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

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.

The MSPM0 development board dimensions and 310 encoder DC motor sizing details help with planning fitment and wiring in the mini wheeled robot build.

The L-shaped metal motor bracket uses a 3 mm thick plate with multiple mounting holes for fixing a 310 encoder motor.

The mini wheeled robot specs outline the expansion board layout and key sizing details, including a 48mm tire diameter and 27.5mm tire width.

The Yahboom mini wheeled robot chassis is shown as an exploded assembly with four wheels, a motor, and mounting brackets for DIY builds.

The Yahboom BT remote control app for iOS and Android provides a main control screen plus sensor status and mode selection interfaces.

A detailed course outline helps guide setup, programming practice, and module experiments for the mini wheeled robot.

Yahboom’s online tutorial resources group the mini chassis files and related motor drive and development guides for easier setup and learning.

STM32 development tutorials and documentation provide ready-to-use routines and reference material for getting started with the controller board.

The kit parts list includes an aluminum alloy chassis, 310 encoder motors with 48mm rubber tires, wiring, screws, and optional driver and expansion boards.
