• Speech Recognition & Synthesis: Social robots can understand spoken language and respond with their own pre-programmed greetings.
• Machine Learning & Artificial Intelligence (AI): Advanced social robots leverage machine learning algorithms to adapt their greetings based on various factors. They can analyze the time of day, the person’s appearance, or even previous interactions to personalize their greeting style.
• Non-Verbal Communication: Some social robots can utilize non-verbal cues to enhance their greetings. This might include body language like nods or waves, facial expressions like smiles, or even eye contact simulation using built-in displays.

These combined capabilities allow social robots to greet people in a way that feels natural and engaging, paving the way for more meaningful human-robot interaction.

Examples of Robots that Can Greet People

Many social robots available today possess the capabilities to greet people in various ways. Here’s a look at some of the robots you mentioned and their greeting functionalities:

1. NAO (SoftBank Robotics): NAO is a powerful humanoid robot well-suited for educational settings. It can greet people using pre-programmed verbal greetings, recognize facial expressions, and even personalize greetings based on the time of day. Additionally, NAO can utilize body language like nods and waves to enhance its greetings.
2. Pepper (SoftBank Robotics): Pepper, NAO’s larger sibling, excels in social interaction. Its advanced capabilities allow it to greet people with a wider range of emotions and expressions. Pepper can personalize greetings based on the person’s age, gender, or even their mood, making them feel welcome and comfortable.
3. Double 3 (Double Robotics): While not a humanoid robot, Double 3 offers a unique take on greetings. This telepresence robot allows users to control its movements and interact with people remotely. Double 3 can be programmed with various greeting messages and can even tilt its screen to simulate eye contact, creating a welcoming presence despite the physical distance.
4. BellaBot (Keenon Robotics): This service robot is primarily designed for deliveries in restaurants or hotels. However, BellaBot can also greet customers upon entering the establishment. It can play pre-recorded greetings or even display custom messages on its built-in screen, setting a positive tone for the customer experience.
5. KettyBot (Techman Robot): KettyBot is an industrial robot repurposed for service applications. While not specifically designed for social interaction, some KettyBot models can be programmed with simple verbal greetings to acknowledge people entering its designated area. This functionality can be particularly useful in situations where safety is a concern.

These are just a few examples, and the list of robots capable of greeting people is constantly growing. As social robotics technology advances, we can expect even more sophisticated and natural-feeling greetings from robots in various settings.

How Do Robots Greet People? Exploring Different Greeting Styles

Social robots greet people in a variety of ways, depending on their programming and functionalities. Here are some common greeting styles:

• Simple Verbal Greetings: This is the most basic form of a robot greeting. The robot might simply say “Hello” or “Good morning” upon detecting a person’s presence.
• Personalized Greetings: More advanced robots can personalize their greetings based on the person or the situation. They might use the person’s name (if it’s been programmed), acknowledge the time of day (“Good afternoon”), or even offer a situational greeting (“Welcome to the store!”).
• Interactive Greetings: Some robots take their greetings a step further by incorporating interactive elements. They might ask a simple question (“How can I help you today?”), offer a choice of greetings (“Hi there! How are you doing today?” or “Good morning! Welcome back!”), or even incorporate humor or light conversation starters.
• Non-Verbal Cues: As mentioned earlier, some robots can enhance their greetings with non-verbal cues. This adds a layer of friendliness and makes the interaction feel more natural. Imagine a robot waving hello while saying “Welcome!” or tilting its head in curiosity while asking “How can I assist you?”

These are just a few examples, and the possibilities for robot greetings are constantly evolving. As technology advances, we can expect even more sophisticated and natural-feeling greetings from social robots.

Benefits and Applications: Why Do Robots Need to Greet People?

The ability to greet people isn’t just a party trick for robots. It offers a range of benefits and unlocks various practical applications across different sectors:
