Hiwonder MasterPi AI Vision Robot Arm with Mecanum Wheels Car — Raspberry Pi 5 - 8GB

The Hiwonder MasterPi is an open-source AI vision robot car powered by Raspberry Pi, featuring a five-degree-of-freedom robotic arm and a Mecanum-wheel chassis. It is designed for students, educators, and hobbyists looking to explore Python programming, OpenCV machine vision, and autonomous driving. This robust kit brings hands-on robotics to life with real-time FPV and intelligent colour-sorting capabilities.

Five-axis robotic arm with HD camera

The chassis is equipped with a five-degree-of-freedom robotic arm capable of grabbing and carrying target objects. An HD wide-angle camera is mounted at the end of the arm, enabling intelligent eye-following operations.

Omnidirectional Mecanum wheel chassis

Four omnidirectional Mecanum wheels allow the robot to move 360 degrees, including sideways, diagonally, and rotational movements. This versatile chassis enables the vehicle to navigate complex routes with ease.

OpenCV machine vision and FPV

Utilising OpenCV for advanced image processing, the robot uses its real-time First Person View to locate and identify target blocks. This enables autonomous tasks such as colour sorting, colour recognition, and line following.

Graphical PC software control

The included graphical PC software allows users to control the rotation of the servos by dragging sliders without writing code. It also provides an interface to edit and configure custom robot action groups.

Visual colour threshold adjustment

The robot comes with a dedicated threshold adjustment tool that lets users visually fine-tune the LAB colour space. This ensures reliable object and line recognition under varying lighting conditions.

Dual-platform mobile app control

The WonderPi application is compatible with both Android and iOS devices, allowing quick switching between different game modes. Users can remotely control the robot and experience various AI games directly from their smartphone.

Raspberry Pi processing power

Powered by a Raspberry Pi 4B or 5 controller, this platform supports advanced motion control and machine vision projects. It is an ideal open-source hardware setup for learning Python and OpenCV.

Intuitive aluminium alloy build

The robot features a hard aluminium alloy body that protects the core control board from shocks and supports heavier loads. It is designed for quick assembly with step-by-step instructions to get your project running quickly.

High-torque metal gear servos

The robot utilises high-performance LDX-218 digital servos featuring full metal gears, dual ball bearings, and 17kg of torque. These servos offer a 180-degree control angle for precise and durable robotic arm manipulation.
