SMART ROBOT CAR CHASSIS KIT / 4 WHEELS
Construct high-traction autonomous rovers, obstacle-avoiding cars, and heavy-payload robots using this complete 4WD Robot Chassis Kit.
Navigating rougher indoor surfaces requires more pushing torque and stability than standard two-wheel drive chassis can deliver. However, this expandable 4WD Smart Robot Car Chassis Kit provides a heavy-duty, double-decker mechanical platform for complex physical computing. It combines four independent DC gear motors with high-traction rubber wheels to deliver smooth four-wheel drive performance. Consequently, you can carry larger payloads and complex sensor arrays without stalling your motors.
Key Features:
Double-Layer Modular Acrylic Chassis Plates: It features two laser-cut acrylic plates connected by brass standoffs. Because of this stacked dual-level layout, organizing battery packs, drivers, and microcontrollers is exceptionally clean.
Four High-Torque TT DC Gear Motors: The kit includes four reliable 1:48 gear ratio TT motors paired with rubber tires. Therefore, your robot achieves balanced torque and superior traction across various indoor surfaces.
Integrated Speed Encoder Discs: It features slotted optical tachometer discs for each individual motor shaft. Furthermore, these encoder wheels allow precise closed-loop speed measurement and wheel odometry.
Pre-Drilled Universal Sensor Mounting Slots: It features specialized mounting cutouts for ultrasonic distance sensors and servo motors. Simply bolt your hardware components directly onto the pre-cut acrylic grid.
Why should you choose this 4WD smart robot car chassis kit? Are you designing indoor mapping rovers, building Wi-Fi video streaming tanks, or teaching advanced STEM robotics? Because of its dual-layer structure, you get twice the mounting area compared to single-plate platforms. Moreover, driving four independent wheels prevents high-centered slipping on uneven thresholds. Furthermore, it offers long-term mechanical strength for engineering students, educators, and robotics hobbyists alike. Therefore, it is an ideal hardware platform for advanced mobile computing projects. Simply assemble the included hardware to bring your four-wheel drive robot to life today.
