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.

DOF Range 1 DOF (gripper) to 7 DOF (industrial)
Motor Types Servo (MG996R, SG90, A0090) and NEMA Stepper
Material CNC-machined aluminum alloy
Price Range $23 – $420
Compatibility Arduino, Raspberry Pi, ESP32

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
  • Assembly guide: Step-by-step instructions with diagrams
  • Variants available: With or without controller board, with or without gripper
Power Supply Note

Servo-based kits require a dedicated 5V–7.4V supply rated at 2A minimum — do not power multiple servos from the Arduino 5V pin. Stepper kits require 12V–24V at 3A+.
