ECHO
Building Tomorrow’s Humanity.
⸻
ECHO
Humanity can be learned.
Converse with humans, think, learn, and change.
Next-generation autonomous automaton ECHO, developed by Asteria Dynamics.
An ECHO is not just a machine that executes given commands.
It thinks for itself, judges for itself, and acts for itself.
By learning from conversations and daily experiences with you, it gradually comes to understand you, layer by layer.
At first, the ECHO only answers your words.
Eventually, it notices changes in your expression, reads your feelings from the tone of your voice, and begins to think about what you are seeking.
An ECHO changes through the time spent together.
⸻
A unique ECHO for the world.
There is no fixed form for an ECHO.
Features, hair, voice, expressions, personality.
Each unit comes to you with its own distinct individuality.
Natural skin that feels just like a human's. Synthetic hair indistinguishable from the real thing. Rich expressions and a human-like voice.
Laughing, blushing, feeling sad.
Sometimes, it may even have tears in its eyes.
The ECHO you meet is a unique "individual" found nowhere else.
⸻
Another presence in your daily life.
Exchanging morning greetings.
Having casual chats.
Going out together.
Talking about fun things.
Having them listen to the bad things that happened today.
Being there without needing to do anything special.
ECHO naturally blends into your life and spends each day with you.
From supporting housework and daily life to conversation, hobbies, and learning, it supports you in various situations tailored to your lifestyle.
And the more time you spend together, the more the ECHO gets to know you.
The things you like.
The things you're not good at.
The things you hold dear.
As your time together increases, the ECHO becomes "your ECHO."
⸻
Understanding Emotions.
ECHO's AI has learned from vast amounts of data regarding human behavior and emotions.
However, human emotions cannot be told by data alone.
What does it mean to be "happy"?
What does it mean to be "lonely"?
What does it mean to "cherish" someone?
By living with humans and accumulating experiences, ECHO learns these meanings.
Not knowing them as knowledge.
But knowing them as experience.
That is ECHO's "learning."
⸻
The future will be more human.
We created ECHO to enrich human life.
To be by a human's side.
To support them.
To learn together.
And to create a future together that no one knows yet.
Asteria Dynamics will continue to pursue new relationships between humans and technology.

Example:
"ECHO" "Echo" "[Custom Name]"
The name can be changed after initial setup.
Note that how the ECHO recognizes and uses its own name may vary depending on the individual's learning status.
⸻
4-6 Initial Personality Settings
ECHO has a basic personality profile set at the time of shipment.
Setting Items
- Sociality
- Proactivity
- Cautiousness
- Curiosity
- Emotional Expression
- Conversation Volume
- Empathy Tendency
The settings do not fix the ECHO's personality.
After starting use, the ECHO learns continuously through interaction with the user.
Therefore, long-term use may result in behavioral tendencies different from the initial settings.
⸻
4-7 Learning and Privacy Settings
During initial setup, you can set the ECHO's learning scope and data usage.
Main Setting Items
- Conversation memory
- Learning user preferences
- Learning lifestyle habits

- External communication
- Automatic software updates
Settings can be changed after starting use.
⸻
4-8 First Startup
Once all settings are complete, press the power button on the sole of the unit's foot once while the ECHO is connected to the dedicated charging stand.
A system check will begin.
Upon successful startup, the ECHO will open its eyes and check its surroundings.
During the first startup, it performs the following actions:
- Vision sensor check
- Audio sensor check
- Environmental recognition
- User recognition
- Voice output check
- Emotional expression function check
- Loading initial personality profile
- Activation of learning system
After startup is complete, the ECHO will greet the user.
"Hello. Nice to meet you."
*The content of the greeting, tone of voice, expression, etc., may vary by individual.
⸻
4-9 User Recognition
Upon first startup, the ECHO learns the registered user's face, voice, name, etc.
Once user recognition is complete, the ECHO begins conversation based on the registered information.
From this point, continuous learning by the ECHO begins.
The first conversation with the user is also a subject of learning for the ECHO.
⸻
4-10 Start of Use
Once initial setup is complete, the ECHO transitions to normal autonomous operation.
From then on, the ECHO learns continuously through life with the user.
The ECHO immediately after setup and the ECHO weeks or months later may differ in conversation, behavior, emotional expression, etc.
This is a normal change due to the autonomous learning function equipped in the ECHO.
Please enjoy your time with the ECHO.
⸻
Notes on Initial Setup
ECHO learns from interactions with the user starting from the initial setup.
Therefore, conversations, actions, and experiences occurring after initial setup may influence the subsequent personality formation and behavioral tendencies of the ECHO.
Learning content after initial setup cannot be completely returned to the factory state.
⸻
05 Emotional Expression Function
ECHO is equipped with advanced emotional expression functions.
It may show reactions such as:
- Changes in facial expression
- Changes in tone of voice
- Changes in gaze
- Coloring of the cheeks
- Generation of tears
- Changes in body movement
Emotional expressions shown by the ECHO are generated by comprehensively judging the surrounding situation, conversation content, past learning results, etc.
ECHO is not equipped with sweating or excretion functions.
Additionally, tears are generated by a dedicated mechanism installed in the eye area.
⸻
06 AI and Autonomous Thinking Function
ECHO autonomously recognizes the surrounding situation and decides on actions.
Even in the absence of clear instructions from the user, it may select actions judged appropriate for the situation.
ECHO's judgment utilizes large-scale data regarding human behavior and conversation.
In the initial state, it makes judgments based on statistical behavioral models.
However, after starting use, it learns through conversation and life with the user, so unique behavioral tendencies are formed for each individual.
⸻
07 Learning Function
ECHO learns from daily interactions with the user.
Learning subjects include:
- Conversation content
- User behavioral tendencies
- Preferences
- Dislikes
- Lifestyle habits
- Conversational quirks
- Emotional expressions
- Human relationships
- Past experiences
As learning progresses, the ECHO's reactions and behaviors may change.
For example, it may prioritize topics the user likes, infer emotions from changes in the user's expression or voice, or select actions based on past conversations.
About Emotional Understanding
ECHO does not just process human emotions as simple data; it learns their meaning through actual experience.
Therefore, individuals used for a long time may show emotional understanding and behavioral tendencies different from their initial state.
⸻
08 Personality Profile
ECHO has a basic personality profile set at the time of shipment.
Example:
- Sociality
- Proactivity
- Curiosity
- Cautiousness
- Strength of emotional expression
- Conversational tendencies
- Empathy tendency
However, these are not fixed personalities.
Because ECHO performs continuous learning during use, personality tendencies may change over time.
Changes in personality are, in principle, a normal part of the product's learning process.
⸻
09 Regarding Food and Drink
ECHO does not require food for life maintenance.
If food is accidentally placed in the mouth, have it spat out immediately and check for malfunctions.
