joint_3, joint_4, joint_5, joint_6]

to 

controller_list:
  - name: ""
    action_ns: joint_trajectory_action
    type: FollowJointTrajectory
    joints: 
      - joint_1
      - joint_2
      - joint_3
      - joint_4
      - joint_5
      - joint_6
