Run the Provenance Test
The used market is real and the savings can be substantial. It runs on two channels: specialist refurbishers and dealers such as RobotWorx in the US and Eurobots in Europe, who recondition and warranty used arms, and untested equipment sold as-is through general auctions and liquidations. What you receive alongside the hardware varies enormously between the two.
The Bot Scout provenance test asks five questions before price: what application did this robot run and for how many hours, does the controller software have a transferable licence, is the controller generation still supported by the builder, are spare parts still manufactured, and does documentation and backed-up program memory come with it.
An arm is mechanically durable and a controller is not. Obsolete controller generations, expired software licences, and lost program backups are the failures that turn a bargain into scrap, and none of them are visible in a photograph.
| Check | Good outcome | Warning sign | Consequence if ignored |
|---|---|---|---|
| Application history | Documented hours and duty cycle | Unknown prior use | Wear you cannot assess |
| Controller support | Generation still supported | End-of-life controller | No parts, no software updates |
| Software licences | Transferable in writing | Licence tied to prior owner | Cannot legally run the software |
| Spare parts | Still manufactured | Parts only from breakers | Downtime measured in weeks |
| Documentation and backups | Supplied with the robot | None available | Reprogramming from scratch |
| Safety assessment | New application assessed | Assumed to carry over | Non-compliant installation |
When Used Makes Sense
Used equipment fits a stable, well-understood task where your team already has robotics capability, spares are available, and the cell design is not software-dependent. That combination is common in established manufacturing and rare in a first project.
A first automation project is the worst case for used equipment, because the buyer cannot yet distinguish a good arm from an expensive problem. If it is your first cell, the integrator relationship matters more than the saving — see the industrial robots for sale guide.
Software-dependent fleet systems are the riskiest used purchase of all, since licences and fleet software may not transfer with the hardware, as noted in the warehouse robots for sale guide.
- Require documented application history and running hours.
- Confirm the controller generation is still supported.
- Get software licence transferability in writing.
- Check spare-part availability before agreeing a price.
- Budget a new safety assessment for the new application.
Safety Does Not Transfer
A safety assessment covers an application, not a machine. Installing a used robot in a new cell requires a new assessment regardless of how it was certified at its previous site — ISO 10218-1:2025 sets the robot safety requirements.
OSHA notes that many robot incidents occur during programming, setup, adjustment, testing, and maintenance, which is exactly the phase a used installation spends most time in.
Budget refurbishment honestly: cables, seals, batteries, belts, and grease all age. A robot that has sat unpowered for a long period may also have lost its program memory, which is a cost rather than an inconvenience.
Bottom Line
A used industrial robot is sound when history, controller support, licences, and parts are documented. Budget a new safety assessment and refurbishment, and avoid used equipment for a first project.
Confirm controller support and licence transferability in writing before agreeing any used-robot price.
FAQs
Are used industrial robots worth buying?
They can be, for a stable well-understood task where your team has robotics capability, spares are available, and the controller generation is still supported by the builder.
What is the biggest risk with a used robot?
The controller rather than the arm. Obsolete controller generations, non-transferable software licences, and missing program backups are what turn a bargain into scrap.
Does a used robot's safety certification transfer?
No. Safety is assessed per application, so installing a used robot in a new cell requires a new assessment regardless of its previous certification.
Should a first automation project use second-hand equipment?
Usually not. A first-time buyer cannot easily distinguish a sound arm from an expensive problem, and the integrator relationship matters more than the saving.
