Collection: All Robot Arm Kits

Overview

Our complete catalog of DIY robot arm kits spans from entry-level 1-DOF grippers at $23 to professional-grade 7-DOF industrial manipulators at $420. Every kit uses CNC-machined aluminum alloy construction and real servo or stepper motors — no plastic, no toy-grade components. Whether you are a first-time builder or an experienced engineer, there is a kit here for your skill level and budget.

Choosing the Right DIY Robot Arm Kit

The most important decision when selecting a robot arm kit is the number of degrees of freedom (DOF). A 1-DOF gripper opens and closes — ideal for a first project or as an end effector add-on. A 4-DOF arm gives you base rotation, shoulder, elbow, and wrist movement. A 6-DOF arm adds full spatial control, matching the workspace of industrial robots. A 7-DOF arm includes a redundant joint for obstacle avoidance. Match your DOF to your project complexity and your budget.

What Every Kit Includes

• Metal frame: Anodized aluminum alloy brackets and channels, pre-drilled
• Motors: MG996R high-torque servos (servo kits) or NEMA steppers (industrial kits)
• Hardware: All screws, standoffs, and fasteners included
• Sample code: Arduino sketches for basic joint control and sweep sequences
