2WD Round Smart Robot Car Chassis Kit – Circular Dual-Deck Acrylic Base with DC Gear Motors & Encoders for Arduino & Raspberry Pi in Pakistan

Overview 

The 2WD Round Smart Robot Car Chassis is a versatile, circular robotic platform designed specifically for university mechatronics projects, line-following competitions, and maze-solving autonomous bots. Unlike rectangular chassis platforms that can catch their corners on walls or obstacles while turning, the symmetrical round shape allows the robot to rotate 360^\circ within its own footprint. Constructed from durable, laser-cut acrylic plates with pre-drilled mounting slots, it easily integrates with Arduino, ESP32, Raspberry Pi, sensors, and motor drivers.

Why Robotics Developers Prefer the Round Frame 

• Zero-Radius Turning Circle: The circular profile prevents corner snagging during sharp pivots, making it ideal for micro-mouse mazes, sumo-bot arenas, and tight indoor environments.

• Dual-Layer Modular Stacking: Comes with spacer standoffs to create a double-deck arrangement, allowing you to mount your battery pack on the lower deck and logic boards/drivers on the upper deck for clean wire organization.

• Built-in Optical Speed Encoders: Includes slotted code wheels on the motor shafts so you can attach photo-interrupter sensors to measure RPM, calculate distance traveled, and implement closed-loop PID speed control.
