Industrial Robot Arms from $78.90: Yanmis, ZN, Stäubli RX130-B, or Nachi MZ07?

From a $78.90 six-servo teaching kit to a $7,999.99 Nachi MZ07 with teach pendant, these four robot arm listings serve very different jobs. Here's how to match price, condition, and capability to your intended use.

Last updated Aug 17, 2026

If you're shopping for an industrial robotics cobot or robot arm, the first thing you'll notice is how wide the price gap is. From a small teaching kit to a production arm with a teach pendant, these four robot arms serve completely different jobs. The price range alone tells you these are aimed at different buyers, so matching the machine to the task matters more than comparing specs side by side. The real decision isn't just "which one is best" but "which one is right for the work you actually need to do." Think of it as a choice between learning, visualization, and production.

Quick Take

These four entries are not interchangeable: one is a kit, one is a model, and two are used industrial arms. For a new, assembly-required teaching kit, the Yanmis 6DOF Mechanical Arm Claw Kit is the only new option in this group. For a small-scale visual reference, the ZN Six-axis Model gives you a model at a low price. If you need an industrial arm with a payload rating, the Nachi MZ07 comes with a controller and teach pendant. If you want a French-made arm, the Stäubli RX130-B is a used industrial arm.

Decision Matrix

Product	Best suited for	Keep in mind
Yanmis 6DOF Mechanical Arm Claw Kit	Classroom demos, teaching mechanical principles, or hobby assembly	Six servo motors and aluminum plate construction, but it's an educational kit rather than a production arm
ZN 1:10 Six-axis Model	Visualizing a six-axis robot layout at 1:10 scale	A 1:10 scale model, not a production arm
Stäubli RX130-B	Industrial automation setups that need a standard-construction arm with Stäubli controls	Standard construction type and Stäubli robotics controls
Nachi MZ07	Production or R&D work requiring a 7 kg payload	723mm arm reach and 7 kg payload

Product Notes

Yanmis 6DOF Mechanical Arm Claw Kit

This $78.90 kit is the only new option in the group, and it's built around six servo motors for front/back, up/down, and left/right gripping demonstrations. The brackets use 2mm aluminum plate, and the disc-shaped chassis helps the arm rotate smoothly. The kit's new condition and teaching focus make it a predictable first robot arm build. Choose it when you want to teach assembly and servo-driven motion rather than run a production cell. The tradeoff is that the kit is designed for learning, so it's not the arm you'd choose when you need a rated payload or reach for a production job.

ZN 1:10 Industrial Robot Manipulator Six-axis 3D Model

At $133.54, this ZN model is a 1:10 scale representation of a six-axis robot arm. It gives you a small physical reference for how a six-axis layout looks and moves, which can be useful for presentations or design visualization. This 1:10 scale model is a robotic arm assembly, and the scale is what separates it from the production arms. Choose it if your need is visualization at a low price. The limitation is that it's a model, not a working arm with a payload rating, so it can't take on real automation tasks.

Stäubli Industrial Robot Arm Automation Equipment RX130-B

The Stäubli RX130-B is a used industrial arm priced at $3,410.00. It comes from France, has a standard construction type, and uses Stäubli robotics controls. This is an industrial arm, unlike the teaching kit or the model. Its place in the lineup is clear: it occupies the middle ground between the small-scale options and the top-end Nachi. Choose it when you need a used arm with Stäubli controls and standard construction for an industrial setup. The limitation is that it's a used unit and a higher price than the two lower-priced entries, so it belongs in a plan for actual automation rather than a casual buy.

Nachi MZ07 6-Axis Industrial Robot Arm W/ CFD Controller & Teach Pendant 7kg

At $7,999.99, the Nachi MZ07 is the highest-priced arm and the one that lists both a 7 kg payload and a 723mm arm reach. It includes a controller and teach pendant, so it's the only package in this group with those items. For automation and R&D work, this is the arm that gives you the full control package. The unit is used, so the condition is part of the deal. Choose it when you need a six-axis arm with a real payload rating and pendant-based control. The limitation is the price and used condition, which put it at the top of the budget and require careful consideration of the exact unit.

Final Recommendation by Use Case

For teaching or hobby assembly, choose the Yanmis 6DOF Mechanical Arm Claw Kit.
For a scale model of a six-axis design, choose the ZN Industrial Robot Manipulator Six-axis 3D Model.
For an industrial setup, choose the Stäubli RX130-B.
For production or R&D work, choose the Nachi MZ07.

If the decision is about education and experimentation, the Yanmis kit leads the group. If the decision is about production payload, the Nachi MZ07 is the one with a concrete payload and reach. The ZN model and Stäubli arm fill the spaces between: one for visualization, the other for an industrial arm. Your goal should be the deciding factor: a hands-on learner needs a different machine than a production engineer. A kit won't move a payload, and a model won't run a line.
