Product Description
Hiwonder's NexArm ROS Robotic Arm is an all-in-one experimental platform purpose-built for advanced ROS education and embodied AI research. Featuring an advanced modular architecture, it natively fuses multimodal large models, OpenClaw agents, ACT, VLA, machine vision, and inverse kinematics into a complete validation loop spanning foundational concepts to high-level embodied algorithms.
Its NVIDIA/Raspberry Pi + ESP32 dual-controller setup powers a high-performance hardware suite consisting of magnetic encoder bus servos, a parallel-rail gripper, a 3D depth camera, and an AI voice module. Deep integration of multimodal AI and OpenClaw agents drives precise 3D depth perception and multi-dimensional sorting. It fully satisfies full-stack development demands, spanning environmental sensing to real-world physical manipulation.
Large AI Model & OpenClaw
Fusing the OpenClaw agent with multimodal AI models across speech, language, and vision, the NexArm ROS robotic arm executes complex remote tasks like visual scene understanding, dynamic object tracking, and data aggregation and analysis.
Versatile Controller Compatibility
The NexArm ROS robotic arm controller assembly supports Raspberry Pi and high-performance Jetson controllers. Equipped with a multi-functional expansion board and rich ports, it seamlessly accelerates development and hardware expansion.
3D Spatial Recognition & Grasping
An integrated 3D structured light depth camera fuses RGB and depth data, utilizing advanced vision algorithms to power object tracking, detection, and facial recognition for precise 3D spatial perception and grasping.
Inverse Kinematics & Eye-Hand Coordination
Powered by an in-house, high-performance inverse kinematics algorithm, NexArm reaches any coordinate within its workspace, driving advanced AI projects like grasping, sorting, and transporting.
Dual-Output-Shaft Magnetic Encoder Bus Servo
A dual-shaft design with the main shaft for power output and the secondary shaft for support, delivering greater operating stability.
Parallel-Rail Gripper
Silicone gripper pads and stainless-steel transmission components ensure a secure grip and improved durability.
Aerospace-Grade Industrial Bearing Base
An industrial bearing base supports 270° joint rotation and positioning, while the aerospace-grade structure reduces Z-axis wobble.
OLED Display Design
Equipped with an OLED screen that displays real-time data of this open-source robotic arm.
