Imagine what it would be like to have a robot friend who could take selfies, throw a ball, eat popcorn, and play air guitar.
Well, you might not have to wait too long.
Researchers at the University of Tokyo have created a robot that can do all of this, thanks to the power of GPT-4, the world's newest and most advanced large-scale language model (LLM).

What is the humanoid robot “Alter3”? How does it work?
Alter3 is a humanoid robot first introduced in 2016 as a platform to explore the concept of life in artificial systems. It has a realistic appearance and can move its upper body, head, and facial muscles in 43 axes controlled by air actuators. It also has a camera in each eye, allowing it to see and interact with humans and the environment.

But what's really special about Alter3 is that you can control its movement and behavior using GPT-4, a deep learning model that can generate natural language text from arbitrary prompts. This means that instead of programming every movement of the robot, the researcher can simply give the robot verbal instructions and have his GPT-4 generate the corresponding Python code that runs the Android engine.

For example, to have Alter3 take a selfie, a researcher could say:
“Sign a happy smile and open your eyes wide to show your excitement. Quickly rotate your upper body slightly to the left to adopt a dynamic posture. Raise your right hand high, imitating a telephone. Raise your right elbow. Bend over and bring the phone closer.'' Tilt your face slightly to the right to create a playful vibe. ”
GPT-4 then generates code that allows Alter3 to do just that.

What can Alter3 humanoid robots do with GPT-4?
Researchers tested Alter3 with GPT-4 in a variety of scenarios, including throwing a ball, eating popcorn, and playing air guitar. They also experimented with different types of feedback, including verbal, visual, and emotional, to improve the robot's performance and adaptability.

One of the most interesting aspects of Alter3's operation is that it can learn from its own memories and human responses. For example, if a robot does something that makes a human smile or laugh, it will remember it and try to repeat it in the future. This is similar to how a newborn baby imitates the facial expressions and gestures of its parents.

The researchers also added humor and personality to Alter3's action. In one case, the robot pretended to eat a bag of popcorn, only to realize that it belonged to the person sitting next to it. Then, with a surprised and embarrassed look on his face, he folds his arms and apologizes.

Why is this humanoid AI important and what are its implications?
The research team behind Alter3 says it is a breakthrough in the fields of robotics and artificial intelligence, showing that large-scale language models can be used to bridge the gap between natural language and robot control. I think this is a significant progress. This opens new possibilities for human-robot collaboration and communication, as well as for creating more intelligent, adaptable, and individualized robotic entities.

The paper, titled “From Text to Motion: GPT-4 Grounding in the Humanoid Robot Alter3,” was written by Takahide Yoshida, Atsushi Masumori, and Takashi Ikegami. Preprint server arXiv. The authors hope that their work will stimulate further research and development in this direction, and that one day we might have robot friends who can understand us and share our interests and emotions.

Cart important points
Alter3 is an example of how natural language processing and robotics can work together to create some of the most amazing interactions. GPT-4 allows robots to perform a variety of tasks and actions based on verbal commands without the need for extensive programming or manual control. This allows robots to learn from their own experiences and human feedback, and even express humor and personality. Alter3 shows the potential of large-scale language models to not only improve the fields of robotics and artificial intelligence, but also bring us closer to robot friends who empathize with and entertain us.
