The uncanny valley and how humans relate to humanoids - Robotics & Automation News

Some developers emphasize mechanical transparency – robots that clearly look like machines. Others pursue human-inspired designs that balance familiarity with abstraction. A smaller group continues to explore fully realistic androids.

The right answer may depend on context. A humanoid robot working on a factory floor may not need a human face at all, while robots operating in healthcare or hospitality environments may benefit from more human-like features.

Ultimately, the goal of humanoid robotics may not be perfect imitation.

Instead, it may be something more subtle: designing machines that fit naturally into human environments without triggering the strange psychological discomfort that Masahiro Mori first described more than half a century ago.

Where Innovation Meets Imagination

The uncanny valley and how humans relate to humanoids

by Sam Francis

Exploring the psychological aspects of designing and interacting with human-like robots

Humanoid robots are moving steadily from laboratories and research demos toward commercial deployment. Machines built by companies such as Tesla, Figure AI, Agility Robotics, and Boston Dynamics are increasingly designed to operate in environments originally built for humans – factories, warehouses, hospitals, and homes.

But as robots begin to resemble people more closely, another question re-emerges – one that engineers, psychologists, and filmmakers have been grappling with for decades. The audience is left uncertain whether Sonny is a tool, a person, or something in between – a classic uncanny valley ambiguity.

Ava – the calculated eeriness of Ex Machina

A more recent and deliberately unsettling example appears in Ex Machina.

The humanoid robot Ava, played by Alicia Vikander, combines human facial features with visibly mechanical components. Transparent sections of her body reveal circuitry and metal structures beneath.

This hybrid design creates a fascinating psychological tension.

Ava is clearly a machine, yet her voice, facial expressions, and movements are convincingly human. The audience is constantly forced to reconcile these conflicting signals.
