Hiwonder NexArm Open-Source ROS Robotic Arm VLA Embodied AI Kit with NVIDIA/Raspberry Pi & ESP32 Dual-Controller Design, Multimodal Large AI Models & OpenClaw

The Hiwonder NexArm is an advanced, open-source ROS robotic arm kit designed for cutting-edge embodied AI research and university-level robotics education. Featuring a dual-controller architecture and multimodal large model integration, it is the ideal platform for South African educators, students, and advanced makers looking to master physical manipulation and machine vision.

Dual-controller embodied AI platform

This kit features an NVIDIA/Raspberry Pi and ESP32 dual-controller architecture to support advanced ROS education and embodied AI research. It integrates multimodal large models, OpenClaw agents, and machine vision to bridge the gap between high-level algorithms and physical manipulation.

Modular sandbox baseplate expansion

The modular metal sandbox baseplate allows developers to efficiently replicate complex physical interaction scenarios such as smart warehousing. It seamlessly integrates with expandable peripherals including electric sliding rails and suspended chassis systems.

Versatile controller compatibility

The controller assembly supports high-performance Jetson controllers and Raspberry Pi. Equipped with a multi-functional expansion board and rich ports, it accelerates hardware expansion and custom development.

3D spatial perception and grasping

An integrated 3D structured light depth camera fuses RGB and depth data to power object tracking, detection, and facial recognition. This enables highly precise spatial awareness for automated sorting and manipulation tasks.

Advanced inverse kinematics

Powered by an in-house, high-performance inverse kinematics algorithm, the robotic arm can reach any coordinate within its workspace. This coordinate-based control drives complex AI tasks like automated grasping, sorting, and transporting.

Magnetic encoder bus servos

The dual-output-shaft design utilises the main shaft for power output and the secondary shaft for structural support. This configuration delivers greater operating stability and precise joint control.

Durable parallel-rail gripper

Equipped with silicone gripper pads and stainless-steel transmission components, the gripper ensures a secure hold on objects. This robust design improves overall durability during repetitive physical manipulation tasks.

Aerospace-grade industrial bearing base

This industrial bearing base supports 270-degree joint rotation and precise positioning. The aerospace-grade structure significantly reduces Z-axis wobble during high-speed movements.

Real-time OLED display

An integrated OLED screen displays real-time system data directly on the robotic arm. This allows developers to monitor status and debug operations without needing an external monitor.
