Chapter 04: Social Robotics

Overview

This chapter explores social robotics—robots designed to interact with humans in social contexts. Understanding human psychology, social cues, and emotional intelligence is crucial for creating robots that people want to interact with.

Learning Objectives

• Understand social robot design principles
• Learn about emotional expression and recognition
• Explore human psychology in HRI
• Understand social norms and etiquette
• Master techniques for natural social interaction

Core Concepts

1. Social Robot Design

Design Principles:

Principle	Description	Example
Anthropomorphism	Human-like appearance	Humanoid face
Expressiveness	Show emotions	Facial expressions
Proxemics	Personal space	Maintain distance
Gaze	Eye contact	Look at user
Gestures	Body language	Nodding, pointing

2. Emotional Intelligence

Emotion Recognition:

class EmotionRecognizer:
    def __init__(self):
        self.model = load_emotion_model()
    
    def recognize(self, face_image, voice_audio):
        # Facial emotion
        face_emotion = self.model.predict_face(face_image)
        
        # Vocal emotion
        voice_emotion = self.model.predict_voice(voice_audio)
        
        # Fused emotion
        emotion = self.fuse(face_emotion, voice_emotion)
        
        return emotion

3. Social Norms

Cultural Considerations:

Aspect	Western	Eastern	Robot Adaptation
Personal Space	Large	Small	Adaptive
Eye Contact	Direct	Indirect	Context-dependent
Gestures	Expressive	Subtle	Cultural awareness

Summary

Key takeaways:

• Social robots must understand human psychology
• Emotional intelligence improves interaction
• Cultural awareness is essential
• Social norms guide robot behavior
• Natural interaction builds acceptance
