Elon Musk's recent announcement on Twitter that "Tesla will have genuinely useful humanoid robots in low production for Tesla internal use next year" suggests that robots with human-like characteristics and practical functions might soon become a reality.
However, despite decades of efforts, genuinely useful humanoid robots have remained more fiction than fact. Are we finally on the verge of a breakthrough? And do we really need humanoid robots at all?
Tesla's Optimus robot is one of several emerging humanoid robots, alongside Boston Dynamics' Atlas, Figure AI's Figure 01, Sanctuary AI's Phoenix, and others.
These robots typically feature a bipedal design capable of walking, and sometimes even jumping, along with performing other athletic feats. Mounted on this platform are robotic arms and hands that can manipulate objects with varying degrees of dexterity and tactility.
Behind their "eyes" lies artificial intelligence designed for planning navigation, recognizing objects, and performing tasks.
The envisioned applications for such robots are numerous: working in factories to carry out repetitive, dirty, dull, and dangerous tasks; collaborating with humans, such as carrying a ladder together; serving in the service industry as "meet and greet" or "tour guide" robots; and even assisting in social care by lifting and moving individuals or providing personal care and therapy.
Interestingly, while humanoid sex robots face significant moral and ethical scrutiny, the use of humanoid robots in other areas generates less controversy.
Despite their potential, creating functional humanoid robots remains a significant challenge. Achieving flexible bipedal locomotion on various terrains is complex; it took humans millions of years to master this.
Similarly, dexterously manipulating objects of different shapes, sizes, and fragilities is difficult for robots. Companies like the UK's Shadow Robot have made significant strides in creating dexterous robotic hands, but these capabilities are still limited compared to the human hand, which is covered in a soft, flexible skin that continuously adapts to its environment.
Advancing from automating specific tasks to performing general tasks in a dynamic world requires significant progress in artificial intelligence, sensing, and mechanical capabilities.
Additionally, a humanoid robot that looks human is expected to communicate and respond emotionally like a human, but this is fraught with challenges. Without the ability to replicate the micro-expressions and non-verbal cues that humans subconsciously interpret, humanoid robots can come across as unsettling.
These are just a few of the many research challenges facing the global community of robotics and human-robot interaction researchers. Moreover, deploying humanoid robots in the real world, with its unpredictable conditions of rain, dust, and heat, adds another layer of complexity.
So, should we focus on building more robust systems that avoid the pitfalls humans face?
This raises the question of why Musk and others are fixated on humanoid robots. Must our robotic companions resemble us? One argument is that our world is designed to suit the human body. Our buildings and cities are constructed to accommodate our physical form, so it makes sense for robots to take on a similar shape.
However, our built environments and tools often assume a certain level of strength, dexterity, and sensory ability, which can disadvantage many people, including those with disabilities. Could the rise of stronger metal machines further perpetuate this divide?
Perhaps we should view robots as part of a broader effort to create a world that better accommodates the diversity of human bodies. Integrating robotics technologies into our buildings, furniture, tools, and vehicles to make them smarter and more adaptable could make them more accessible for everyone.
It's notable that current robot designs fail to reflect the diversity of human bodies. Our obsession with humanoid robots might have deeper roots, perhaps reflecting a god-like desire to create versions of ourselves, a fantasy often explored in dystopian science fiction.
Alternatively, humanoid robots might be a "moonshot"—an ambitious vision that drives impressive engineering innovations, even if we’re not entirely sure why we’re pursuing it.
