JUNCHAO Posted June 12, 2018 Share Posted June 12, 2018 Hello Intera Team, I was trying to plan and execute the trajectory in Moveit, but it always fails whatever how to plan it. I know it seems to be similar to the few previous topics that other users posted, but I really tried all the methods I found in this forum and even on the whole Internet. Our university tech guys fixed the NTP issue for me, but it still fails. I don't know what to do right now. I have been suffering from this for few weeks too. I attach the whole launch code and the trajectory plan code here.

Ulysse Posted June 13, 2018 Share Posted June 13, 2018 Just to be sure the two are in sync, can you echo the `robot/joint_states` topic and look for the timestamp? When you compare it to your workstation computer's using the `date +%s` command, the two should not be off by more than a few seconds. For more precise results you could install the `clockdiff` command (package `iputils-clockdiff` on Ubuntu) and use it to check the clocks offset : `clockdiff -o <ip>.<of>.<your>.<sawyer>` Let me know Link to comment Share on other sites More sharing options...
JUNCHAO Posted June 13, 2018 Author Share Posted June 13, 2018 Hello Ulysse, Thanks for your reply! -When I used the command "date+%s", it shows a very big number. Does that mean they are still not sync yet? robotics@robotics-Latitude-E5470:~/ros_ws$ date +%s 1528927112 -I used "ntpdate -q <workstation_ip>" to test the synchronization, I think it shows it is good. ntpdate -q 169.254.221.25 server 169.254.221.25, stratum 3, offset -0.000020, delay 0.02570 13 Jun 16:57:29 ntpdate[20200]: adjust time server 169.254.221.25 offset -0.000020 sec -I used "rostopic echo /robot/joint_states" to grab the joint states, please see the attachment below. Thanks for the help! Please let me know what do you think. Junchao Li Link to comment Share on other sites More sharing options...
Ulysse Posted June 14, 2018 Share Posted June 14, 2018 Haha I think I did not explain myself very well. The `date +%s` command is to get the current clock value of your workstation at a given time. The number is big because it is the number of seconds elapsed since 1970 (we call it epoch). When Sawyer sends a joint_state message, it calls it under the hood and use it to fill the `header.stamp.secs` message (the `header.stamp.nsecs` message is filled with the result of command `date +%N` but we're not really interested in this one yet). For short, just run the following command and post the output: date +%s & rostopic echo -n 1 /robot/joint_states/header/stamp/secs To speed things up I also want you to execute the following command: clockdiff -o <ip>.<adress>.<of>.<sawyer> # Be careful: IP address of Sawyer, not NTP server!
