Desktop SCARA Robot Arm
4-axis SCARA arm with ESP32 GCode controller — the same toolchain as our Delta robot, with a larger reach.
A compact 4-axis SCARA arm for pick-and-place, drawing, dispensing and teaching. ESP32 controller with open GCode firmware, closed-loop steppers on the shoulder and elbow, and interchangeable end effectors.
What you get
- SCARA arm (pre-assembled and calibrated)
- ESP32-S3 controller in enclosure (firmware pre-flashed)
- 24 V 120 W power adapter (US/EU/UK/AU plugs)
- Two-finger servo gripper
- USB-C cable, emergency-stop button
- Desk mounting plate + M5 hardware
Where it fits
A delta robot is fast over a small circle; a SCARA covers a wider, flat working area with better stiffness in the horizontal plane. That makes this arm a good match for sorting parts across a whole desk, pen plotting, glue dispensing and teaching kinematics — and it speaks the same GCode dialect as our Delta robot, so programs and vision code carry over.
What's inside
- Shoulder and elbow — NEMA17 closed-loop steppers with 20:1 harmonic-style reducers. Encoders catch missed steps and correct them.
- Z axis — lead-screw with 100 mm travel and a homing switch.
- Wrist (R axis) — ±180° rotation for orienting parts.
- Controller — ESP32 with pre-flashed GCode firmware, USB serial at 115200 baud, plus Wi-Fi for the optional web jog panel.
Software
- Send GCode from any serial terminal, or use the Python helper library.
- Inverse kinematics run on the controller; you command X/Y/Z/R in millimetres and degrees.
- The Education Bundle includes lesson plans covering forward/inverse kinematics, trajectory planning and simple vision-guided picking.

FAQ
Can I reuse my Delta robot programs?
Mostly. Both robots use the same GCode dialect and serial protocol. Coordinates are in millimetres in each robot's own frame, so you will need to re-teach pick positions, but the host software and vision pipeline work unchanged.
Delta or SCARA — which should I buy?
Choose the Delta for fast pick-and-place over a small conveyor area. Choose the SCARA for a larger flat workspace, drawing/dispensing, or if you need wrist rotation.
Is it safe to use in a classroom?
It is a low-power desktop arm with current-limited motors and an emergency-stop button, but it is still a moving machine: supervise students and keep hands out of the working area while it runs.
Do I need to calibrate it?
It ships calibrated. Homing runs automatically on power-up; a one-minute re-calibration routine is included if you remount the arm.
Warranty
12-month limited warranty covering manufacturing defects. Consumables (suction cups, belts) and damage from modification are excluded.
