Lucy Conversation

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

Hardware

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

Build and Run

Bootstrap

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

Using Audio and the LED together

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.

Dependencies and configuration

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>

Run!

sudo node lucy.js

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