The 4WD Smart Robot Car Chassis is a durable, versatile, and easy-to-assemble platform designed for robotics projects, educational engineering builds, and DIY automation systems. Made from high-quality transparent acrylic, this chassis provides a strong and stable base for building line follower robots, obstacle-avoiding robots, RC cars, wireless bots, sumo robots, autonomous navigation systems, and more. Compatible with Arduino, Raspberry Pi, Motor Driver Shields, and most microcontroller platforms, it offers flexibility and expandability for beginners and advanced users.

This 4-wheel drive (4WD) kit includes DC geared motors, rubber-tired wheels, encoder wheels, mounting hardware, and dual platforms for component installation. The kit is supplied disassembled, allowing complete hands-on assembly experience for learners and hobbyists.
