4WD Robot Chassis 3D Printed DIY Kit - Orange/Black Robotics Base

Specifications:

• Drive Type: 4-Wheel Drive (4WD)
  
• Manufacturing: FDM 3D Printed
  
• Chassis Plates: Dual-layer (Orange Base, Black Top)
  
• Motors: 4x Yellow DC Gear Motors (typically 3V–6V)
  
• Wheels: 4x High-traction rubberized tires with yellow rims
  
• Hardware: Includes 6x long assembly screws for structural support
  

Key Applications & Projects

• Line Following Robot: Adding IR sensors to the front of the orange chassis plate for high-speed path tracking.
  
• Obstacle Avoidance Car: Mounting an ultrasonic sensor on the integrated front bracket to navigate complex environments.
  
• Bluetooth Remote Control: Pairing with an ESP32 or HC-05 module for smartphone-controlled driving.

Project Evolution

• Customization Upgrade: Because the chassis is 3D printed, you can easily design and print your own specialized sensor mounts or camera gimbals to attach to the existing structure.
  
• Power Upgrade: Transition from standard AA batteries to a Li-ion setup for significantly improved motor performance and longevity.
