2019-04-08 01:10:37 -0500 marked best answer No home point in Moveit Cartesian Plan Plugin in

Hello, I have installed the Moveit Cartesian Plan Plugin in my rviz , when the "Move to Home" button is clicked, the robot move to the default origin pose i cannot define. So could you tell me how to configure the plugin or change the code of plugin to specify the "Home" point?

2019-04-08 01:06:38 -0500 marked best answer How to avoid the axis jumping when the orientation is constrainted

Hi

Now the end-effector's orientation constraints is implemented in my offline simulation in Moveit. It can be seen that the orientation of end-effector is keeping horizontal to the ground. But during the motion, several axis of UR-10 jumps anyway. So do you guys know how to avoid the unexpected pose?

video!!!!!!!!!!

On the other hand, i am using Trac IK to UR-10 and the solve_type is inevitably set as 'speed', which has been changed as 'distance' in kinematics.yaml, when running the c++ code. Will this setting affects the axis jumping?

2018-07-20 03:51:12 -0500 marked best answer How to add a tool model onto the robot model which can be generated in the moveit

Hey guys, I have downloaded the UR10 robot description(including the urdf and other components) in the ROS without a tool on the end effector. Now i have a mechanical mechanism which has been exported as a URDF in Solidworks. The problem is how can i add the mechanical mechanism as a tool on the robot end effector and open the entire model in the RVIZ? Do you have any tutorial about it?

2018-06-26 03:54:16 -0500 marked best answer Some errors occurred when package was compiling.(LINK ERROR)

Hey guys, i just copy the codes , in the Chapter 10 of book,' Mastering ROS for Robotics Programming', to my ros. The cmakelists file is written as followed,


cmake_minimum_required(VERSION 2.8.3)
project(seven_dof_arm_test)
find_package(catkin REQUIRED COMPONENTS
  cmake_modules
  interactive_markers
  moveit_core
  moveit_ros_perception
  moveit_ros_planning_interface
  pluginlib**
  roscpp
  std_msgs
)
find_package(Boost REQUIRED COMPONENTS system)
catkin_package(
)
include_directories(
  ${catkin_INCLUDE_DIRS}
)
add_executable(test_random_node src/test_random.cpp)
add_dependencies(test_random_node seven_dof_arm_test_generate_messages_cpp)
target_link_libraries(test_random_node
   ${catkin_LIBRARIES}
 )
include_directories(
  ${catkin_INCLUDE_DIRS}
)

And the cpp file is shown as followed,

#include <moveit/move_group_interface/move_group.h>
int main(int argc, char **argv)
{
  ros::init(argc, argv, "move_group_interface_demo", ros::init_options::AnonymousName);
  // start a ROS spinning thread
  ros::AsyncSpinner spinner(1);
  spinner.start();
  // this connecs to a running instance of the move_group node
  move_group_interface::MoveGroup group("arm");
  // specify that our target will be a random one
  group.setRandomTarget();
  // plan the motion and then move the group to the sampled target 
  group.move();
  ros::waitForShutdown();
}

Now when the package is compiling, the error occured ,

Linking CXX executable /home/aicrobo/catkin_ws/devel/lib/seven_dof_arm_test/test_random_node
/opt/ros/indigo/lib/libmoveit_planning_scene_monitor.so: undefined reference to `ros::WallTimer::setPeriod(ros::WallDuration const&, bool)'

So do you have any idea about the problem? Thank you
