Overview
The Yahboom Mini Wheeled Robot Car robot car chassis kit uses a compact aluminum-alloy, single-layer chassis designed for robot car races with field size limits. With a chassis width of 14.2 cm (less than 15 cm) and an overall size under 25 cm in length, it is suitable for small-format DIY mobile robot platforms. Multiple mounting holes are reserved to support expansion boards, sensors, camera PTZ assemblies, and communication devices.
Key Features
- All aluminum alloy frame; workmanship: silver, oxide sandblasted
- Reserved installation holes to meet personalized expansion needs
- Four-wheel drive chassis structure; platform notes: two-wheel drive/four-wheel drive optional
- Uses 310 encoder reduction motors; encoder type: 13-wire AB phase Hall encoder (3.3–5V)
- 48 mm rubber tires; 310 motor shaft uses a “flower shaft” design to increase friction and reduce tire detachment risk
- 3D model files of the chassis are provided (as stated by the supplier)

Details
A compact 4WD chassis platform sized for small-format robot car races, with room to mount controllers, sensors, and add-ons.
Optional vision modules can be mounted on an adjustable bracket for AI recognition tasks and interactive projects.
Reserved mounting points make it easy to add tracking sensors, an IMU, or a 2DOF PTZ for camera or sensor aiming.
The 48 mm tires pair with a flower-shaft motor design to help improve grip and reduce the chance of tire detachment.
Multiple slots and threaded holes support flexible layouts for development boards, motor brackets, and common module mounts.
Choose from tracking, distance, IMU, and interaction modules to build the robot car features your project needs.
Control options include an IR remote or a 2.4G wireless controller for hands-on driving and testing.
The mini car chassis uses a 195 × 106 mm aluminum-alloy plate (2 mm thick) with slotted mounting points and M2/M3 threaded holes for easy assembly.
The 4-channel encoder motor driver module supports 5–12V input, 6.5A motor drive, and I2C/serial plus Type‑C connections for robot builds.
