One of the big things i have missed since we switched from LEAF to ROS is a voice and being able to talk with the robot. The LEAF program had only a few lines so it became boring very quickly and guests found it hard to strike up a conversation. I found a Python AIML Interpreter hacked it to work with ROS it listens for input on the speech_text topic and publishes the response on the speak_text topic. for testing
i don't use voice recognition just a keyboard it stops the family giveing me funny looks when i say the same thing over and over. Previously i found a blue tooth microphone works well but that is for another day. While the robot is talking it need more visual expression just having the jaw move up and down doesn’t work very well flashing lights with this head design won't work because of the solid color.
What would look cool are animated eyes via a LCD screen and maybe a RGB LED matrix for the mouth.
While chatting is one function the rest of the time the robot just sits there it may as well be a chair using Markov chains i can generate random sentences its jiberish but sort of makes sense. I want to have a control loop running that responds to activity and boredom like if nothing has happened for a while do a random move if the robot sees someone utter a Markov chain if he recognise a face say hello.
