+# Teleop
+## Samples
+
+rosbridge listener: a node that subscribes to the "teleop" topic and prints all received messages to the console
+rosbridge publisher: a node that publishes a VRHandPose message to the "teleop" topic on a timer
+
+running humanoid-server will allow you to listen to, and publish over the "teleop" topic over websocket. You should be able to see messages published from humanoid-server on the ros side, and messages published from ros in humanoid-server.
+
+To run rosbridge listener:
+```
+ros2 run rosbridge_listener rosbridge_listener_node
+```
+
+To run rosbridge publisher:
+
+```
+ros2 run rosbridge_publisher rosbridge_publisher_node
+```
+
+## Running Rosbridge Server
+Rosbridge server will relay ros topics to humanoid-server. To run, use:
+```
+ros2 launch rosbridge_server rosbridge_websocket_launch.xml
+```
+
+## Full Setup for Testing VR -> ROS
+These commands were run with the autonomy/samples folder deleted, since some packages may overlap
+
+```bash
+
+# In humanoid repo:
+cd autonomy/teleop
+colcon build
+source install/setup.bash
+ros2 run rosbridge_listener rosbridge_listener_node
+
+# Then, in another terminal:
+cd autonomy
+source install/setup.bash
+ros2 launch rosbridge_server rosbridge_websocket_launch.xml
+
+# In humanoid-server repo:
+npm run dev
+```
+
+Then, connect to ws://localhost:3000 (default websocket url) and send an example hand pose message:
+```
+[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]
+```
+The message should appear in the terminal where you ran the rosbridge listener node
