Software Architecture --------------------- .. image:: media/figures/mmp_software_architecture.webp :width: 100% :align: center :class: mbsrounded | .. important:: The diagram illustrates the ROS package structure and interaction. Please note that the ``mmp_startup`` interacts will all others ros packages depending on the set environment variables. This section will explain all the custom packages that we have written which are being used in this particular robot. mmp_arm ~~~~~~~~ .. image:: media/figures/arm2.webp :width: 80% :align: center :class: mbsrounded | This package facilitates control of the Universal Robots UR5e robotic arm and Robotiq gripper through a customizable launch file. The launch file includes arguments for robot connection, tool communication parameters, and controller configurations. It also supports headless mode, URScript automation, and hardware interface node safety. Additionally, the launch file incorporates XML for UR common functionalities, connecting to the robot, and managing joint states in the ROS environment. mmp_lidars ~~~~~~~~~~ This package manages front and back Hokuyo Lidars, and an Ouster Lidar Sensor, with a dedicated ``lidars.launch`` file. The launch file includes configurations for each lidar type, allowing customization of parameters like IP address, ports, and visualization. mmp_msgs ~~~~~~~~ This package consists of custom messages for ``PanTilt`` and ``SoftSwitchesStatus`` which are used wile controlling different components of the robot. mmp_startup ~~~~~~~~~~~ The :code:`mmp` package manages the robot startup files. Ridgeback needs ROS to be running at startup. Ridgeback driver needs to run at startup which communicates between the robot and its MCU which is on network address ``192.168.131.1``. .. warning:: Make sure none of your devices are having **192.168.131.1** as well as **192.168.131.2** ip address this will crash the node and the robot will not function properly. This package is dependent upon :roswiki:`robot_upstart` which converts roslaunch files to systemd service job in Ubuntu. This job runs at the startup of the robot. The one responsible for Ridgeback is :code:`mmp_startup`. The status of this service can be checked by: .. code-block:: bash sudo service mmp status To update this launch file at the robot startup, run: .. code-block:: bash rosrun mmp_startup startup_installer.py .. attention:: This command will remove the previous job and install a new one. .. note:: Do not edit the files manually to systemd setup files or launch files (it won't work), always run the above mentioned command to reflect the changes. This packages also includes UDEV rules for different devices on the robot. They are already set up but for a fresh installation they can be run by: .. code-block:: bash ./setup_udev_rules.sh The packages have some configuration files for the robot utilities. For example ``config/description.bash`` is responsible set up environment variables for URDF in order to include parts on the go. Similarly config/setup.bash is responsible for setting up environment variables for Ridgeback drivers. mmp_demo ~~~~~~~~ This package runs an example to demonstrate the working of all the robot component attached with the robot simultaneously. A special movement has been programed in this package that will allow you to see all the component workings. mmp_pan_and_tilt ~~~~~~~~~~~~~~~~ This package is responsible for two servo motors on which one of the camera is attached. mmp_ur_moveit_config ~~~~~~~~~~~~~~~~~~~~ This package is responsible for the moveit configuration for all the sensors and components that are attached to the robot. mmp_description ~~~~~~~~~~~~~~~ This is a ros package that contains the 3D models of the Ridgeback. Additionally, the seperate 3D models are stitched together into a single entity via the universal robot description format (URDF). It contains the models for auxiliary components such as lidars as well. Additions to the robot's 3D model can be made in the ``xacro/accessories.urdf.xacro``. To view the robot with simulated dummy drivers. .. code:: bash roslaunch mmp_viz view_model.launch If you want to add more accessories to the robot please make sure that you add those accessories to ``accessories.urdf.xacro`` file located in ``mmp_description/xacro/`` so that the new accessories can be stitchedwith the old ones. mmp_lift ~~~~~~~~ This package is responsible for lift control. This package uses the rope encoder to provide ``joint_state`` of the lift hub for transforms between the different links.The lift itself communicates via an Arduino nano. mmp_realsense_cameras ~~~~~~~~~~~~~~~~~~~~~ This package is responsible for two realsense cameras(D455 & D405) control. .. note:: The package for Intel Realsense D405 has been ported from ROS2 to ROS1 and is custom, the default package will not work with mmp. Quick-Start ------------ Powering on the Ridgeback ~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. image:: media/figures/power.webp :width: 50% :align: center :class: mbsrounded | Confirm that the emergency buttons on all four corners are released. #.
