Build a Working Delta Robot: Inverse Kinematics in Motion with Arduino

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

Three synchronized MG996R servo motors drive a lightweight parallel arm mechanism — a true delta robot. You’ll write the code that reads an XY coordinate and instantly calculates the required joint angles using inverse kinematics. The robot’s platform then glides to that exact point, opening doors to high-speed pick-and-place, drawing, or sorting. It’s a hands-on dive into the math that powers industrial parallel robots, packaged into a 6‑hour build you can complete at home.

What You'll Build

By the final calibration, you’ll have a functional delta robot with a working envelope of roughly 20 cm × 20 cm. Use it to draw precise circles and polygons, sort colored caps by position, or experiment with automated pick-and-place. The inverse kinematics algorithm runs in real time on an Arduino Uno, translating simple XY inputs from a serial monitor or pre‑programmed trajectories into fluid servo motion. The mechanical precision of M3 ball linkages and the low‑jitter PCA9685 driver ensure repeatable movements every time.

What You'll Learn

• Derive and implement inverse kinematics for a parallel 3‑DOF delta mechanism
• Calibrate high-torque MG996R servos and drive them via an I²C PCA9685 PWM controller
• Assemble and align ball‑joint linkages to eliminate mechanical play
• Program real‑time motion control, coordinate transforms, and trajectory planning in Arduino

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11–12 students exploring kinematics in physics, B.Tech ECE/EEE/Mechanical engineering sophomores tackling motion control, and ATL Tinkering Lab teams building robots for Smart India Hackathon challenges. It’s equally at home in IIT, NIT, VIT, and BITS Pilani robotics clubs, where understanding inverse kinematics sets apart a cool project from a truly insightful one. If you already know basic Arduino programming and can solder, this kit moves you straight into professional‑grade motion control.
