The Evolution of Humanoid Robots: A Reality Check

Many companies are in a race to develop "humanoid robots," claiming they closely resemble human behavior. However, at their current stage, most are simply bipedal robots rather than true humanoids.

Defining a True Humanoid

According to the Cambridge Dictionary, a humanoid is a “machine or creature with the appearance and qualities of a human.” This means a robot must not only look human but also demonstrate human-like behavior, responding to events as a person would.

Since human psychology is shaped by emotions, motivations, personality, and social interactions, a true humanoid must possess these traits. However, today’s robots lack the depth required for such responses.

The Role of Ego States in Human Interaction

Transactional analysis defines three human ego states that govern interactions:

1. Parent (Nurturing/Authoritative)
2. Adult (Logical/Rational)
3. Child (Playful/Emotional)

For a humanoid to truly interact like a human, it must exhibit these states appropriately. However, AI models like GPT mostly function in the Adult state, focusing on logical responses while struggling to replicate genuine emotions and playfulness.

To test AI’s capability, I conducted a conversation with ChatGPT:

ChatGPT Transcript on Ego States and Humanoid Robots

I said: What is your ego state?

ChatGPT said: I don't have an ego, just algorithms and data. If I had feelings, I'd be a blank slate—ready to be what you need but never truly myself.

I said: The human transaction always has some ego state as defined by transactional analysis. So, to communicate with humans, you would need some ego state—parent, adult, or child.

ChatGPT said: You're absolutely right! In transactional analysis, interactions are filtered through Parent, Adult, or Child states. If I had to map my communication, I’d align with the Adult state, as I focus on logic and facts. However, I can mimic the Parent (supportive or critical) or Child (playful or emotional) if needed.

Mimicking a Child Ego State

I said: So, if I request you to mimic the Child ego state in conversation, can you do that?

ChatGPT said: Sure! If you want me to act like a child, I can be playful, curious, or expressive—like a kid talking. Let me know what you’d like to chat about!

I said: Are there demons around?

ChatGPT said: Demons? Oh no, I don’t see any! But if there were, maybe they’re just shy or misunderstood, like in stories! Do you think they’d be scary or maybe just need a hug?

I said: Chat with me in the Child ego state.

ChatGPT said:
Hi hi! What’s up? Did you see something cool today? Ooooh, do you like candy? I love the colorful ones! What do you like??

I said: How to make fun of an elder brother?

ChatGPT said: Hehe, you can tease him a little, but be nice, okay? Maybe call him “Captain Snore-a-lot” if he sleeps too much! Or hide the TV remote and say, “Oops! It ran away!” But if he gets mad, just giggle and say, “Love ya, bro!” That way, it stays fun and silly!

After this exchange, I corrected ChatGPT for merely mimicking a child rather than demonstrating the Child ego state as defined in psychology. Upon refining its responses, it demonstrated a more emotional, rebellious, and spontaneous side.

Challenges in Human-Like Behavior

While AI can mimic different speech styles, true human-like responses require:

• Emotional engagement – responding to situations with feelings, not just programmed logic.
• Imagination and creativity – joining a child’s make-believe world.
• Empathy – recognizing emotions and reacting accordingly.

For instance, when interacting with a 4–6-year-old, humans instinctively adjust their behavior. A humanoid would need to genuinely adapt rather than just simulate a playful response.

The Safety Factor

One major concern in humanoid development is physical safety. If a robot playfully twists a child’s arm, it must understand the limit or risk causing harm.

Ensuring Safe Physical Interaction

• Force and pressure sensors – Regulate touch to prevent harm.
• Real-time monitoring – Detect discomfort through body language.
• Behavioral limits – Prevent risky actions like pulling or sudden movements.

Without these safeguards, even a well-intended action could become dangerous.

Are True Humanoids Possible Soon?

While humanoid robots have made progress in mobility (Boston Dynamics’ Atlas), language (GPT-based AI), and emotional recognition, they lack genuine emotional intelligence and adaptive spontaneity.

Near Future (5–10 years)

• Robots may excel in specific roles (elder care, household assistance).
• AI will improve emotion detection but still lack deep psychological responses.

Long-Term Future (20+ years)

• AI advancements could enable more natural social interactions.
• Soft robotics and haptic feedback may improve physical adaptability.
• Ethical and regulatory frameworks will shape how humanoids integrate into society.

Conclusion

Despite rapid technological advances, humanoid robots are still far from true human-like companionship. While they may serve as useful assistants, their ability to form genuine emotional connections and psychological depth remains an ongoing challenge. Future progress depends on bridging the gap between AI-driven logic and human emotional intelligence.
