Vision-Language Models for Scene Understanding
The system leverages Florence-2 for advanced object detection and open-vocabulary capabilities. This enables the robot to identify and localize objects based on natural language prompts (e.g., "green apple"), rather than predefined categories. This is crucial for dynamic, real-world environments and seamless integration with language commands. While a learning-based approach for end-effector detection was explored, ArUco markers proved more reliable for continuous, low-latency position estimates (30 FPS), forming a robust basis for motion planning.
Interpreting Intent with Large Language Models
LLaMA 3.1 (7B parameters) is at the heart of the system's semantic interpretation. It processes transcribed speech, extracts user intent, and translates it into structured, executable robot actions (e.g., move_object_to_left_of(apple, orange)). A carefully designed system prompt and a fixed temperature of T=0 ensure deterministic, reliable output, critical for precise robotic control, addressing the inherent variability often associated with LLMs in sensitive applications.
Robust & Precise Robotic Motion Control
Robotic motion is governed by an Interval Type-2 Fuzzy Logic System (IT2FLS), which explicitly models and accommodates uncertainty from sensor noise and actuation variability. Operating on positional errors (X and Y axes), the IT2FLS translates high-level action commands into smooth, precise movements. Compared to Type-1 FLCs, IT2FLS provides superior robustness and stability, making it ideal for real-world manipulation tasks where adaptivity is paramount.
Seamless Speech-to-Text & Wake-Word Detection
User interaction begins with continuous wake-word detection using a pre-trained Audio Spectrogram Transformer (AST), chosen for its low-latency and efficiency. Once activated, OpenAI's Whisper (small variant) performs robust speech-to-text (STT) transcription, converting spoken commands into textual form. This modular pipeline ensures the system remains responsive, hands-free, and minimizes computational overhead, serving as the primary input modality for intuitive human-robot communication.

Real-World Application: Dobot Magician Robotic Arm
This framework was rigorously tested on a Dobot Magician robotic arm equipped with a suction-based end-effector. The system successfully translated spoken commands into precise physical actions, demonstrated through tasks like identifying and picking up objects (represented by fruit photographs). The multimodal integration allowed the robot to interpret human intent (e.g., "grab the lemon") using LLaMA 3.1, perceive the scene with Florence-2 (detecting the lemon and user's hand), and execute adaptive movements via fuzzy logic control. This practical demonstration highlights the system's potential for intuitive object manipulation in dynamic environments. Example Scenario: User says "pick up the lemon," the system detects the lemon and user's hand, and the robot moves to pick up the lemon.
