Semantic Engine - What NAO knows¶
| Prerequisite: Autonomous Life: ON - Basic Channel: ON |
Warning
Semantic Engine is an experimental feature, it is not active by default. To activate it, use _enableSemanticFallback method of ALDialog.
NAO can learn!¶
Thanks to his Semantic Engine, NAO is able to:
- keep in mind some information,
- acquire new information, and
- use this knowledge in order to answer your questions and requests.
Note
For now, NAO has a short-term memory, persistent from startup to shut-down. He will forget all his knowledge each time he reboots.
Test NAO’s ability to learn¶
When chatting with NAO, try to make some simple assertions, then question him.
Example:
Human: Paul likes to play video games.
Human: what does Paul like?
Robot: Paul likes to play video games.
Tips:
You can also use “I” and “you”.
Human: I like chocolate.
Human: what do I like?
Robot: You like chocolate.
You can change your mind!
Human: Paul likes to play video games
Human: what does Paul like?
Robot: Paul likes to play video games.
Human: Paul doesn't like to play video games
Human: what does Paul like?
Robot: Paul likes nothing particular.
NAO is able to follow conditional assertions.
Syntax:
if/when/whenever <condition> , <affirmation>
Example:
Human: If Paul likes chocolate, Paul likes banana
Robot: OK, Paul likes the banana if he likes chocolate.
Human: Does Paul like banana
Robot: I don't know if Paul likes the banana.
Human: Paul likes chocolate
Human: Does Paul like banana
Robot: Yes, Paul likes the banana.
Question NAO about his perceptions¶
You can question NAO about his perceptions.
Example:
<the human doesn’t touch NAO’s left hand>
Human: is your left hand touched?
Robot: No, my left hand is not touched.
<the human touches NAO’s left hand>
Human: is your left hand touched?
Robot: Yes, you touch my left hand.
Train NAO¶
On your request, NAO is able to perform some basic actions.
Example:
Human: raise your left hand.
<NAO raise his left hand>
For further details, see: Make NAO move.
You can also teach him new actions.
Syntax:
<infinitive command to define> means <set of infinitive(s) command(s) to do>
Example:
Human: to salute means to say hello
Robot: OK, to salute means to say hello.
Human: salute
Robot: Hello
NAO is also able to learn how to react in some circumstances.
Syntax:
if/when <condition> , <command>
Example:
Human: if I am happy, raise your left hand
Robot: OK, I will raise my left hand if you are happy.
Human: I am happy
<robot raises his left hand>
Human: I am happy
<robot doesn't raise his left hand>
