Overview

Motion retargeting is the process of mapping motions between different kinematic structures. This stack implements a simple, yet effective motion retargeting method that is used in the context of a unilateral teleoperation system for transferring upper body motions from a human operator to a robot in an online fashion.

The operator's motion is captured using a Kinect device. In order to capture as much of the original motion's expressiveness as possible, we are making use of multiple end-effectors, which are currently the wrists, elbows, torso and head (caveat: the openni_tracker does not capture head/wrist orientation). Then, we adapt the captured motion to the robot's kinematic structure, which can differ significantly in terms of number of degrees of freedom and body proportions. Finally, an inverse kinematics computation produces a joint space reference for the robot to follow. This reference takes into account technological and geometric constraints like joint position and velocity limits, as well as self-collisions.

Installation

  Show EOL distros: 

  • ROS

    • ROS Electric full desktop:
      • sudo apt-get install ros-electric-desktop-full

    • Arm navigation stack:
      • sudo apt-get install ros-electric-arm-navigation

      • sudo apt-get install ros-electric-arm-navigation-experimental

    • OpenNI Kinect stack:
      • sudo apt-get install ros-electric-openni-kinect

  • reem_teleop

    • We need to get not only the source for this stack, but also the REEM model, and the packages to overlay. A rosinstall file is provided to automate this step. It can be found here.

    • The following is an example of a rosinstall invocation that downloads the code to ~/workspace and preserves the default ros electric setup:

      rosinstall ~/workspace /opt/ros/electric https://raw.github.com/pal-robotics/pal-ros-pkg/electric/motion_retargetting.rosinstall

  • ROS

    • ROS Electric full desktop:
      • sudo apt-get install ros-fuerte-desktop-full

    • Arm navigation stack:
      • sudo apt-get install ros-fuerte-arm-navigation

      • sudo apt-get install ros-fuerte-arm-navigation-experimental

    • OpenNI Kinect stack:
      • sudo apt-get install ros-fuerte-openni-kinect

  • reem_teleop

    • We need to get not only the source for this stack, but also the REEM model, and the packages to overlay. A rosinstall file is provided to automate this step. It can be found here.

    • The following is an example of a rosinstall invocation that downloads the code to ~/workspace and preserves the default ROS Fuerte setup:

      rosinstall ~/workspace /opt/ros/fuerte https://raw.github.com/pal-robotics/pal-ros-pkg/fuerte/motion_retargetting.rosinstall

Support for Groovy is on its way.
