Hiwonder ArmPi Pro Raspberry Pi 5 ROS Robotic Arm Developer Kit with 4WD Mecanum Wheel Chassis Open Source Robot Car

The Hiwonder ArmPi Pro is an advanced open-source robotic car powered by the Raspberry Pi 5, combining a 6DOF vision-guided robotic arm with a 4WD mecanum wheel chassis. This developer kit is ideal for students, educators, and makers looking to explore ROS, computer vision, and autonomous navigation.

Six-DOF vision robotic arm

Featuring a 170-degree wide-angle camera, the ArmPi Pro uses OpenCV for real-time image processing. Coupled with inverse kinematics algorithms, it performs advanced tasks such as colour recognition, face detection, and tag identification.

Omnidirectional mecanum wheel movement

Driven by four high-performance encoder geared motors and four omnidirectional mecanum wheels, the chassis achieves full 360-degree movement. This allows the robot to navigate complex paths and execute versatile movement modes.

First-person view HD transmission

The robot transmits a first-person view to the app interface using WLAN or direct Wi-Fi connection. This high-definition feed allows users to identify colours, locate label codes, and manage intelligent sorting or palletising.

Vision-guided line following

The ArmPi Pro can follow lines autonomously by detecting the target colour selected in the mobile app. It combines this navigation with its robotic arm to transport specific blocks to designated destinations.

Built-in inverse kinematics algorithms

Built-in inverse kinematics algorithms decompose the robotic arm's servo motion control for precise and agile tracking. This mathematical model enables the arm to calculate exact coordinates for grabbing and manipulating objects.

AI target tracking and sorting

Utilising OpenCV as its core image processing library, the FPV camera recognises and locates target blocks. This enables automated AI games, including colour sorting, target tracking, and active line following.
