Chapter 1: Introduction to Ameca

Ameca, developed by Engineered Arts Ltd, isn’t the most advanced robot in terms of intelligence or functionality. It lacks the ability to engage in deep conversations or perform tasks. Yet, its striking resemblance to human beings has captured the public's imagination, leading to its viral fame.

Typically, discussions surrounding AI and robotics focus on attributes such as intelligence, agility, and communication skills. However, we often overlook the field dedicated to the study of appearance, known as anthrobotics. This branch aims to create robots that authentically replicate human expressions, gestures, and emotions.

Most AI research tends to prioritize the creation of highly intelligent, disembodied agents (like GPT-3 or AlphaZero). Intelligence is often regarded as the hallmark of humanity and is seen as the most advantageous trait to incorporate into robots. Nonetheless, AI systems exist within a broader context; they are woven into our daily lives, and we may soon find ourselves interacting with physical robots powered by these AI systems.

A crucial question arises: Should these robots resemble humans? Enhancing robots' ability to communicate and connect with people is essential for fostering a relationship between them and humans.

Ameca, unveiled at CES 2022, is a humanoid robot designed to be hyper-realistic by the UK-based company Engineered Arts. This robot made its debut in late 2021 and quickly gained attention with this video:

Chapter 2: The Human-Like Characteristics of Ameca

Ameca’s expressive capabilities are striking. For instance, when it opens its eyes in astonishment and scans its surroundings, it mirrors how humans react when abruptly awakened. The robot curiously examines its own arm, embodying feelings of awe and wonder—complex emotions that resonate with us.

Yet, despite its human-like features, Ameca remains distinctly non-human, with gray, translucent skin and robotic limbs made of metal and plastic. Morgan Roe, the director of operations at Engineered Arts, shared with CNET that the design intentionally leans towards a less human appearance to avoid evoking fear. The company's other line of robots, Mesmer, attempts to emulate human likeness more closely, often resulting in an uncanny valley effect that can be unsettling.

Ameca is not just human-like; it exudes a sense of friendliness that makes it approachable—something you might feel comfortable allowing your children to interact with. The goal may not be to create robots that are entirely human but to ensure they have human-like qualities, especially in their facial expressions, while maintaining artificial elements, like skin color. Ameca strikes this delicate balance, making it ideal for roles requiring non-verbal communication.

However, Ameca remains a prototype, and its current form might be one reason for its popularity. The perception would likely shift if we encountered numerous units performing mundane tasks in our neighborhoods. Encountering a Mesmer robot on a lonely street late at night could be far more unsettling. While Ameca represents the forefront of humanoid robotics, it is not yet ready for mass production.

In the future, such robots could help bridge the gap between humans and technology. I have previously argued for making AI and robots more human-like. If we are to coexist with robots, they should be designed to be visually appealing and pleasant.

For now, we need not worry about these developments, as we are still far from realizing such scenarios. While Ameca may appear human, its intelligence is vastly limited. Unlike advanced AI models like AlphaZero or GPT-3, it lacks sophisticated cognitive abilities and is not built for mobility. Unlike Boston Dynamics' Atlas, you won't see Ameca performing acrobatic feats.

Imagine if we could combine Ameca’s design with GPT-3’s linguistic capabilities, AlphaZero’s learning algorithms, Atlas’ physical dexterity, and the situational awareness of self-driving cars. That combination would bring us closer to the robot depicted in "I, Robot." The future of robotics lies at the intersection of these advancements, involving human-like expressions, fluid movements, and exceptional language skills—features we have yet to achieve even in isolation.

Chapter 3: Challenges and Considerations

Ameca is still far from this ideal, and Engineered Arts faces numerous challenges in reaching that goal. One significant concern is the well-known anthropomorphization bias. People often ascribe full humanity to robots that exhibit enough human traits. For example, if a robot’s facial expressions perfectly mimic ours, individuals may incorrectly assume it possesses the same mental states that generate those expressions. The same applies to language models; coherent and persuasive text can lead readers to infer intent where none exists.

Neither Ameca’s smile nor the prose of AI carries any intention or emotional depth.

Our brains are wired to make predictions based on expectations. If we misinterpret a robot with a curved mouth and shiny eyes as having genuine feelings, the implications could be significant. We might end up entrusting critical responsibilities, such as caring for children, to a machine—a possibility that is extreme yet not entirely implausible.

The essential policy regarding the future of humanoid robots is to educate the public on their capabilities and limitations. While this alone may not eliminate negative outcomes, it is a crucial step for those of us in the AI education field.

For the time being, we can appreciate Ameca’s expressive features and share its captivating videos across social media platforms.
