4-Axis Delta Parallel Robot — 3 kg Payload, Ø600 × 120 mm Envelope, ±0.02 mm Repeatability, 400 W Servo + Harmonic Drive
A delta parallel robot (also called a spider or parallel-kinematic robot) drives a single light end plate from three base-mounted arms through carbon-fibre rods. Because nearly all the moving mass stays at the base, a delta accelerates far harder than a serial arm of the same payload, which is why it is the standard choice for high-rate pick-and-place over conveyors. This unit carries 3 kg over a Ø600 × 120 mm envelope at ±0.02 mm repeatability, with a 4th rotary axis on the end plate.A delta (parallel) robot is the arrangement you see over packaging lines: three arms driving one light end plate through carbon-fibre rods, so almost all the moving mass stays at the base. That is what lets a delta pick and place several times per second where a serial arm of the same payload would still be accelerating. This is the harmonic-drive servo build: three 400 W AC servos through 1:50 harmonic reducers, 3 kg payload over a Ø600 × 120 mm envelope, and ±0.02 mm repeatability. The frame is CNC-machined metal throughout with carbon-fibre linkage rods and zero-backlash joints. A fourth rotary axis at the end plate is fitted, so parts can be oriented as well as moved. It arrives as a working set — arm, control card with the drives built in, and power supply. Programming is done from a PC application with drag-to-teach, an on-screen simulation of the motion before you run it, and conditional and loop statements for real sequences rather than fixed point-to-point playback. Shipping is from our Singapore warehouse. Crated weight is about 10 kg, so the rate is calculated at checkout: USD 219.99 by SingPost Speedpost Priority, USD 399.99 by DHL Express Worldwide for 3–5 business days, or USD 15 within Singapore.What can you use it for? High-rate pick-and-place from a moving conveyor into trays, cartons or thermoformed packs Food, bakery and confectionery primary packing where cycle rate matters more than reach Electronics and small-part sorting, kitting and tray loading Pharmaceutical and cosmetic secondary packaging — blister, vial and sachet handling Laboratory automation, sample sorting and repetitive test-piece transfer Robotics research and teaching on real parallel kinematics rather than a desktop model Who is it for?Machine builders, packaging-line integrators, contract manufacturers and automation labs that need delta-class cycle rates without paying tier-one industrial robot prices.Compatibility Supplied complete: robot body, control card with drives built in, and power supply — no separate cabinet to specify Programming from a Windows PC application: drag-to-teach, on-screen motion simulation before running, conditional and loop statements, live position and status feedback End effectors: the end plate takes vacuum cups, magnetic or pneumatic grippers; a vacuum switch such as the DPSN1 gives the controller a part-present signal Mounting: inverted above the work area on a frame or gantry of your own; the working envelope is Ø600 mm × 120 mm below the base plate Sibling build: a planetary-gearbox closed-loop stepper version (1.5 kg, 1:10, ±0.1 mm) and custom envelope sizes are available on request Specifications Kinematics 3-axis delta parallel linkage + 4th rotary (wrist) axis Payload 3 kg Work envelope Ø600 mm × 120 mm high Repeatability ±0.02 mm Motors 3 × 400 W AC servo Joint reduction Harmonic drive, 1:50 Structure CNC-machined all-metal frame, carbon-fibre linkage rods, zero-backlash joints Supplied with Robot body × 1, control card with integrated drives × 1, power supply × 1 Programming PC host software — graphical drag-to-teach, simulation view, conditional and loop flow control, real-time position and status feedback Homing Safe auto-homing; retracts automatically if a limit is pressed or overtravelled Also available Planetary-gearbox closed-loop stepper version (1.5 kg payload, 1:10 reduction, ±0.1 mm) and custom envelope sizes — contact us Shipping Ex Singapore warehouse; crated approx. 10 kg; SingPost Priority or DHL Express, rate shown at checkout Certification Supplied as a machine sub-assembly. No CE machinery certification is included — the integrator is responsible for guarding, risk assessment and conformity in the destination market What's in the box Harmonic + 400 W servo, 3 kg payload, with 4th rotary axis: 1 × delta robot body with 4th rotary axis, 1 × control card with integrated servo drives, 1 × power supplyShipping and returnsShips from our warehouse in Singapore with tracking. Parts and accessories are charged by parcel weight, the same rates everywhere: $11.99 up to 250 g, $19.99 to 500 g, $34.99 to 1 kg and $59.99 to 2 kg. Orders over $100 that stay under 500 g ship free. Standard tracked runs 5–18 business days; DHL Express (3–5 business days) is offered at checkout if you need it sooner. Within Singapore: $6, or free over $110. Assembled robot-arm kits over 2 kg are built and calibrated to order in Singapore (dispatch in 7–10 business days) and ship worldwide at carrier cost: SingPost Speedpost Priority from $124.99 (10–14 business days) or DHL Express from $229.99 (3–5 business days), shown at checkout. 7-day returns; defective items are replaced or refunded with shipping covered. Import duties, where charged by your country, are paid by the recipient.One parcel, one shipping charge: small parts travel together, so the postage on a single 70 g servo is the same as on six of them. A 500 g parcel holds roughly six servos plus horns and cables — which is also about where an order passes $100 and ships free. If you are buying one small item, it is usually worth checking what else you will need for the same build.Frequently asked questionsWhy choose a delta robot over a 6-axis arm?Speed. A delta keeps the motors at the base and moves only carbon-fibre rods and a light end plate, so it accelerates much harder than a serial arm of equal payload. The trade-off is a flat, limited work envelope and no ability to reach around obstacles — which is exactly the right trade for picking off a conveyor.What is the difference between the servo and the stepper version?This servo build uses three 400 W AC servos through 1:50 harmonic drives: 3 kg payload and ±0.02 mm repeatability. The stepper build uses 57-frame closed-loop steppers through 1:10 planetary gearboxes: 1.5 kg payload and ±0.1 mm. Both share the same Ø600 × 120 mm envelope.Do I need to write code to program it?No. The supplied PC software teaches positions by dragging the arm on screen and supports conditional and loop statements for real sequences. Remote setup support is included.What does the fourth axis do?It rotates the part at the end plate, so you can correct orientation while placing — aligning a label, seating a part in a nest, or squaring a pouch — rather than only moving in X, Y and Z.Is it CE marked?No. It ships as a machine sub-assembly without CE machinery certification. Whoever puts it into service is responsible for guarding, risk assessment and conformity in the destination market. Please factor that into your project before ordering.How does it ship and what does freight cost?It ships from our Singapore warehouse, crated at about 10 kg. The rate is calculated at checkout and is not included in the machine price: USD 219.99 by SingPost Speedpost Priority, USD 399.99 by DHL Express Worldwide for 3–5 business days, or USD 15 within Singapore.What end effector should I use?The end plate is drilled to take your own tooling. Vacuum cups suit flat or filmed products; add a vacuum switch so the controller knows a part is actually held before the arm moves.
