The Complete Robotic Arm 6DOF is an all-metal robotic arm kit with six degrees of freedom — it moves much like a human arm, with base rotation, shoulder, elbow, and wrist movement plus a gripper. Each axis is driven by its own servo motor (six in total), so the arm can rotate, reach, lift, and grip objects. Built from aluminum plates for strength and stability, it is a popular platform for STEM education, robotics training, and DIY automation projects, and it can be controlled from an Arduino for hands-on learning in motion, programming, and mechanical design.
Key Features
- Six degrees of freedom (6DOF) — base rotation, shoulder, elbow, wrist, and gripper movement.
- Six servo motors — the arm ships with a full set of MG996R metal-gear servo for stable output; it can also be fitted with high-torque digital servos.
- Aluminum construction — all bracket parts are made from 2 mm aluminum plate, which improves the stability of the manipulator.
- Ball bearings at the joints — imported cup bearings make each joint move smoothly and stay accurately centered.
- Disc-shaped base — allows smoother, more flexible left-and-right rotation.
- Assembly video included — a build/usage video is provided on the product page.
What You Can Do With It / Common Uses
- Learn and teach robotics and automation concepts (STEM education).
- Build pick-and-place and simple handling demonstrations.
- Practise servo control and programming with an Arduino.
- Use it as a maker / DIY robotics platform.
Control & Compatibility
- Arduino: the six servos are driven with standard PWM control signals, which makes the arm a good match for Arduino-based projects.
- Raspberry Pi and other controllers: also usable, but a Raspberry Pi does not drive multiple servos reliably on its own — an external servo/PWM driver board (for example a PCA9685) and a suitable power supply are recommended.
- A separate controller board, servo driver, and power supply are needed to run the arm (sold separately).
Frequently Asked Questions
How many motors does this robotic arm use?
Six. The kit includes a full set of six servo motors — one for each degree of freedom.
What is "6DOF"?
6DOF means six degrees of freedom — six independent movements (such as base rotation, shoulder, elbow, wrist, and gripping) that let the arm move in a human-like way.
Is it suitable for beginners and students?
Yes. It is widely used for college teaching, robotics training, and DIY projects, and an assembly video is provided.
Can I control it with an Arduino?
Yes. The servos use standard PWM signals, so the arm works well with Arduino. For a Raspberry Pi, an external servo/PWM driver board is recommended.
Does it come assembled?
It is supplied as a kit with the structural parts and servos; assembly is required (a video guide is provided).
