JUNCHAO Posted June 7, 2018 Share Posted June 7, 2018 Hello Intera team, When I finished all the install process by following the Intera SDK Gazebo tutorial, I tried to launch the gazebo simulator and run the example: $ ./intera.sh sim $ roslaunch sawyer_sim_examples sawyer_pick_and_place_demo.launch but through the terminal, I saw some errors and warnings. It shows many example codes have errors. and a Warning shows " Converting a deprecated SDF source[data-string]." Can anyone help me diagnose it or provide any advice? So appreciate!

Ian McMahon Posted June 8, 2018 Share Posted June 8, 2018 Hi Junchao, The error you've reported is just a Warning caused by gazebo_ros_control_plugins for the camera system, and will not cause the launch to fail. The real Traceback seems to be cut off in your screen shots, so that will be hard for us to debug. Can you please include your full error output? Thank you, ~ Ian Link to comment Share on other sites More sharing options...

Ian McMahon Posted June 11, 2018 Share Posted June 11, 2018 It appears the following error is the core of your issue, stating that Gazebo is crashing: Quote [gazebo-1] process has died [pid 2361, exit code 255, cmd /opt/ros/kinetic/lib/gazebo_ros/gzserver -e ode /home/robotics/ros_ws/src/sawyer_simulator/sawyer_gazebo/worlds/sawyer.world __name:=gazebo __log:=/home/robotics/.ros/log/a7089d10-69e5-11e8-955e-b9d69a7f7dd1/gazebo-1.log]. log file: /home/robotics/.ros/log/a7089d10-69e5-11e8-955e-b9d69a7f7dd1/gazebo-1*.log Gazebo is dying on launch. A few thoughts to debug the issue: 1) can you launch gazebo by itself? $ source /opt/ros/kinetic/setup.bash && gazebo 2) is your system up to date? $ sudo apt-get install dist-upgrade 3) Are you using a dedicated NVidia graphics card with the proprietary drivers installed? Ubuntu Search -> Additional Drivers -> select radial for Using NVIDIA binary driver - version 3xx.x from nvidia (proprietary) see the image attached for details: I hope this helps! ~ Ian Link to comment Share on other sites More sharing options...
JUNCHAO Posted June 12, 2018 Author Share Posted June 12, 2018 Hello Ian, -Gazebo could be launched by itself and seems all fine (See the attachment). -When I was trying to check the system updates, it shows the "dist-upgrade" package cannot be found. -For NVIDIA, the additional driver, I wonder why this laptop doesn't have any additional driver with Ubuntu 16.04. (See the attachment). Should I just download and install this NVIDIA binary driver with version 396.xx.xx? Thanks, Junchao Li Link to comment Share on other sites More sharing options...
Ian McMahon Posted June 13, 2018 Share Posted June 13, 2018 Do you know if your computer has a graphics card? I have a feeling a lack of (or underpowered) graphics card is the root of the issue.

JUNCHAO Posted June 13, 2018 Author Share Posted June 13, 2018 Hello Ian, My Graphic card appears as "Intel® HD Graphics 520 (Skylake GT2) ". Junchao Li Link to comment Share on other sites More sharing options...
Ian McMahon Posted June 13, 2018 Share Posted June 13, 2018 Hi Junchao, "Intel HD Graphics 520 (Skylake GT2)" means that your computer does not in fact have a graphics card, and is instead relying on integrated graphics. This will likely not work with the relatively complex simulation and models for Sawyer, which explains your errors in execution. Please see the minimum requirements section of Gazebo for details:http://gazebosim.org/tutorials?tut=guided_b1&cat=#Systemrequirements I would recommend using a system with a dedicated graphics card, preferably an NVidia card and use the proprietary NVidia drivers for it. I hope this helps! ~ Ian Link to comment Share on other sites More sharing options...
JUNCHAO Posted June 13, 2018 Author Share Posted June 13, 2018 Hello Ian, Thanks for the advice! It looks like a hardware issue. Since I am using the university provided laptop, so you mean I have to change a higher level laptop or computer in order to run it? Thanks, Junchao Li Link to comment Share on other sites More sharing options...
Ian McMahon Posted June 13, 2018 Share Posted June 13, 2018 Hi Junchao, That is correct. While your laptop will work for controlling the real Sawyer hardware, it does not meet the minimum specs for data Visualization or Simulation of Sawyer. Please request hardware with a dedicated graphics card to simulate Sawyer. Best, ~ Ian Link to comment Share on other sites More sharing options...
JUNCHAO Posted June 18, 2018 Author Share Posted June 18, 2018 Hello Ian, Just wanna be clear. What is the minimum requirement as a dedicated NVidia graphic card? Thanks, Junchao Li Link to comment Share on other sites More sharing options...
Ian McMahon Posted June 18, 2018 Share Posted June 18, 2018 Hi Junchao, I am not 100% certain on the minimum required NVidia graphics card required, as neither we nor the Open Robotics Gazebo team have exhaustively tested NVidia's line of cards. I can tell you that my 2015 laptop containing an NVidia Quadro M1000M mobile graphics card will run sawyer_gazebo at the highest 1.0 realtime simulation factor, with the proper driver installed. You might be able to get away with an older / less powerful card, but I cannot guarantee it. I hope this helps. ~ Ian Link to comment Share on other sites More sharing options...
JUNCHAO Posted July 17, 2018 Author Share Posted July 17, 2018 Hello, I just got a new laptop with NV117 graphic card and i7 CPU, which should be enough to run the Gazebo. Since Gazebo is a simulator, it should be able to run without connecting to the sawyer robot. When I tried to run Gazebo in the shell of intera.sh sim, it showed as below. 169.254.14.184 is the ip address generated by "avahi-autoipd". I used this ip successfully operated robot through the terminal and launched the MoveIt. Does this mean I have to connect to the robot in order to run the Gazebo simulation? Please provide advise. Thanks! Junchao Li Link to comment Share on other sites More sharing options...
Ian McMahon Posted July 17, 2018 Share Posted July 17, 2018 Hi Junchao, The laptop and graphics card should be sufficient to run Sawyer in Gazebo, provided you've installed the correct driver as I outlined above. The error you are describing in your screenshot is a networking error. The ros server should have a loopback address on your computer like 127.0.0.1 or 127.0.1.1 in normal configurations. What is the contents of your /etc/hosts file? For instance, mine is the following: Quote 127.0.0.1 localhost 127.0.1.1 rhino rhino.local where "rhino" is my workstation's hostname. Then you can initialize your intera.sh environment with the following: $ ./intera.sh sim To get the simulated environment variables. I hope this helps! ~ Ian Link to comment Share on other sites More sharing options...
JUNCHAO Posted July 18, 2018 Author Share Posted July 18, 2018 Hi Ian, Did you mean the workstation needs a loop network, so it can talks to itself? Do I need to replace the ip in "intera.sh" file by my computer's ip (like 127.0.0.1)? Thanks, Junchao Li Link to comment Share on other sites More sharing options...
Ian McMahon Posted July 18, 2018 Share Posted July 18, 2018 Yes the workstation does need a loopback network, but you do not need to add the loopback IP to the intera.sh file. That is done automatically if you invoke intera.sh with the "sim" argument. ~ Ian Link to comment Share on other sites More sharing options...
