panda_hand_eye_calibrate

基于easy_handeye开源项目,对Franka_panda进行手眼标定(Kinect v2);里面主要是修改了一些easy_handeye中的一些launch文件,实现手眼转换矩阵的计算与发布。

依赖

  1. 需要安装easy_handeye包;参看https://github.com/IFL-CAMP/easy_handeye;
  2. 安装我们修改的panda_moveit_config,以及panda_server

标定

  1. 自行安装好相机和标定板,标定板使用 ar_track_alvar生成的10cm*10cm的二维码标签,id为7;注意标定板完全处于相机视野范围,并且距离桌面一定距离,防止自动移动时与桌面出现碰撞

  2. 解锁panda机械臂,并启动Moveit

    cd ~/catkin_ws #cd where you put your "panda_client.sh"
    source panda_client.sh -r
    # ctrl+c
    roslaunch panda_moveit_config zzu_panda_move.launch
  3. 另一个命令窗口,打开相机

    cd ~/catkin_ws #cd where you put your "panda_client.sh"
    source panda_client.sh
    roslaunch kinect2_bridge kinect2_bridge.launch publish_tf:=true
  4. 打开窗口进行监视

    cd ~/catkin_ws #cd where you put your "panda_client.sh"
    source panda_client.sh 
    rosrun kinect2_viewer kinect2_viewer kinect2 sd cloud
  5. 另一个命令窗口,进行标定,按照提示进行标定

    cd ~/catkin_ws #cd where you put your "panda_client.sh"
    source panda_client.sh 
    roslaunch panda_hand_eye_calibrate panda_eob.launch

已标定&使用

  1. 发布手眼姿态矩阵

    cd ~/catkin_ws #cd where you put your "panda_client.sh"
    source panda_client.sh 
    roslaunch panda_hand_eye_calibrate publish_panda_eob.launch
  2. 解锁panda机械臂,并启动Moveit

    cd ~/catkin_ws #cd where you put your "panda_client.sh"
    source panda_client.sh -r
    # ctrl+c
    roslaunch panda_moveit_config zzu_panda_move.launch

TroubleShooting

如果tf出现问题,就先重新启动Moveit步骤;
