Arduino Inverse Kinematics Arm Kit — Build a 2-DOF Servo Arm That Solves IK Equations

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

What if your robotic arm could calculate exactly how to bend its joints to reach any point on a surface? This kit puts the power of inverse kinematics into your hands. You'll assemble a 2-DOF arm driven by three SG90 servos (one for the gripper), then program Arduino Nano to solve coordinate-to-angle transformations in real time. Move the end effector to the target position with precision — no trial-and-error guessing.

What You'll Build

A functional 2-DOF robotic arm that accepts XY coordinates via push buttons, calculates joint angles using inverse kinematics, and moves the gripper to the exact location. The 0.96-inch OLED displays the target position and computed angles in real time. Perfect for demonstrating mathematical robotics concepts in classrooms or hackathons.

What You'll Learn

• Implement inverse kinematics equations in C++ on Arduino Nano
• Control multiple servo motors for synchronized joint movement
• Read digital inputs from push buttons to set target coordinates
• Display sensor and computed data on an OLED screen via I2C
