ROS2 Lint

telegram_ros2

Bridge the Telegram chat service to ROS2. Send messages, images, locations to and from ROS2

Useage

mkdir -p ~/dev_ws/src
cd ~/dev_ws/src
git clone https://github.com/LoyVanBeek/instant_messaging_interfaces.git
git clone https://github.com/LoyVanBeek/telegram_ros2.git

Get a Telegram API token via https://core.telegram.org/bots#6-botfather The token can be put in the config/example_param.launch:

$EDITOR config/example_param.launch

and save your token instead of the dummy example token (nope, the example one is not valid, you really need your own)

cd ~/dev_ws  # or cd .., whatever floats your goat. 
colcon build  # --symlink-install # TIL this is possible, for those wanting to hack on this
ros2 launch telegram_ros2 telegram_bridge.launch.py

Now, chat with your bot via Telegram. It'll report you need to first send a /start command (ince this bot can currently only talk to 1 person at a time) So, enter /start and start chatting.

Topics

  • Receiving messages from Telegram: ros2 topic echo /message_to_ros

  • Receiving images from Telegram: ros2 topic echo /image_to_ros or rather look at images with rqt

  • Receiving location from Telegram: ros2 topic echo /location_to_ros

  • Sending a message to Telegram: ros2 topic pub --once /message_from_ros std_msgs/msg/String data:\ \'Hello\'\

  • Sending a location to Telegram: ros2 topic pub --once /location_from_ros sensor_msgs/msg/NavSatFix or also use rqt

  • Images are sent to Telegram via publishing them to /image_from_ros, so you can remap your camera feed for example.
