Hello,

Is it possible to run a Universal Robot Urp file or Script file from ROS PC to control a UR robot in the simulator(rviz/Gazebo)? The use case is that: I have a program (URP file) that is used to move the robot without collision to the home position during a process. And now I want it to test this program for its functionality from anywhere in the work space. My idea is to make a ros visualization in rviz or gazebo and to initially move the robot to a random point in the work space and call the safety program from ros pc to detect any collision in the simulator. I can record all those points where a collision is detected and I can later correct the program if I want to prevent the collision in future.

Is it possible to do this. Please let me know your suggestions. Thanks.

Ok. Got it. Thanks :)

Thanks a lot for your answer. I guess your second option is doable easily. But i didn't understood what you meant by " b

Running a Universal Robot Urp or Script file from ROS PC Hello, Is it possible to run a Universal Robot Urp file or Scr

My design which i got from another source is in stl format and contains lot of unwanted objects like holes,screws,extrusions etc..in it.So i need to delete all those unwanted parts from my mesh file.(to improve processing power) So is it ok to use a solidworks file (i am planning to design it from scratch) or modify the stl file using any stl editor?

Hello I want to create a package for controlling the turtlebot arm with the xbox controller i have.Please help me with some ideas to implement it..

Details Closed

thank u so much for the help.it worked

in rviz.... i just commented out joint_state_publisher node in rviz launch file

My problem is this..I need to connect a turtlebot arm to the turtlebot . So i called the xacro file of the turtlebot arm from the turtlebot_library.urdf.xacro. So when i launch the turtlebot in rviz the turtlebot with arm comes with the joint_state_publisher python tab where i can control the the joint states of the arm joints and the bot wheels.

But when i run the arm controller the arm is vibrating back and forth between the position given by the joint_state_publisher and the arm controller. So i searched how to stop this..then i found in a website to comment out joint_state_publisher if arm controler is used.But when i comment out it, a error is showing in turtlebot tires (when launched in rviz) saying there is no transformation between left and right wheells with base_foot print.... (but the vibration of the arm stops and the controller works fine)

So is there any way to stop publishing the joint states of the arm instead of commenting out the joint_state_publisher of turtlebot or will the error will be resolved if i send some position messages to the turtlebot wheels?

Please help...thanks in advance

When i comment it out i am getting an error showing there is no transformation between basefoot print and the left and right wheels. How to remove this error? Will the error go if i give some joint velocities for the turtle bot wheels?

I cant find the launch file to comment out the joint_state_publisher as mentioned in this link http://forums.trossenrobotics.com/sho... If i didnt comment out the joint_state_publisher,its creating conflct with the arbotix controller and is causing the arm to shake back and forth between two positions(given by arm controller and the joint_state_publisher).

Please help....

where is turtlebot_node.py file located.I searched my whole system,but i couldn't find it...pls help

URDF is easy to understand but difficult to modify in future...if u have a big urdf file go for xacro

I have two packages joint together using xacro (turtlebot and arm package). The arm controller package is publishing a joint state and the turtle bot package is publishing its joint state. So now the arm is vibrating because of two joint states published by the bot and the arm controller. So how can i delete one of the arm joint publisher or joint them both together? Please help.

Hello, I connected the turtlebot and pincherx arm.If anyone have a problem in connecting them both you can contact me.

I tried to link the phantomx pincher arm and turtlebot in rviz.But when i load the rviz its showing turtlebot and tf of both arm and turtlebot.But its not showing the arm .Please help me to solve this issue.

I tried evrything as given in the website http://wiki.ros.org/turtlebot_arm/Tut... But when i run the turtlebot in rviz,Its showing this error

while processing /home/asd/catkin_ws/src/turtlebot-indigo/turtlebot_bringup/launch/includes/robot.launch.xml: while processing /home/asd/catkin_ws/src/turtlebot-indigo/turtlebot_bringup/launch/includes/description.launch.xml: Invalid tag: Cannot load command parameter [robot_description]: command [/opt/ros/indigo/share/xacro/xacro.py '/home/asd/catkin_ws/src/turtlebot-indigo/turtlebot_description/robots/kobuki_hexagons_asus_xtion_pro.urdf.xacro'] returned with code [1].
