When you're outfitting an industrial robotics or cobot cell, the biggest fork in the road is whether you need a part that helps a robot feel or a robot that can move parts. The ATI Industrial Automation Mini45 and the Nachi MZ07 6-Axis Robot Arm sit on opposite sides of that decision. The Mini45 is a force/torque sensor that measures contact and load; the Nachi MZ07 is a full robot arm. These are very different investments in your automation project.
Quick Verdict
For precision sensing projects where you need to measure forces and torques along X, Y, and Z axes, the ATI Mini45 at $1,395 is the clear pick. For a ready-to-run robot arm, the Nachi MZ07 at $7,999.99 is the right path.

Where Each Product Wins
Where the ATI Mini45 Wins
The Mini45 is the lower-priced entry point into robotic sensing. It lets an existing arm or end effector detect contact, load, and tool interaction with precision. It's ideal for research and automation roles where you already have a robot and need to add a sense of touch.
Where the Nachi MZ07 Wins
The Nachi MZ07 is the complete motion package. It's built to move real parts in a full workcell and works as a complete unit, not just a component. If your project starts with an empty cell, this is the system that fills it.
Product Notes
ATI Industrial Automation Mini45
This is not a robot arm; it's the sensing brain that tells an arm what it's touching. The Mini45 measures force and torque simultaneously in X, Y, and Z axes, so you can detect contact, load, and tool interaction with exceptional accuracy. It was pulled from working automation and research equipment, and each unit comes complete with its integrated cable. The visible wear is minor and cosmetic, with no cracks, bends, or structural damage noted. For a used sensor, this is a straightforward way to add tactile feedback to an existing robot or end-effector setup. The trade-off is that it can't move anything on its own. You'll need a robot arm to attach it to; the sensor is the unit with its integrated cable. If you're building a force-sensing research rig, that's likely exactly what you want.
Nachi MZ07 6-Axis Robot Arm
If your project needs to reach, grip, and move parts, this is the full package. The Nachi MZ07 is a 6-axis industrial robot arm with a 723 mm reach, and it comes with the CFD controller and teach pendant needed to run it. That makes it a standalone automation unit rather than a component you have to buy separately. It's the higher-priced option in this comparison, but you're getting the complete motion system. The biggest limitation is payload: 7 kg means light-to-midrange work. Heavier parts will need a larger arm, and if you're only looking for sensing, a complete arm is more machine than you need. For test, measurement, and R&D environments that need a full motion platform, the MZ07 gives you the axes, reach, and control in one package.
Final Choice by Use Case
Choose the ATI Industrial Automation Mini45 if you already have a robot arm or end effector and need to add force/torque sensing. It's the lower-priced way to bring tactile intelligence to an existing cell.
Choose the Nachi MZ07 if you're starting with an empty workcell and need a complete robot arm. It also suits projects that need to move parts across a workcell. For most R&D and automation shops, the decision comes down to whether you need a robot to feel or a robot to move. The ATI Mini45 gives you the first; the Nachi MZ07 gives you the second.
