Installation

Build from source

• Install ROS environments. Please see ROS Wiki.

• Download the packages for CRANE-X7 using git.

  cd ~/catkin_ws/src
  git clone https://github.com/rt-net/crane_x7_ros.git

• Install package dependencies.

  cd ~/catkin_ws/src

  rosdep install -r -y --from-paths --ignore-src crane_x7_ros

Setup Serial Connection

The crane_x7_control node communicates with CRANE-X7 via serial port over USB. Logged-in user should have read and write access to /dev/ttyUSB0.

Change permissions on /dev/ttyUSB0 with the following command:

sudo chmod 666 /dev/ttyUSB0

About CRANE-X7 packages

crane_x7_description

This package defines CRANE-X7 model data including links and joints. The MoveIt packages and Gazebo require this package.

crane_x7_control

This package controls CRANE-X7 using Dynamixel SDK C++ Library which can install by rosdep install command. Read and write permissions on /dev/ttyUSB0 are required for communication between the package and CRANE-X7.

The device name of serial port and parameters of Dynamixel servo motors are listed in config/crane_x7_control.yaml. If this package did not find the serial port, the package switches its control mode to Dummy Joint Mode from Normal Mode and republishes target joint values as servo angle values. This is useful for debugging of motion control without CRANE-X7 hardware.

At startup, this package moves the CRANE-X7 to Home Position in 5 seconds. At shutdown, this package decreases P gains of the servo motors to stop motion safely.

crane_x7_moveit_config

This package includes configuration files for MoveIt.

To launch the MoveIt demonstration with Rviz:

roslaunch crane_x7_moveit_config demo.launch

crane_x7_bringup

This package includes launch files for startup of CRANE-X7.

crane_x7_examples

This package includes example codes for CRANE-X7. Please refer to ./crane_x7_examples/README.md.

crane_x7_gazebo

This package includes Gazebo simulation environments for CRANE-X7.

To simulate CRANE-X7 on the table:

roslaunch crane_x7_gazebo crane_x7_with_table.launch
