2022-06-08 05:49:41 -0500 marked best answer Does ompl generate path or trajectory?

Hi,

Does ompl generate path or trajectory? If it generate trajectory, where it creates time, velocity and acceleration profile for a path?

Thanks for any help in advance!

Hi,

I installed ROS onto Gumstix Overo and roscore command works before. But after I tried to download some ROS packages (though I didn't succeed), I found roscore does't work anymore.

This is the error message:

2020-09-09 15:19:50 -0500 marked best answer opencv undefined reference problem

I am trying to build learning_image_transport from image_transport tutorial on Gumstix Overo which has ros groovy running on linaro.

However, one of dependencies of learning_image_transport -- opencv2 cannot be resolved in system dependency. So I cannot use rosdep to install opencv2.

Then I went to http://opencv.org/downloads.html and downloaded version 2.4.3 and followed instruction to install OpenCV.

Then I copy opencv and opencv2 from usr/local/include to /ros_core_ws/install/include so that ROS can find all the header file of OpenCV(such as highgui.h).

However, when I make learning_image_transport, I got the following error:

2019-10-15 02:13:14 -0500 marked best answer Can rosbag record and playback action goal?

Hi,

I am wondering if rosbag is able to record a action goal? Right now, I use moveit to generate a trajectory for pr2 left arm. And I want to record the trajectory and use it again later.

I tried to use rosbag to record the message in topic 

/l_arm_controller/follow_joint_trajectory/goal

and tried to playback the message. I am able to see the playback message using "rostopic echo". However, pr2's left arm didn't move. I guess maybe pr2's left arm controller will only work once it receive a action goal.

Is there anyway to record a action goal?

Following is all topics related to left arm controller.

/l_arm_controller/command
/l_arm_controller/follow_joint_trajectory/cancel
/l_arm_controller/follow_joint_trajectory/feedback
/l_arm_controller/follow_joint_trajectory/goal

2017-12-01 07:01:06 -0500 marked best answer Questions about Moveit collision detection

Hi everyone,

I am doing research about safety issue about human and robot cooperation. I am really interested in using collision detection functionality provided by moveit. As far as I know, I can get the distance between world object and any part of pr2 link through moveit API of collision detection. I am wondering if it is possible to get the coordinates information about the point on pr2 link which is closest to the world object? And is it possible to get the joint vector (standard vector on z-axis of a joint) information?

Thanks for any help in advance!

update1:

For FCL distance check called in moveit, can I simply create a new fcl::DistanceRequest object with the public attribute "enable_nearest_points" set to true and pass the fcl::DistanceRequest object to "double d = fcl::distance(o1, o2, fcl::DistanceRequest(), dist_result);" ? If I do so, can I get nearest points between o1 and o2 from dist_result?

update2:

I modified the code in FCL distance check in following way:

fcl::DistanceResult dist_result;
dist_result.update(cdata->res_->distance, NULL, NULL, fcl::DistanceResult::NONE, fcl::DistanceResult::NONE); // can be faster
double d = fcl::distance(o1, o2, fcl::DistanceRequest(true), dist_result);
printf("\n print nearest point 1 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! \n  %f %f %f  \n",dist_result.nearest_points[0].data.vs[0], dist_result.nearest_points[0].data.vs[1], dist_result.nearest_points[0].data.vs[2]);
printf("\n print nearest point 2 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! \n  %f %f %f  \n",dist_result.nearest_points[1].data.vs[0], dist_result.nearest_points[1].data.vs[1], dist_result.nearest_points[1].data.vs[2]);

But I don't know why I got (0,0,0) for each nearest point.

2017-10-03 06:55:56 -0500 marked best answer A subscriber error

Hi everyone,

I tried to establish a subscriber in move_action_capability in Moveit!

I established the subscriber within method "move_group::MoveGroupMoveAction::executeMoveCallback_PlanOnly" and following is my code to establish the subscriber:

ros::NodeHandle handle;
ros::Subscriber sub = handle.subscribe("r_arm_controller/state", 1000, controllerStateCB);

This is my callback signature:

void controllerStateCB(const pr2_controllers_msgs::JointTrajectoryControllerState::ConstPtr& msg)
{
    for (int joint_index = 0; joint_index < 7; joint_index++)
    {
        current_joint_position[joint_index]=msg->actual.positions[joint_index];
        current_joint_velocity[joint_index]=msg->actual.velocities[joint_index];
    }
}

However, when I compile, I got the following error:

2016-07-21 04:14:59 -0500 marked best answer unable to get Point Grey USB camera work in ubuntu

Hello,

I have problem in using POINT GREY FIREFLY MV FMVU-13S2C digital camera to work on Ubuntu 11.04.

This is the version of ubuntu.

adrian@ubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 11.04
Release:    11.04
Codename:   natty

As far as I know, POINT GREY FIREFLY MV FMVU-13S2C uses IEEE1394 interface to transfer data with computer. So I downloaded the Coriander – the linux GUI for IEEE1394/Firewire cameras.

However, when I plugged in the camera and launched the coriander, this error appears:

Warning: could not find a Digital Camera on the bus. Please check that: -the cables are properly set -the devices on the bus are properly powered -your camera is compliant with the Digital Camera specs (see http://www.1394ta.org).

Then I run the command “lsusb”:

adrian@ubuntu:~$ lsusb
Bus 003 Device 002: ID 1e10:2002 Point Grey Research, Inc. 
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Apparently, the first output is the camera.

Then I guess maybe I need to configure udev to work with camera. So I run “sudo gedit /etc/udev/rules.d/10-pointgrey.rules” and type in the following text.

BUS=="usb", SYSFS{idVendor}=="1e10", SYSFS{idProduct}=="2002", GROUP="plugdev"

Then I restart the udev by “sudo restart udev” and restart coriander again. But the same error still appears.

Then I opened the official website of the POINT GREY and downloaded the FlyCapture2 software. Surprisingly, This software is able to recognize the camera. Why coriander cannot recognize camera? camera1394 ros node also cannot recognize camera.

Can any help me to solve this problem? Thanks in advance!

Everything works before I add the c++ source file into the source folder of the catkin package. After I add the c++ source file, configuration step works fine. But next when I run "make" to build the package, this kind of error appears. It seems it cannot find ROS library.

2015-11-16 01:36:02 -0500 marked best answer ROS unable to find opencv libraries

I am trying to build image_view from source on Gumstix Overo which has ros groovy running on linaro.

However, one of dependencies of image_view -- opencv2 cannot be resolved in system dependency. So I cannot use rosdep to install opencv2.

Then I went to http://opencv.org/downloads.html and downloaded version 2.4.3 and followed instruction to install OpenCV.

However, when I make image_view, I got the following error.

2015-11-16 01:33:28 -0500 marked best answer Does camera1394 support UDP transport layer?

I am trying to stream video from my gumstix Overo to my laptop with camera1394 package. With default TCP layer, I found there are 5 to 10 seconds delay and the frame rate is just about 1 frame/sec (which is not what I set 15 frames/sec). I know I need to compress image and I will do some research on that later.

Right now, I really want to change the data transport layer from TCP to UDP because UDP is batter for tele-operation. I know that I can change the transport layer by transport hint in subscriber node. So I did that in my image_view source code "image_nodelet.cpp".

At line 118, I changed: 

image_transport::TransportHints hints(transport, ros::TransportHints(), getPrivateNodeHandle());

to

image_transport::TransportHints hints(transport, ros::TransportHints().udp(), getPrivateNodeHandle());

And rosmake it again. Then I run the image_view to receive video. However I found it still utilize TCP transport layer instead of UDP. Does camera1394 support UDP transport layer?

My laptop have Ubuntu 12.04 running as a virtual machine and bridged the host network. I inspect the transport layer by wireshark in windows(host). I also doubt that if I make the right image_view package I edited because I know there is another one in /opt/ros/groovy/stacks. But I my ROS_PAKCKAGE_PATH is 

/home/adrian/catkin_ws/src:/opt/ros/groovy/share:/opt/ros/groovy/stacks

So I think rosmake should make the source image_view in my workspace.

Thanks and have a good day!
2015-10-14 16:25:27 -0500 marked best answer cannot install ros packages by command line

Hi,

I had the ROS groovy run on Gumstix Overo but I have trouble in installing ros packages with command line.

I want to install camera1394 so I type in sudo apt-get install ros-groovy-camera1394, however following error appears:

root@linaro-alip:~# sudo apt-get install ros-groovy-camera1394
Reading package lists... Done

E: Unable to locate package ros-groovy-camera1394

Then I try to update the package list, and this is output of sudo apt-get update:
