The Open Robotics Middleware Framework (Open-RMF) enables interoperability among heterogeneous robot fleets while managing robot traffic that share resources such as space, building infrastructure systems (lifts, doors, etc) and other automation systems within the same facility. Open-RMF also handles task allocation and conflict resolution among its participants (de-conflicting traffic lanes and other resources). These capabilities are provided by various libraries in Open-RMF. For more details about Open RMF, refer to the comprehensive documentation provided here.
This repository contains demonstrations of the above mentioned capabilities of RMF. It serves as a starting point for working and integrating with Open-RMF.
These demos were built and tested on
Note: RMF is fully supported on ROS 2 Foxy as well
Instructions can be found here.
Answers to frequently asked questions can be found here.
A near-term roadmap of the Open-RMF project can be found in the user manual here.
Full web application of Open-RMF: rmf-web.
In order to interact with the default configuration of the web application, the server_uri launch parameter will need to be changed to ws://localhost:8000/_internal, for example,
ros2 launch rmf_demos_gz office.launch.xml server_uri:="ws://localhost:8000/_internal"By specifying server_uri, the fleetadapter will update rmf-web api-server with the latest task and robot states. User can then monitor on-going states and initiate rmf task with an interactive web dashboard.
- Hotel World
- Office World
- Airport Terminal World
- Clinic World
- Campus World
- Manufacturing & Logistics World
Note: When running the demos on Ubuntu 18.04 (not officially supported), you are required to explicitly supply gazebo_version launch argument. Eg: ros2 launch rmf_demos_gz_classic office.launch.xml gazebo_version:=9
To run the demos using Ignition instead of Gazebo, change the commands from
ros2 launch rmf_demos_gz_classic [...]toros2 launch rmf_demos_gz [...]
RMF Panel
Click this link: https://open-rmf.github.io/rmf-panel-js/
For a full-proof web application of Open-RMF, please refer to rmf-web.
The RMF panel is a web based dashboard for interacting with rmf_demos. It allows users to send task requests to RMF and monitor the status of robots and submitted tasks. For more details.
There are two main modes of submitting tasks to Open-RMF via the Panel:
- Submit a Task: Used to submit a single task.
- Submit a List of Tasks: Used to submit a batch of tasks. A
.jsonfile containing a list of tasks may be loaded via theChoose filebutton. Some example files are found inrmf_demos_panel/task_lists.
LATEST UPDATE: Display Task States
task_state_uptates are now published via websocket. To display task states on rmf-panel, specify server_uri:="ws://localhost:7878" during ros2 launch. Example:
ros2 launch rmf_demos_gz_classic office.launch.xml server_uri:="ws://localhost:7878"
This will let Open-RMF (websocket clients) to publish their states to port 7878. In this case, rmf-panel's api_simple_server is the websocket server.
This hotel world consists of a lobby and 2 guest levels. The hotel has two lifts, multiple doors and 3 robot fleets (4 robots). This demonstrates an integration of multiple fleets of robots with varying capabilities working together in a multi-level building.
To launch the world and the schedule visualizer,
source ~/rmf_ws/install/setup.bash
ros2 launch rmf_demos_gz_classic hotel.launch.xml
# Or, run with ignition simulator
ros2 launch rmf_demos_gz hotel.launch.xmlHere, we will showcase 2 types of Tasks: Loop and Clean
Open RMF Panel to submit clean or loop requests.
To submit a loop task, select Loop from the Select a request type dropdown list. Choose desired start and end locations and click submit. Similarly for Clean task, select Clean, then choose the desired cleaning zone from the dropdown list.

This demo world shows robot interaction on a much larger map, with a lot more lanes, destinations, robots and possible interactions between robots from different fleets, robots and infrastructure, as well as robots and users. In the illustrations below, from top to bottom we have how the world looks like in traffic_editor, the schedule visualizer in rviz, and the full simulation in gazebo,
In the airport world, we introduce a new task type to rmf: Clean. To launch the world:
source ~/rmf_ws/install/setup.bash
ros2 launch rmf_demos_gz_classic airport_terminal.launch.xmlOpen RMF Panel. Load the airport_terminal_tasks.json list and click submit to begin a collection of loop, delivery and cleaning tasks.
Or, submit loop, delivery or clean task via CLI:
ros2 run rmf_demos_tasks dispatch_patrol -p s07 n12 -n 3 --use_sim_time
ros2 run rmf_demos_tasks dispatch_delivery -p mopcart_pickup -ph mopcart_dispenser -d spill -dh mopcart_collector --use_sim_time
ros2 run rmf_demos_tasks dispatch_clean -cs zone_3 --use_sim_timeTo see crowd simulation in action, enable crowd sim by:
ros2 launch rmf_demos_gz_classic airport_terminal.launch.xml use_crowdsim:=1Non-autonomous vehicles can also be integrated with Open-RMF provided their positions can be localized in the world. This may be of value at facilities where space is shared by autonomous robots as well as manually operated vehicles such as forklifts or transporters. In this demo, we can introduce a vehicle (caddy) which can be driven around through keyboard/joystick teleop. In Open-RMF nomenclature, this vehicle is classified as a read_only type, ie, Open-RMF can only infer its position in the world but does not have control over its motion. Here, the goal is to have other controllable robots avoid this vehicle's path by replanning their routes if needed. The model is fitted with a plugin which generates a prediction of the vehicle's path based on its current heading. It is configured to occupy the same lanes as the tinyRobot robots. Here, a read_only_fleet_adapter submits the prediction from the plugin to the Open-RMF schedule.
In the airport terminal map, a Caddy is spawned in the far right corner and can be controlled with geometry_msgs/Twist messages published over the cmd_vel topic.
Run teleop_twist_keyboard to control the caddy with your keyboard:
# Default launch with gazebo
ros2 run teleop_twist_keyboard teleop_twist_keyboard
# if launched with the Ignition simulator
ros2 launch rmf_demos_gz airport_terminal_caddy.launch.xml
Tip: To speedup simulation on gazebo, user can run
gz physics -ps 0.01on a separate terminal after launching the world. Use with care!
This is a clinic world with two levels and two lifts for the robots. Two different robot fleets with different roles navigate across two levels by lifts. In the illustrations below, we have the view of level 1 in traffic_editor (top left), the schedule visualizer in rviz (right), and the full simulation in gazebo (bottom left).
To launch the world and the schedule visualizer,
source ~/rmf_ws/install/setup.bash
ros2 launch rmf_demos_gz_classic clinic.launch.xmlOpen RMF Panel. Load the clinic_tasks.json list and click submit to begin a collection of loop and delivery tasks.
Or, submit a task via CLI:

ros2 run rmf_demos_tasks dispatch_patrol -p L2_north_counter L1_right_nurse_center -n 5 --use_sim_timeRobots taking lift:
Multi-fleet demo:
This is a larger scale "Campus" World. In this world, there are multiple delivery robots that operate. The world is designed and traffic lanes are annotated at the planet scale, using GPS WGS84 coordinates. Each robot is also streaming its location in WGS84 coordinates, which are processed by its fleet adapter. This demo intends to show the potential of Open-RMF on a large scale map.
To launch the world and the schedule visualizer,
source ~/rmf_ws/install/setup.bash
ros2 launch rmf_demos_gz campus.launch.xml
ros2 run rmf_demos_tasks dispatch_patrol -p room_5 campus_4 -n 10 --use_sim_time
ros2 run rmf_demos_tasks dispatch_patrol -p campus_5 room_3 -n 10 --use_sim_time
ros2 run rmf_demos_tasks dispatch_patrol -p room_2 dead_end -n 10 --use_sim_timefleet_robotmanager_mqtt_bridge (see rmf_demos_bridges) can be used to publish robot locations, battery percentage and state to a /robot/status/ROBOT-ID websocket endpoint. An instance of RobotManager can be configured to subscribe to this server to receive json messages, which will in turn visualize the robots on RobotManager.
# Install the prerequisites
sudo apt install mosquitto mosquitto-clients
# Start the bridge
ros2 run rmf_demos_bridges fleet_robotmanager_mqtt_bridge -y 31500 -x 22000The json messages for the first robot can be echoed using the following example command,

Open-RMF can also manage fleets whose API or fleet managers only offer pause and resume commands to control their robots. Such fleets are classified as traffic_light. To integrate a traffic_light fleet, users are expected to implement a traffic_light fleet adapter based on this API. The rmf_demos repository contains demonstrations of traffic_light fleets in various scenarios. A simplistic mock_traffic_light adapter is used in these demonstrations.

In Open-RMF version 21.04 and above, tasks are awarded to robot fleets based on the outcome of a bidding process that is orchestrated by a Dispatcher node, rmf_dispatcher_node. When the Dispatcher receives a new task request from a UI, it sends out a rmf_task_msgs/BidNotice message to all the fleet adapters. If a fleet adapter is able to process that request, it submits a rmf_task_msgs/BidProposal message back to the Dispatcher with a cost to accommodate the task. An instance of rmf_task::agv::TaskPlanner is used by the fleet adapters to determine how best to accommodate the new request. The Dispatcher compares all the BidProposals received and then submits a rmf_task_msgs/DispatchRequest message with the fleet name of the robot that the bid is awarded to. There are a couple different ways the Dispatcher evaluates the proposals such as fastest to finish, lowest cost, etc which can be configured.
Battery recharging is tightly integrated with the new task planner. ChargeBattery tasks are optimally injected into a robot's schedule when the robot has insufficient charge to fulfill a series of tasks. Currently we assume each robot in the map has a dedicated charging location as annotated with the is_charger option in the traffic editor map.
