Keyestudio 4WD Mechanical Arm Robot Smart Car for Arduino Robot /Support Android &IOS

The Keyestudio 4WD Mechanical Arm Robot Smart Car is a versatile 3-in-1 learning kit designed for students, educators, and makers wanting to master robotics and Arduino programming. This solder-free kit combines a mobile four-wheel-drive platform with a flexible metal mechanical arm, allowing users to build, programme, and control their own robotic vehicle. It is ideal for anyone looking to transition from basic C-language coding to advanced mobile manipulation.

Three-in-one learning platform

This versatile kit functions as a standalone smart car, a stationary mechanical arm, or a combined mobile robotic arm vehicle. It provides a practical, hands-on way to learn how to coordinate mobile bases with robotic manipulators.

Solder-free assembly and robust build

Designed for easy construction with no soldering required, the kit features a high-tenacity car baseplate and a durable metal mechanical arm. This ensures a sturdy, resilient build that can withstand regular classroom or workshop use.

Advanced motor drive and power

Powered by a TB6612 motor driver, the system operates on an input voltage of 7-12V and delivers a maximum output current of 3A. The four motors run at 63 rpm at 5V, providing reliable torque and movement for the 4WD chassis.

Smart navigation and obstacle avoidance

Equipped with an ultrasonic sensor, the car detects obstacles from 2cm to 400cm away within a 15-degree sensing angle. This enables automated features such as obstacle avoidance, line tracking, object following, and anti-fall protection.

Dual-system Bluetooth App control

You can control the robot wirelessly from 20 to 50 metres away using the dedicated Bluetooth application, which fully supports both Android and iOS systems. It also includes an infrared receiver for traditional IR remote control.

Expandable motor driver shield

The included motor driver shield allows you to easily expand the system by connecting additional sensors and modules. This high-extension capability makes the platform highly adaptable for custom hobbyist projects and advanced school curricula.

C-language programming and tutorials

Learn basic programming using C-language code with the downloadable online tutorials, libraries, and sample code for code KS0523. This structured learning path helps students grasp fundamental coding concepts while interacting with physical hardware.
