Smart Robot Car Small 2WD Motor Chassis

The Smart Robot Car Small 2WD Motor Chassis is a lightweight, modular two-wheel-drive platform designed for DIY robotics, educational projects, and rapid prototyping. It serves as an ideal mechanical base for building autonomous or remote-controlled vehicles using microcontrollers such as Arduino, Raspberry Pi, or ESP32. Key Features Easy Customization: Pre-drilled laser-cut acrylic chassis with mounting holes for popular controllers, motor drivers, battery packs, and sensors. Differential Steering: Dual independent DC gear motors allow for forward/reverse motion, precise turns, and 360° pivot maneuvers. High Traction: Includes 65 mm rubber tires designed to provide grip on various surfaces. Speed Encoders: Features encoder code wheels for optical speed/distance tracking and odometry calculations.
