Component map
We help map J1-J6 joint classes, controller direction, power, cables, mounting assumptions, and end-effector path around the payload and reach target.
Arm builder kits
Build a robot arm sourcing package before buying disconnected parts.
If you are designing a prototype arm, send the target payload, reach, degrees of freedom, control preference, and cost target. We help map the joint sizes, controller path, cables, power, gripper options, and supplier questions before samples are ordered.
- Kit targets
- 3 / 5 / 10 kg concepts
- Scope
- joints + controls + tooling
- Best fit
- prototype and OEM teams
What you get
A practical sourcing answer, not a generic catalog link.
Build vs buy decision
The brief helps decide whether to build a custom arm, source a ready-made arm, reduce payload/reach, or start with a smaller sample package.
Sample plan and risks
Before buying samples, we flag common gaps: torque margin, thermal load, firmware, cables, brake needs, documentation, mechanical interface, and supplier continuity.
Buying checklist
Send these specs to get useful options.
Most bad robot quotes start with missing application details. These fields let us compare suppliers by fit, not only by price.
- Kit levels
- 3 kg, 5 kg, 10 kg concept packages
- Included sourcing
- Joints, controller, power, cables, gripper direction
- Buyer stage
- Prototype, feasibility, first sample, small batch
- What you receive
- Component map, supplier candidates, sample checklist
- Target payload, reach, DOF, speed, and accuracy expectation
- End-effector type and estimated tool weight
- Control preference: ROS, EtherCAT, CAN, vendor controller, or open question
- Prototype quantity, target unit cost, and delivery timeline
- Whether this is a lab prototype, OEM product, or private-label concept
Common buyer requests
When it makes sense to contact us.
A startup is deciding whether to build a 5 kg robot arm or buy an existing arm.
A research team needs J1-J6 joint classes for a prototype manipulator.
An equipment maker wants a private-label arm concept using China-sourced modules.
An OEM team needs a realistic sample plan before committing to custom tooling.
FAQ
Questions buyers usually ask before sending specs.
Is an arm builder kit a finished robot?
No. It is a sourcing and component package for teams that can design, assemble, program, and validate their own robot or work with a qualified engineering partner.
Why offer builder kits instead of only finished arms?
Builder kits serve a different buyer: robot builders and equipment makers that need component-level flexibility, lower prototype cost, or private-label development paths.
Can a kit become a production supply chain?
Yes, but only after sample testing, supplier validation, documentation review, and agreement on quality, warranty, and long-term availability.
Before you buy
We help check the sourcing risks before money is spent.
- End-effector weight and real payload margin
- Controller, protocol, and documentation quality
- Warranty, spare parts, MOQ, lead time, and payment terms
- Local integration, safety, installation, and support scope
