Build Your First Cartesian Robot: Gantry XY Motion Kit with Arduino and Stepper Motors

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

Send X,Y coordinates from your computer and watch the gantry carriage move to precise positions. This kit introduces the fundamental concept behind 3D printers, CNC routers, and pick-and-place machines — Cartesian motion — in a hands-on, beginner-friendly way. You’ll turn raw serial commands into synchronized stepper motor moves, laying the foundation for more advanced robotics projects.

What You'll Build

A working benchtop gantry system that responds to serial inputs. Two NEMA 17 steppers drive a carriage along perpendicular axes using GT2 belts and pulleys. An OLED displays real-time coordinates, and you'll plot simple paths by typing commands like “X100 Y50” into the serial monitor. It’s a tangible demonstration of how machines translate digital position data into physical motion.

What You'll Learn

• Interface stepper motors with Arduino Uno R3 using A4988 drivers and a CNC Shield V3
• Convert X,Y coordinates into synchronized step and direction signals for dual-axis control
• Send and parse serial communication strings from a PC to command hardware in real time
• Display position data on a 0.96in OLED screen for immediate visual feedback
