Cherokey: 4WD Mobile Robot for Arduino

Cherokey 4WD Mobile Robot Platform is a rugged robotic vehicle chassis designed for rapid prototyping of autonomous and remote‑controlled robots. The aluminum‑alloy mobile robotics platform integrates a dual‑channel L298P motor driver capable of controlling two 6–12V DC motors at up to 2A, eliminating the need for an external motor driver board. Mounting holes support popular controllers such as DFRduino UNO R3 - Arduino Compatible, Mega2560 (Arduino compatible microcontroller board), and Romeo V2 - a Robot Control Board with Motor Driver (Compatible with Arduino). Designed for robotics experimentation, the four‑wheel‑drive rover platform offers strong off‑road mobility across grass, gravel, sand, and inclined surfaces while supporting rapid electronics integration.

Integrated Motor Control and Wireless Expansion

The robotic vehicle chassis integrates an onboard L298P dual H‑bridge motor driver capable of driving two DC motors within a 6–12V range and delivering up to 2A current. Built‑in sockets support wireless communication modules such as XBee and APC220, allowing immediate development of remote‑controlled or autonomous robotics systems without installing additional driver shields. This integrated electronics layout simplifies wiring and reduces system complexity when building mobile robots powered by Arduino controllers or other compatible development boards.

Expandable Prototyping and Servo Mounting Area

The expansion plate significantly increases the usable surface area of this four‑wheel robotic chassis, enabling installation of sensors, actuators, and custom circuitry. Dedicated servo mounting positions support either 9g micro servos or standard‑size servos, ideal for robotic arms, ultrasonic range modules, or infrared obstacle sensors. Double‑sided prototyping pads located at the center allow soldering of both DIP and SMD components, enabling quick addition of custom circuits, sensor interfaces, or robotics control extensions directly on the mobile robot platform.

Durable Aluminum Structure for Outdoor Robotics

The structural frame uses high‑strength aluminum alloy components that provide durability while maintaining lightweight mobility. Combined with four geared motors and rubber wheels, this off‑road robotics chassis supports stable movement across uneven terrain including grass, gravel, sand, and sloped surfaces. The reinforced structure and wide wheelbase make the four‑wheel‑drive robot base suitable for robotics competitions, outdoor experiments, and research prototypes requiring reliable mobility and mechanical stability.
