While many humanoid robots are still in the prototype phase or other early stages of development, a few have escaped research and development in the last few years, entering the real world as bartenders, concierges, deep-sea divers and as companions for older adults. Some work in warehouses and factories, assisting humans in logistics and manufacturing. And others seem to offer more novelty and awe than anything else, conducting orchestras and greeting guests at conferences.
What Are Humanoid Robots?
How Are Humanoid Robots Being Used Today?
While more humanoid robots are being introduced into the world and making a positive impact in industries like logistics, manufacturing, healthcare and hospitality, their use is still limited, and development costs are high.
That said, the sector is expected to grow. The humanoid robot market is valued at $1.8 billion in 2023, according to research firm MarketsandMarkets, and is predicted to increase to more than $13 billion over the next five years. Fueling that growth and demand will be advanced humanoid robots with greater AI capabilities and human-like features that can take on more duties in the service industry, education and healthcare.
In light of recent investments, the dawn of complex humanoid robots may come sooner than later. For instance, AI robotics company Figure and ChatGPT-maker OpenAI formed a partnership that’s backed by investors like Jeff Bezos. Under the deal, OpenAI will likely adapt its GPT language models to suit the needs of Figure’s robots. And microchip manufacturer Nvidia revealed plans for Project GR00T, the goal of which is to develop a general-purpose foundation model for humanoid robots. These announcements come in the wake of Elon Musk and Tesla introducing the humanoid robot Optimus in 2022, although the robot remains in the production phase.
How Are Humanoid Robots Being Used?
- Hospitality: Some humanoid robots, like Kime, are pouring and serving customer drinks and snacks at self-contained kiosks in Spain. Some are even working as hotel concierges and in other customer-facing roles.
- Education: Humanoid Robots Nao and Pepper are working with students in educational settings, creating content and teaching programming.
- Healthcare: Other humanoid robots are providing services in healthcare settings, like communicating patient information and measuring vital signs.
But before companies can fully unleash their humanoid robots, pilot programs testing their ability to safely work and collaborate alongside human counterparts on factory floors, warehouses and elsewhere will have to be conducted.
It’s unclear how well humanoid robots will integrate into society and how well humans will accept their help. While some people will see the proliferation of these robots as creepy, dangerous or as unneeded competition in the labor market, the potential benefits like increased efficiency and safety may outweigh many of the perceived consequences.
Either way, humanoid robots are poised to have a tremendous impact, and fortunately, there are already some among us that we can look to for guidance. Here are a few examples of the top humanoid robots working in our world today.
