khi_robot

This repository provides ROS support for KHI robots.
ROS distribution Kinetic, Melodic, and Noetic are supported.

How to Launch

1. Launch Control Node

Start khi_robot_control as:

roslaunch khi_robot_bringup ***_bringup.launch ip:=***

If you only want to view robot(not control), specify the argument 'viewer' to use viewer mode:

roslaunch khi_robot_bringup ***_bringup.launch ip:=*** viewer:=true

If you have no real robot, specify the argument 'simulation' to use loopback mode:

roslaunch khi_robot_bringup ***_bringup.launch simulation:=true

If you want to use gazebo simulation:

roslaunch ***_gazebo ***_world.launch

2. Launch MoveIt! Node

Start a MoveIt! script as:

roslaunch ***_moveit_config moveit_planning_execution.launch

Now you can see the rviz screen of MoveIt! and interact the robot with the GUI.

Notes

About this software

This software is experimental code. There are known issues and missing functionality.
The APIs are completely unstable and likely to change. Use in production systems is not recommended.

About Coordinate

KHI coordinate and ROS cordinate are different.

Origin of KHI coordinate is Robot Link1 origin.

Origin of ROS coordinate is World origin.

About controllers

khi_robot_control uses position_controllers/JointPositionController as default, and it can also use position_controllers/JointGroupPositionController.

position_controllers/JointPositionController : ***_arm_controller (e.g.)rs007n_arm_controller
position_controllers/JointGroupPositionController : ***_joint_group_controller (e.g.)rs007n_joint_group_controller

To check available controllers, you can use service controller_manager/list_controllers.
To switch controllers, you can use service controller_manager/switch_controller.

(e.g.)

$ rosservice call /controller_manager/list_controllers
controller: 
  - 
    name: "rs007n_joint_group_controller"
    state: "stopped"
    type: "position_controllers/JointGroupPositionController"
    claimed_resources: 
      - 
        hardware_interface: "hardware_interface::PositionJointInterface"
        resources: [joint1, joint2, joint3, joint4, joint5, joint6]
  - 
    name: "joint_state_controller"
    state: "running"
    type: "joint_state_controller/JointStateController"
    claimed_resources: 
      - 
        hardware_interface: "hardware_interface::JointStateInterface"
        resources: []
  - 
    name: "rs007n_arm_controller"
    state: "running"
    type: "position_controllers/JointTrajectoryController"
    claimed_resources: 
      - 
        hardware_interface: "hardware_interface::PositionJointInterface"
        resources: [joint1, joint2, joint3, joint4, joint5, joint6]

$ rosservice call /controller_manager/switch_controller "start_controllers:
- 'rs007n_joint_group_controller'
stop_controllers:
- 'rs007n_arm_controller'
strictness: 2" 
ok: True
