Cartesian Pick and Place Robot
Arduino-Powered Cartesian Pick & Place Robot Kit – Build a 3-Axis Gantry with G-Code Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a precise Cartesian pick and place robot that automates small object handling using standard G-code commands. This kit layers stepper motor control, linear motion assembly, and serial communication into a single cohesive project — ideal for an engineering capstone, a hackathon prototype, or serious home lab automation. You’ll assemble a rigid 3-axis gantry, wire a CNC shield with A4988 drivers, and upload firmware that parses G0/G1 sequences to move the gantry and actuate the servo gripper with repeatable accuracy.
What You'll Build
You’ll construct a desktop Cartesian robot that picks objects from a taught coordinate and places them at a target location. The Arduino Mega reads G-code lines over USB from any serial terminal or sender, translating them into coordinated X, Y, and Z moves. The result is a small-scale pick-and-place cell you can program, iterate, and repurpose for lab automation, PCB handling, or custom manufacturing tasks.
What You'll Learn
- Wire and configure three A4988 stepper drivers on a CNC shield V3 to control NEMA 17 motors with microstepping
- Parse incoming G-code strings on Arduino, extract coordinates, and map them to stepper pulses with acceleration ramping
- Assemble and align linear rails, GT2 belts, and pulleys into a backlash-free 3-axis motion system
- Solder 100 nF decoupling capacitors and prototype board circuitry for noise-free driver operation

Who This Kit Is For
This kit is built for B.Tech ECE/EEE students fabricating a final-year project on automated material handling, participants in Smart India Hackathon building automated warehousing prototypes, and hobbyists who want to explore CNC-like motion without the cost of a full machine. If you’ve outgrown simple Arduino robots and are ready to tackle multi-axis motor control and G-code parsing, this project delivers a real-world challenge.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion offers step‑by‑step diagnostics for wiring, G‑code parsing, and motor tuning. If you need human help, reach out via WhatsApp for direct support.
Is the G‑code compatible with standard CNC sending software?
Yes, it works with any serial G‑code sender (like Universal Gcode Sender) that streams standard G0/G1 commands at 115200 baud. Our companion includes setup instructions for common tools.
Can this pick and place small electronic components like SMD parts?
The included SG90 servo gripper handles lightweight objects up to about 50g, such as small PCBs, nuts, or 3D‑printed parts. For SMD components, you can modify the gripper design or replace it with a vacuum pickup.
What if a linear rail is bent or a stepper driver fails?
If any part arrives with a manufacturing defect, we replace it free within 7 days. Just contact us via WhatsApp or email, and we’ll ship a replacement from our Bengaluru warehouse.
