Description
The Servo Steering Car Chassis features a professional-grade steering mechanism modeled after remote control racing cars. Unlike typical differential-steering chassis, this design uses a rear-wheel motor drive with a front Ackermann steering mechanism, two pull rods connected to a servo control the front wheels for precise left and right turns . The single motor is secured by an integral die-cast aluminum fixing piece that tightly engages the transmission shaft, while two flanged bearings ensure smooth rotation . Two acrylic mounting plates on top provide space for securing a mainboard, motor driver, and battery, making this chassis suitable for robotics projects and DIY smart car builds.
Key Features
- Ackermann steering geometry with front-wheel steering and rear-wheel drive; similar to professional RC racing cars
- Single rear motor with die-cast aluminum fixing piece for secure motor-to-transmission engagement
- Two flanged bearings on the transmission shaft for smooth, flexible rotation
- Two acrylic top plates for mounting mainboard, motor driver, and battery
- Shipped as loose pieces; requires self-assembly upon receipt
- No waterproofing; not suitable for use in water or damp environments
