Overview
The Yahboom MSPM0 Smart Robot Car Aluminum Alloy chassis kit is a wheeled mobile development platform designed for electronic design competitions, educational training, and maker projects. It uses an all-aluminum alloy, two-layer chassis structure and supports two-wheel drive (2WD) or four-wheel drive (4WD) configurations with high-precision Hall encoder reduction motors. The kit is compatible with the MSPM0 main control board and supports fast integration of motors, drivers, and common robot sensors.
Key Features
- All-aluminum alloy frame; oxidized sandblasting process
- 2WD / 4WD chassis options (length and width are the same; different versions mainly differ in height)
- Multiple reserved installation holes for flexible expansion and accessory mounting
- 65 mm high-friction tires; D-type shaft coupling design to reduce the risk of tires coming loose
- Supports high-precision Hall encoder reduction motors (L-type 520 encoder motor)
- Compatible with MSPM0 main control board and MSPM0 robot expansion board
- Expansion support for vision modules (K210 / K230), line tracking modules (3/4/8-channel), MPU6050 or 10-axis IMU modules, and 2DOF electric PTZ mounting
