Build the mechanism, connect the electronics and turn code into visible movement. This programmable SCARA robotic arm DIY kit combines three stepper motors, two servos and a Wi-Fi-enabled control board in a hands-on project for robotics learners and makers.
The yellow-and-black arm features a claw gripper, articulated links and a vertical guide assembly. Computer control through Wi-Fi or USB, Arduino programming and a Blockly graphical interface give you several ways to explore movement sequences. The illustrated programming interface also includes a Python tab.
This is an unassembled kit. You assemble the parts yourself. Technical documentation is available on request, including STL print files, robotic arm source code, a circuit diagram, an assembly tutorial and host computer source code.

Why This SCARA Robotic Arm
Mechanics you can examine: The exposed linkages, guide rods and gripper let you follow how individual motor movements contribute to the arm's overall motion.
Motor and servo integration: Three stepper motors work alongside two servos, offering a practical project for studying different actuator roles.
Two computer connection routes: Wi-Fi and USB control let you explore the documented connection methods for the supplied controller.
Graphical and code-based learning: Blockly controls shown in the interface cover arm angles, coordinates, vertical movement, wrist angle and gripper commands.
Files for deeper exploration: Request the assembly guide, circuit diagram, STL files and source code to connect the physical build with its software and design.
What Is It For & How It Helps
This kit is for makers, robotics learners and supervised educational projects that involve assembly, electronics and programming. Building the arm gives you a concrete way to connect a mechanical joint, an actuator, a controller connection and a software command.
Use it to explore coordinate movement, gripper sequencing and the relationship between arm geometry and reachable positions. Begin with individual movements, then combine them into a sequence. It is a learning project rather than a ready-to-run appliance, so plan time for assembly, setup and testing.

Tips & Suggestions
Organise the build
Lay out the structural parts, motors, servos and fasteners before starting. Work through the assembly tutorial in sequence so you understand each joint before adding the next mechanism.
Map the electronics
Compare each connection with the circuit and wiring diagrams. Identify the three motor connections and separate wrist and gripper servo ports before applying power; disconnect power before changing wiring.
Begin with one movement
Start with a controlled single-joint or vertical movement using the documented setup. Keep the working area clear and observe the mechanism before combining commands into longer sequences.
Explore graphical commands
The illustrated Blockly interface includes arm angles, X/Y coordinates, Z movement, wrist rotation and gripper opening or closing. Use these controls to study how a command changes the arm's physical position.
Study the source code
Request the robotic arm and host computer source files. Compare a graphical movement sequence with its code representation and make small, documented changes rather than altering several settings at once.
Investigate the printed design
Use the STL files to examine the structural geometry and how the links fit together. Treat modifications as an engineering exercise: check clearances and motion before powering a changed assembly.
Build a supervised demonstration
For an educational session, separate assembly, wiring and programming into distinct stages. Have a knowledgeable adult supervise learners and keep hands away from moving joints and the gripper during operation.
Not Ideal For
Not ideal if you want a factory-assembled, immediately operational robot or a project that requires no mechanical assembly, wiring or software setup. Do not select it for a task that depends on a guaranteed lifting capacity, industrial duty cycle or certified positioning accuracy.
It is not an appropriate unsupervised play item for young children. Moving mechanisms and exposed electronics call for a controlled workspace and responsible supervision.
Frequently Asked Questions
Does the arm arrive assembled?
No. The full set is supplied as an unassembled DIY kit and requires self-assembly, wiring and software setup.
How is it programmed and controlled?
The controller supports Arduino programming and computer control through Wi-Fi or USB. A Blockly graphical interface is shown, including a Python tab. Follow the supplied technical documentation for setup.
Which technical files are available?
STL print files, robotic arm source code, a circuit diagram, an assembly tutorial and host computer source code are available on request.
What motors and power reference are shown?
The kit lists three 42-series stepper motors and two servos. The connection diagram shows a 12 V / 2 A power supply reference; check the assembly documentation before connecting power.
Important Notices & Disclaimers
This is a self-assembly electronics and robotics project. Read the technical documentation before assembly or operation. Verify wiring, supply requirements and software configuration before powering the controller.
Keep hands, hair, loose clothing and cables clear of moving joints and the claw. Disconnect power before adjustments or rewiring, and supervise learners during assembly and testing.
Assembled photographs illustrate the finished design; they do not mean the kit arrives assembled. Request the technical documents before beginning the project.
Shipping & Delivery
Package format
The full set is boxed as parts for DIY assembly. Plan for a build and setup process after delivery rather than expecting an assembled arm.
Delivery information
Review the delivery information and shipping terms provided during purchase. Keep your order confirmation for reference when contacting the store about a shipment.
Check parts on arrival
Compare the parts with the assembly documentation before starting. Retain packaging and contact the store with photographs and order details if anything arrives damaged or differs from your order.
Request project files
Request the technical documentation and source files so you can review the build sequence before assembling the delivered parts.
Illustrated dimensions are reference values. Assembly, configuration and responsible operation are required; follow the technical documentation and appropriate electrical safety practices.
