How to use ChatGPT in Robotics

In recent years, advances in Artificial Intelligence (AI) have revolutionized the field of robotics, enabling the development of robots that can not only perform complex physical tasks, but also interact with humans in increasingly sophisticated ways. One powerful tool in the development of these communication capabilities is OpenAI’s ChatGPT. Let’s see how ChatGPT can be utilized in robotics.

What is ChatGPT?

ChatGPT is an AI language model developed by OpenAI. It’s designed to generate human-like text based on the input it receives. It’s capable of carrying on a conversation, making it ideal for tasks such as drafting emails, writing articles, tutoring, translating languages, and even simulating characters for video games. It is not the only model capable of doing that, we can’t forget about Bing, Bard and other models… but so far ChatGPT has showed to be the most reliable model, especially with the ChatGPT 4 model which is not free though.

How to Use ChatGPT in Robotics

To use ChatGPT in a robotic system, we need to integrate it into the robot’s software. This process can vary significantly depending on the specifics of the robot, but here are the general steps:

Establish a Connection: The first step is to set up a communication link between your robot’s control system and the ChatGPT API provided by OpenAI. This typically involves writing a software module in the robot’s control software that can send requests to the API and process the responses.
Text-to-Speech and Speech-to-Text Systems: For a robot to verbally communicate with humans, you’ll need to implement text-to-speech (TTS) and speech-to-text (STT) systems. The STT system will convert spoken input from humans into text that can be processed by ChatGPT, and the TTS system will convert the text responses from ChatGPT into spoken words.
Creating Interactive Behaviors: Once you’ve established a connection with the API and set up TTS and STT systems, you can start building interactive behaviors. For example, you could program the robot to ask for user input, send the input to the ChatGPT API, and then respond verbally using the generated text.

Practical Applications of ChatGPT in Robotics

Integrating ChatGPT with robotics can open up a world of possibilities. Here are just a few examples:

Customer Service Robots: ChatGPT can empower robots to handle customer service tasks, answering queries in retail stores, restaurants, or other customer-facing environments.
Educational Robots: Robots equipped with ChatGPT can be used in educational settings to tutor students in various subjects, offering explanations, answering questions, and even providing feedback.
Healthcare Robots: ChatGPT could enable robots to assist in healthcare settings, helping to take patient histories, provide information about medical conditions, or remind patients to take their medication.
Companion Robots: Robots can use ChatGPT to engage in meaningful conversation, providing companionship, entertainment, and even mental health support.

Limitations and Potential Benefits

While the integration of ChatGPT into robotics presents significant opportunities, it is currently not as powerful as it sounds.

It definitely adds to the robot a whole new function that makes the robot being able to speak with human, which is good, but this function isn’t much different from the virtual assistants we already have. It would be great if this ability to understand human language could be used to tell the robot what to do inside a certain environment, but unless it was already pre-programmed to be in a certain pose under a certain command, the robot wouldn’t be able to do that.

The positive side is that, assuming the robot is pre-programmed to do a certain task under a certain command, we could use ChatGPT so that we don’t need to remember that exact command anymore. Commands like clapping hands twice or saying a specific word like “Water” for, let’s say bringing a cup of water, might be substituted to an infinite range of more human-like commands like “Bring me some water please”, “Bring me a cup of water please” and so on…

Conclusion

The use of ChatGPT in Robotics has its own limitations yet but might already be a solution to improve the interaction between humans and robots making it more human-like. We are still far from the robot being able to understand the task without being already pre-programmed to do that but we are definitely a step closer to that.
