Kinect-Based Motion Control for Low-Cost Robotics Using WIZnet W5100

Traditional robot control systems rely on physical controllers or costly sensors, limiting accessibility. This project leverages Microsoft Kinect’s motion tracking to control a RoboSapien toy robot via Ethernet (WIZnet W5100), demonstrating an affordable alternative to high-cost motion-controlled robotics.

🚀 By integrating Kinect, W5100 Ethernet Shield, and Arduino, this project enables hands-free robot control over the network!

🛠 Project Overview

• MCU Used: Arduino + W5100 Ethernet Shield
• Networking Modules: WIZnet W5100 (Hardware TCP/IP stack)
• Software & Protocols: OpenFrameworks (C++), POCO Networking, Kinect SDK
• Purpose: Motion-controlled robotic system using network-based control
• Main Use Cases: Human-Robot Interaction, Gesture-Based Control, Robotics Education

📌 Why WIZnet W5100? Key Advantages

🔹 Ethernet-Based Real-Time Control
Instead of relying on Bluetooth or WiFi, this project uses a stable wired Ethernet connection (W5100) for low-latency control of the robot.

🔹 Seamless Arduino Integration

• SPI-based communication between Arduino & W5100 for simple yet powerful network communication.
• Supports DHCP or static IP for flexible deployment.

🔹 Hardware-Based Networking for Stability

• Offloads TCP/IP processing to W5100, reducing Arduino’s processing load.
• Maintains stable communication without wireless interference.

📌 System Architecture: Kinect + W5100 for Networked Robot Control

🔗 How It Works

1️⃣ Kinect SDK extracts user's skeleton motion
2️⃣ Motion data is translated into movement commands
3️⃣ PC sends commands over Ethernet (WIZnet W5100)
