wit_ros

Wrapper for the wit.ai natural language API

Installation

    $ sudo pip install wit
    $ cd catkin_ws/src
    $ git clone https://github.com/LoyVanBeek/wit_ros.git
    $ cd catkin_ws
    $ catkin_make

Be sure to create a file api.yaml in a param directory, like this:

    $ roscd wit_ros/param
    $ vim api.yaml #Use any editor to edit the API key
      api_key: V.....Z #Get your API key/access token from https://console.wit.ai/#/settings

After rosmake-ing this package, you can run it with

   $ roslaunch wit_ros start.launch

Then, run

    $ rosservice call /wit/interpret "sentence: 'Clean up the table in the living room'"

Which outputs:

msg_body: {u'outcomes': [{u'entities': {u'item': [{u'type': u'value', u'value': u'the table'}], u'location': [{u'suggested': True, u'type': u'value', u'value': u'living room'}]}, u'confidence': 0.998, u'intent': u'cleanup', u'_text': u'Clean up the table in the living room'}], u'msg_id': u'fcdd89ed-2984-464e-89e6-fce78060e54e', u'_text': u'Clean up the table in the living room'}
msg_id: fcdd89ed-2984-464e-89e6-fce78060e54e
outcome: 
  confidence: 0.998000025749
  intent: cleanup
  entities: 
    - 
      name: item
      type: value
      value: the table
      unit: ''

    - 
      name: location
      type: value
      value: living room
      unit: ''
      suggested: True

Or, run

    $ rosservice call /wit/listen_interpret

And just say your command!
