Cobot or Industrial Robot?

Compare speed and payload against the task

Start with the job, not the category. NIST's 2021 report on integrating collaborative robots into workcells at small and medium-sized manufacturers notes that cobots are generally smaller and typically carry lighter payloads than traditional robots, and it advises users to consider that cobots are slower and generally less accurate than regular robots. If your station needs heavy parts, long reach or a short cycle time, a conventional arm behind guarding may be the only option that meets takt. If the parts are light and the cycle is relaxed, the cobot's gentler motion costs you little. Time the cycle you need with real parts and fixtures before choosing.

Count the cost of guarding and floor space

Guarding changes both the bill and the layout. The NIST report observes that the initial cost of integration and disruption to production can be minimised if no safety cell is required, and notes that a safety cell is typical when a traditional robot is used instead of a cobot. ISO 10218-2:2025, which sets requirements for integrating industrial robot applications and robot cells, applies to the whole application either way, so that saving disappears if the assessment of your tool or workpiece calls for scanners or fences. Sketch the cell both ways, with the floor area each version takes and how material reaches it, because space on a crowded shop floor has a real cost.

Budget integration for either type

A cobot's arm price can mislead you about the project total. NIST reports that integrators advise small and mid-sized manufacturers to budget around three times the price of the cobot system for integration, while some Manufacturing Extension Partnership experts have seen as little as half to one times the cobot cost for development, fixturing, end effectors and deployment. Conventional cells carry their own integration bill, with guarding and safety controls on top. In October 2026, listed prices for the arms on this site's cobot page ran from about $25,000 for the AUBO i5 and Techman TM5-700 to about $80,000 for the KUKA LBR iiwa 14 R820, so compare complete cell quotes rather than arms.

Plan for the people who will reteach it

The deciding factor is often who will change the programme when the product changes. NIST's report offers three ways to pick a first workcell: from past experience, through a quadrant of complexity against impact, or by weighting key elements, and the workforce is among the factors it weighs. If your line runs many variants in small batches and your own technicians will reteach the robot, a cobot with simple programming tools may suit you. If one product runs for months and an integrator will maintain the code, a conventional arm's speed is usually worth its extra complexity. Assess the training each option needs before you order.

Common questions

Do cobots need a systems integrator?

Not always. Some smaller manufacturers set up simple cobot cells with their own engineers, but someone competent must still carry out the risk assessment, validate the safety settings and document the cell. You can buy that help for a first project and build in-house skills for the next.

Which is cheaper to run, a cobot or an industrial robot?

It depends on utilisation. A fast industrial arm spreads its cost over more parts per shift, while a cobot can work out cheaper where output is modest and staff reteach it often. Compare the cost per good part over the equipment's life for both options.
