Six-axis Robotic Arm (Based on a Raspberry Pi) With Flat Base

Six-axis Robotic Arm (Based on a Raspberry Pi) with Flat Base delivers a compact yet capable robotics development platform designed for research, education, and embedded automation experiments. Powered by a Broadcom BCM2711 processor and running Ubuntu/Debian environments, this six‑degree‑of‑freedom robotic manipulator provides a 280mm working radius and onboard computing without requiring a separate PC. Native hardware interfaces including USB, HDMI, and GPIO enable seamless integration with sensors, cameras, and custom peripherals. This intelligent robotics platform supports algorithm development, ROS simulation, machine vision experimentation, and programmable automation within a portable, all‑in‑one system.

Standalone Robotics Platform with Embedded Linux

Built around a Raspberry Pi microprocessor and Ubuntu-based operating system, this robotic manipulation system operates independently without relying on an external computer. The onboard computing environment enables direct deployment of robotics algorithms, ROS-based simulations, and real‑time control tasks. With a 1.5GHz quad‑core CPU and multiple hardware interfaces, the robotic arm controller supports peripherals such as displays, sensors, and cameras while maintaining a compact footprint suitable for laboratories, classrooms, and embedded robotics experimentation.
