6 DOF Robot Arm
Metal alloy mechanical arm with 6 Degree of Freedom. The kit is delivered in a simple carton. The subassemblies are packaged in separate bags. The structural elements of the robotic arm are made by stamping aluminum plate. To give a better appearance and deburr the edges, the pieces are sandblasted. Black anodising (visible on the assembly instructions) has been abandoned. Positive point of this kit, we find very easily spare parts. Most structural elements, servo motors MG996R, flanged base, clamp (or claw) are standard elements that are found very often our store.
The 6DOF All-Metal Robotic Arm Kit with Servos is a versatile and durable robotic manipulator, widely used for college teaching, robotics training, and DIY projects. Built from high-quality aluminum plates, the arm offers excellent stability, making it ideal for demonstrating robotic concepts, automation experiments, and hobbyist applications.
The disc-shaped chassis design ensures smooth and flexible left-right rotation, while the six included servo motors power a wide range of movements such as lifting, gripping, and rotating.
Whether you are an educator, student, or robotics enthusiast, this robotic arm provides a solid platform for learning robotics, kinematics, and automation control.
