coffee_shop_ui

Provides a tablet user interface for ordering and confirming actions within the coffee shop task.

This package is maintained by:

• Paul Makles

Prerequisites

This package depends on the following ROS packages:

• catkin (buildtool)
• message_generation (build)
• message_runtime (exec)

This package currently requires a rosbridge WebSocket server to run on port 9090 on the same machine running this node.

Usage

Start a rosbridge server using:

roslaunch rosbridge_server rosbridge_websocket.launch

Build and run the coffee shop UI:

rosrun coffee_shop_ui build # don't need to run again except to update
rosrun coffee_shop_ui start

# .. or run a dev server:
rosrun coffee_shop_ui dev

You can now access the web server on $ROS_IP:3000.

You can now publish std_msgs/String to /tablet/screen with the string being one of:

• home

• order

  A coffee_shop_ui/Order message will be published to /tablet/order when the user confirms their order.

  The message contains a list of items in any order, items names are repeated for how many were ordered.

• done

  A std_msgs/Empty message will be published to /tablet/done when the user presses the button.
