Arunava Nag Posted September 15, 2017 Share Posted September 15, 2017 Hello, I am having a Sawyer. My system is running ROS Kinetic in Ubuntu 16.04. I tried using the sh script, it ssh s myself inside how ever I cannot communicate with the ROS master. I tried using a virtual machine running ROS Indigo and Ubuntu 14.04. I still couldn't communicate to the ROS master. In all the cases i could ping the system from my workstation. Also in my SDK mode, it throws camera calibration error. I have attached a screenshot of that. Kindly help. Quote Link to comment Share on other sites More sharing options...
Arunava Nag Posted September 15, 2017 Author Share Posted September 15, 2017 Solved connection issue, however what about camera config failing. Quote Link to comment Share on other sites More sharing options...
Don Spear Posted September 15, 2017 Share Posted September 15, 2017 Hi Arunava, Can you please confirm the software version installed on your robot? If you are not running 5.1.2.4, I recommended downloading the updated files from the downloads section of the forum and updating your robot to the latest version.

Don Spear Posted September 15, 2017 Share Posted September 15, 2017 Hi Arunava, In addition, we will be contacting you off line in order to follow up on your issue as this is a potential hardware issue. If any other users see this message, please email support@rethinkrobotics.com with details including the serial number of your robot.

Arunava Nag Posted September 20, 2017 Author Share Posted September 20, 2017 Hi Don, Thanks for your response. First of all, I have been using the google group for Baxter since 2015 and this forum is quite new to me. I have clicked on the notify me, however, it did not send me any notification of your responses. Sorry for the delay. Please find attached the version I am running. The camera calibration issue is only visible in SDK mode and it's occasional, that is, I don't see it after every bootup. My distributor advised me to run the camera tests from FSM which I did and I got OK for both the results FYI. Quote Link to comment Share on other sites More sharing options...
Arunava Nag Posted September 20, 2017 Author Share Posted September 20, 2017 Also, Do we have examples for Sawyer in C++ especially with MoveIt? Quote Link to comment Share on other sites More sharing options...
Don Spear Posted September 20, 2017 Share Posted September 20, 2017 Hi Arunava, I will continue to follow up with you off line regarding the camera issue, this may be a hardware error. Regarding following the forum, unfortunately, you need to follow each individual topic if you want to see replies. When you are following the forum, you will be notified of new posts but in order to see replies, you need to follow the specific topic. Regarding the C++ question, I recommend creating a separate post. Best, Don Quote Link to comment Share on other sites More sharing options...

Enrico Mattei Posted May 25, 2018 Share Posted May 25, 2018 Sorry Arunava Nag, I have the same problem of connection with my Sawyer. In my Konsole appear the follow error message, after rostopic list command: ERROR: Unable to communicate with master! How did you solve the connecting problem?

rdoshi21 Posted November 10, 2022 Share Posted November 10, 2022 I'm currently running into a similar issue. I'm able to ping the robot, but when I run rostopic list, it hangs for a while before saying "ERROR: master node may not be running." similarly, when I try to enable the robot, it gives an error saying the master node is not running. in my intera script, the robot_hostname is set to <serialnumber.local> which I can ping, and your_hostname is set to the IP of my computer. any help would be really appreciated! 1 Quote Link to comment Share on other sites More sharing options...
