Chat with Lucy!

This recipe is based on IBM TJBot and uses the Watson Assistant and other Watson services to turn Lucy into a chatting robot.

Some possible things to tell her:

• "Lucy how are you?" - To get to know about her feelings.
• "Hello Lucy" - Lucy will say hello and waves her arm.
• "Lucy turn the light to red" - Switch the LED to the given color.
• "Lucy start disco party" - Rotate through all LED colors.
• "What time is it, Lucy?" - Lucy tells you the time.
• "Lucy what is this?" - Lucy takes a photo and tries to guess what she sees.
• "Lucy go to bed" - Ends the conversation

This recipe requires a TJBot with a microphone, a speaker, a LED, a servo arm and a camera.

First, make sure you have configured your Raspberry Pi for TJBot by following the bootstrap instructions.

To use the LED and Audio in paralled I use an external USB sound card.

To get this up and running Audio must be blacklisted, but not all modules!

After bootstrap script has been run enter

$ sudo vi /etc/modprobe.d/tjbot-blacklist-snd.conf

and delete the last line:

$ blacklist snd

Save the changes and restart the system.

Next, go to the lucy folder and install the dependencies.

$ cd lucy
$ npm install

Import the workspace-lucy.json file into the Watson Assistant service and note the workspace ID.

Create instances of all the required Watson services and note the authentication credentials.

Make a copy the default configuration file and update it with the Watson service credentials and the conversation workspace ID.

$ cp config.default.js config.js
$ nano config.js
<enter your service credentials and the conversation workspace ID in the specified places>

sudo node lucy.js

Note the sudo command. Root user access is required to run TJBot recipes.
