Ur10e Robot model parameter not found!

ROS
1

hi all. im using ros2 foxy on ubuntu 20.04.

im tring to use the ur10e arm with moveit as explind in : https://github.com/UniversalRobots/Un….

first i launch the controllers and the ur_moveit.

ros2 launch ur_bringup ur_control.launch.py ur_type:=ur10e robot_ip:=yyy.yyy.yyy.yyy use_fake_hardware:=true launch_rviz:=false

ros2 launch ur_bringup ur_moveit.launch.py ur_type:=ur10e robot_ip:="xxx.xxx" use_fake_hardware:=true launch_rviz:=true

inside the rviz i can use MotionPlaninng intrface and its working parfectly. if i want to use the MoveGroupInterface and control the arm frue code i get the erorr:

 [FATAL] [1662929960.551830751] [move_group_interface]: Unable to construct robot model. Please make sure all needed information is on the parameter server.
terminate called after throwing an instance of 'std::runtime_error'
  what():  Unable to construct robot model. Please make sure all needed information is on the parameter server.

i run my node from ros2 run and not launch file.

my code:

#include <moveit/move_group_interface/move_group_interface.h>
#include <moveit/planning_scene_interface/planning_scene_interface.h>
#include <moveit_msgs/msg/collision_object.hpp>

    int main(int argc, char** argv) {
    rclcpp::init(argc, argv);
    rclcpp::NodeOptions node_options;
    node_options.automatically_declare_parameters_from_overrides(true);
    auto move_group_node = rclcpp::Node::make_shared("tr_plnner", node_options);
    rclcpp::executors::SingleThreadedExecutor executor;
    executor.add_node(move_group_node);
    std::thread([&executor]() { executor.spin(); }).detach();
    static const std::string PLANNING_GROUP = "ur_manipulator";
    moveit::planning_interface::MoveGroupInterface move_group(move_group_node, PLANNING_GROUP);
    moveit::planning_interface::PlanningSceneInterface planning_scene_interface;
    std::cout<<"0"<<std::endl;
    rclcpp::shutdown();
    return 0; }
