RoboRover Hardware Breakdown: Building an AI Robot from Salvaged Parts | Episode 2

Описание: Complete hardware breakdown of RoboRover—built from salvaged parts, 3D printed chassis, and cheap components. Here's exactly what's inside this AI-powered autonomous robot.

🔧 What's Inside RoboRover?
A detailed component-by-component tour showing how affordable hardware and salvaged parts can create a functional AI robot. No expensive custom PCBs, no exotic components—just smart assembly.

⚡ Power System:
• Salvaged power bank (broken shell, working board!)
• Dual USB outputs: 5V 1A (ESP32) + 5V 2A (PCA9685)
• 2x 470µF 10V capacitors for power stabilization
• 18650 battery cells from original power bank

🔩 Motors & Movement:
• 4x SG90 continuous rotation servos (wheel drive)
• 1x SG90 standard servo (180° lidar rotation)
• PCA9685 16-channel PWM servo controller
• I2C bus for clean wiring

🏗️ Chassis & Structure:
• 3D printed modular chassis boards
• M3 screw grid pattern for flexible mounting
• 3D printed wheels
• Rubber strips from old bike tire for traction
• Fully customizable layout

🧠 Electronics & Sensors:
• ESP32 microcontroller (WiFi + dual-core)
• VL53L0X Time-of-Flight lidar sensor
• MPU6050 IMU (accelerometer + gyroscope)
• All sensors on shared I2C bus
• USB cables & jumper wires for connections

💡 Key Takeaways:
✅ Salvaged parts work great (broken power bank!)
✅ 3D printing makes it modular and customizable
✅ Standard hobby components (SG90 servos, ESP32)
✅ DIY traction solution (bike tire rubber)
✅ Simple I2C wiring (daisy-chain sensors)
✅ No special tools needed (screwdriver + basic soldering)
✅ Total cost: ~$40-60 if you have salvaged parts

🎯 Bill of Materials:
• ESP32 DevKit: ~$8
• 5x SG90 Servos: ~$10
• PCA9685: ~$5
• VL53L0X Lidar: ~$5
• MPU6050: ~$3
• Power Bank: Salvaged (or ~$10)
• 3D Printed Parts: ~$5 in filament
• Wires & Screws: ~$5
• Bike Tire Rubber: Salvaged (free!)

🔨 Assembly Tips:
• Mount motors before wiring
• Test each servo individually first
• Use cable management (zip ties or 3D clips)
• Check I2C address conflicts before assembly
• Power everything off external battery during testing

🌟 Why This Matters:
You don't need expensive kits or custom parts to build an AI robot. With salvaged components, 3D printing, and cheap hobby electronics, you can create a robot that runs real AI models and explores autonomously.
