A used six-axis robot can cost a third of a new one, and still have fifteen years of life left. It can also arrive with a dead controller, no backup, a cracked wrist and a calibration history nobody can produce.
This guide is the buying process we would use in India: what to inspect, what paperwork to demand, how to test the arm before money moves, and the costs that appear after the crate is opened.
What used robots actually cost in India
| Class | Typical age | Indicative price | Main risk |
|---|---|---|---|
| 6-axis, 6–10 kg payload, major brand | 8–15 years | ₹6–15 lakh | Controller spares |
| 6-axis, 20–50 kg payload | 10–18 years | ₹8–20 lakh | Gearbox wear, shipping |
| SCARA, 3–6 kg | 6–12 years | ₹2.5–6 lakh | Limited application fit |
| Delta, high speed | 6–12 years | ₹3–8 lakh | Belt and bearing wear |
| Collaborative arm | 4–8 years | ₹8–18 lakh | Firmware and licence transfer |
These are asking prices for the arm and controller, before transport, duty, GST, integration, tooling and safety. A ₹9 lakh used arm routinely becomes a ₹18 lakh working cell. Import duty and GST depend on classification and current rules, so confirm with a customs broker rather than trusting a forum post.
The five questions that decide the deal
- Is the controller supported? A 2008 controller with no spare boards is a paperweight. Check part availability before the arm.
- Can the software licence be transferred? Some brands tie options to the controller serial and charge for reactivation.
- Is there a backup? Program archive, controller image and parameter file. No backup means you rebuild everything by hand.
- What was it doing? A robot that ran one pick-and-place cycle for a decade is usually healthier than one that ran a welding duty cycle.
- Who is selling it? A dealer with a test cell is easier to hold to a warranty than a broker who has never powered it up.
Inspection checklist before you pay
| Check | How | Reject if |
|---|---|---|
| Hours run | Controller service menu | No reading available at all |
| Backlash | Approach a point from two directions with a dial gauge | Over 0.1 mm at the flange on a small arm |
| Repeatability | 30 warm-up cycles, then 20 measured cycles | Spread far outside the datasheet value |
| Wrist and flange | Visual, then feel for play | Crash marks, cracks, seal damage |
| Brakes | Power off in a safe pose | Any axis drops |
| Cables and dress pack | Flex the harness through its range | Stiff spots, exposed conductors |
| Controller faults | Read the full fault log, not just the last one | Repeated overcurrent or encoder faults |
| Safety functions | Test E-stop path and safe-speed options | Bypassed or disabled functions |
Run the arm at production payload and production speed, not at 20% in a showroom. Warm it for at least 30 minutes first. Cold robots drift, and a seller who rushes this knows why.
Paperwork to demand
- Original purchase invoice or a documented chain of ownership.
- Controller backup and program archive on a USB drive you keep.
- Last calibration report, with date and method.
- Maintenance log: grease, belts, batteries, replaced parts.
- Fault history export from the controller.
- Software licence documents and any option keys.
- Declaration that the machine is not stolen or under finance.
- For imports: HS code, country of origin and customs documents.
Hidden costs after the crate arrives
| Cost | Typical range | Notes |
|---|---|---|
| Transport and rigging | ₹25,000–₹1.2 lakh | Depends on weight and access |
| Foundation and anchors | ₹15,000–₹1 lakh | Floor load and flatness |
| Safety guarding | ₹1–4 lakh | Driven by the risk assessment |
| End effector | ₹40,000–₹3 lakh | Gripper, vacuum, welding torch |
| Integration and programming | ₹75,000–₹4 lakh | Depends on cell complexity |
| Spares package | ₹50,000–₹2 lakh | Boards, brake, encoder, cables |
| Recalibration | ₹25,000–₹1 lakh | Often skipped, then regretted |
When a used robot is the wrong choice
- The application needs cleanroom, washdown or food-grade construction.
- You need a safety-rated collaborative arm with current certification.
- Cycle time is tight enough that a 15% slower arm breaks the business case.
- No spare parts exist in India and every repair becomes an import.
- You cannot get a backup or the software licence.
- The total installed cost lands within 20% of a new robot with warranty.
That last point matters more than people expect. Once integration, guarding and spares are added, the gap between used and new narrows. Buy used for the arm, but budget like you are buying a cell.
A sensible buying sequence
- Define the application, payload, reach and cycle time first.
- Shortlist two brands with local service and spare parts.
- Inspect in person, with a dial gauge and a warm-up run.
- Get the backup and fault log before paying anything.
- Pay in stages: token, inspection pass, delivery, acceptance.
- Budget the installation before signing, not after.
- Accept only after a measured repeatability test at production load.

How much does a used industrial robot cost in India?
Most used six-axis arms with a controller are quoted between roughly ₹6 lakh and ₹20 lakh depending on payload, age and brand. Installed cost is usually 50–100% higher once transport, guarding, tooling and integration are added.
Is buying a used industrial robot a good idea?
It can be, when the controller is still supported, spare parts exist locally, a backup and calibration report are available, and the installed cost stays well below a new robot with warranty.
What should I check before buying a used robot arm?
Backlash with a dial gauge, repeatability after a 30-minute warm-up, brake holding, wrist and flange damage, controller fault history, cable condition and safety functions. Then demand the backup, calibration report and maintenance log.
What paperwork should come with a used robot?
Original invoice or ownership chain, controller backup and program archive, calibration report, maintenance log, fault history, software licence documents and, for imports, customs paperwork.
How long does a used industrial robot last?
Major-brand arms routinely run 15–20 years in light duty. The controller, spare parts availability and gearbox wear usually decide retirement before the mechanical structure does.
Brand matters most for spares and support; see the industrial robot brand comparison.
