Reach Alpha 5 ROS 2 Driver 🦾

The Alpha 5 driver is a collection of ROS 2 packages designed to support ROS 2 integration with the Reach Alpha 5 manipulator.

Deprecation Notice

We have deprecated this repository in favor of our reach repository, which integrates additional features and support for the Reach Bravo 7 manipulator.

Main features

The main features of the Alpha 5 driver are:

• Integration of the Reach System Serial Protocol for hardware communication
• ros2_control integration for manipulator position, velocity, and joint trajectory control
• Simulation support using Gazebo Garden
• Visualization support using RViz2
• Integration with MoveIt2 for motion planning

Installation

The Alpha 5 driver is currently supported on Linux, and is available for the ROS distributions Humble and Rolling. To install the Alpha 5 driver, first clone this project to the src directory of your ROS workspace, replacing $ROS_DISTRO with the desired ROS distribution or main for Rolling:

git clone -b $ROS_DISTRO git@github.com:evan-palmer/alpha.git

After cloning the project, install the ROS dependencies using rosdep, again, replacing $ROS_DISTRO with the desired ROS distribution:

rosdep update && \
rosdep install -y --from-paths src --ignore-src --rosdistro $ROS_DISTRO

Quick start

A ROS 2 launch file has been provided to start the Alpha 5 driver. To launch the driver using default arguments, run

ros2 launch alpha_bringup alpha.launch.py

A full description of the launch arguments and their respective default values can be obtained by running the following command:

ros2 launch alpha_bringup alpha.launch.py --show-args
