Velocity or Position wrong in ROS Moveit ?
Hello every one. I have worked with ROS for a few days. I am trying to use ROS to control trajectory tracking in my 6 DOF robot. I used velocity and position which ROS return to run our 6 drivers. However, i think these values have some problems, i saw in the below picture (i get value from ROS topic execute/goal and draw it by python). The time when velocity <0 to >0, i noticed that maybe something wrong happened with position value. Becase before velocity = 0 , i think position need to increase value and when velocity > 0, position will go follow the opposite direction.
Have anyone work with these 2 values ? Could you please show me what wrong in my situation ?
Thank you very much !!![image description
you do now, and seeing as it's virtually impossible to understand what you are referring to, please edit your question to add the plots.
Thank you! i will add the picture
It's not terribly important, but I'm used to plots where time is on the horizontal axis. Did you plot it like this for a reason?
Oh sorry, I just plots it to see what happened in the trajectory sent by ROS. I have no a reason for put time on the vertical axis :)).
Then I would suggest to post plots where time is on the horizontal.
I have tried it lately but values of time is too long so they overlap each other (i want to keep it nsecond). So that, i think it will be better if my plots is kept like that. Many Thanks for your comment ^ ^
