Product Introduction

AI Vision Robot Arm Meets 360° Mecanum Car

MasterPi 5DOF robot arm eye-in-hand camera

High-Performance Vision Robot Arm

5DOF Robot Arm with Eye-in-Hand Camera

MasterPi's body is equipped with a 5-degree-of-freedom robotic arm that can easily grab and carry target items. The end of the MasterPi robotic arm is equipped with a HD wide-angle camera, which can perform eye-following operation — the camera moves with the arm, providing a first-person perspective that enables precise object localization and automated item picking.

By leveraging the OpenCV library, MasterPi can effectively recognize and locate target objects to implement AI applications such as color sorting, target tracking, and line following. MasterPi utilizes high-performance LDX-218 servos with metal gear, metal servo horn, providing robust force and high accuracy performance. The protective body structure can bear bigger loads and shields the control board from shock.

Color sorting — identify and sort objects by color using OpenCV
Target tracking — PID-controlled arm follows detected targets
Intelligent transport — pick up, carry, and deliver items autonomously
Line following — detect and follow color lines on the ground

MasterPi 360 degree mecanum wheel movement

360° Omnidirectional Mecanum Movement

4-Wheel Mecanum Chassis — Bold to Challenge Any Route

With 4 omnidirectional Mecanum wheels, MasterPi can realize 360° omnidirectional movement. Different movement modes including forward, horizontal, diagonal, and rotation make it bold to challenge various complicated routes with exceptional performance. Loaded with a 120° wide-angle camera, combined with the Mecanum chassis, the visual range reaches 360°.

Hiwonder JetAuto's high-precision pendulum suspension structure balances the force exerted on all four wheels, enabling good adaptability to uneven surfaces. The Mecanum wheel chassis is controlled via the WonderPi app or through Python code, allowing both beginner-friendly app control and professional programmatic operation.

MasterPi graphical PC software servo control

Graphical PC Software & App Control

No-Code Control, Action Editing & Color Calibration

With the graphical PC software, you can control the rotation of the robot servo by dragging sliders without writing any code, and can edit and save the robot action group for later playback. MasterPi is equipped with a LAB color space threshold calibration tool that allows you to visually fine-tune color recognition parameters with precision.

WonderPi APP supports Android and iOS. Switch game modes easily and quickly to experience various AI games. MasterPi is easy to assemble with the provided instructions — you can enjoy the building process while learning about the robot's mechanical and electronic structure. Detailed course materials include open-source Python code and video lessons by real instructors.

Frequently Asked Questions

MasterPi FAQ

Does the Raspberry Pi 4B (4GB) come included in this variant?

Yes. This variant includes the Raspberry Pi 4B with 4GB RAM. The pre-installed system image and all required Python open-source code are provided, so you can begin programming and running AI experiments immediately after assembly.

How does the eye-in-hand camera work on MasterPi?

The HD wide-angle camera is mounted at the very tip of the 5DOF robotic arm. As the arm moves, the camera moves with it, providing a first-person view from the arm's perspective. OpenCV processes the live camera feed to identify and localize target objects by color, and inverse kinematics calculates the exact joint angles needed for the arm to reach and grasp the target.

Can I control MasterPi without writing any code?

Yes. The graphical PC software lets you control all servo positions by dragging sliders — no coding required. You can also edit and save complete action sequences. The WonderPi app on iOS/Android provides full motion, grip, and FPV control over WLAN or Wi-Fi direct connection.

What AI vision tasks can MasterPi perform?

MasterPi supports: face tracking with PID-controlled camera follow, color tracking and sorting (pick up objects by color with the arm), QR code recognition, gesture recognition (hand gesture to robot command), object recognition, and visual line following. It uses OpenCV with a LAB color space calibration tool for precise color threshold adjustment.

What tutorials and learning resources are included?

MasterPi includes detailed tutorials covering motion control, Mecanum wheel control, AI vision tasks, OpenCV image processing, PC software programming, and app usage. All tutorials come with open-source Python code and video lessons by real instructors — covering everything from getting started to advanced AI game development.
