Arduino Robot Arms

Overview

Every Arduino robot arm in our catalog is designed for direct control from an Arduino Uno, Mega, or Nano — no external motor driver required for servo-based kits. Plug servo signal wires into PWM pins, upload the included sketch, and the arm moves on first power-up. Seven of our ten active kits explicitly support Arduino as their primary control platform.

Programming an Arduino Robot Arm

Servo control from Arduino uses the built-in Servo.h library. Each servo occupies one PWM-capable digital pin and is controlled with a single servo.write(angle) command where angle is 0–180. For a 6-DOF arm with 6 servos, you need 6 PWM pins — the Arduino Mega or a PCA9685 I2C servo driver board is recommended for arms with 5 or more joints. All kits include sample Arduino sketches covering basic joint sweep, sequential position sequences, and (for applicable variants) PS2 wireless controller parsing.

Compatible Boards Arduino Uno, Mega, Nano; ESP32; Raspberry Pi
Library Servo.h (servo kits), AccelStepper (stepper kits)
PWM Pins Required 1 per DOF (3–7 pins)
Code Included Yes — Arduino .ino sketches with all kits
IDE Arduino IDE 2.x compatible
DOF Range 1 – 7 DOF

Quick Start: 6-DOF Arm Code Pattern

// 6-DOF Arduino Robot Arm — Quick Start #include <Servo.h> Servo j1, j2, j3, j4, j5, j6; void setup() { j1.attach(3); j2.attach(5); j3.attach(6); j4.attach(9); j5.attach(10); j6.attach(11); } void loop() { j1.write(90); // center all joints delay(1000); }
