A comparison of the two technologies by payload, speed, batch size and safety criteria.
Cobot or traditional industrial robot? This is the dilemma that businesses new to automation face most often. They are not competitors; they are tools that serve different needs.
Strengths of the cobot
- No safety cage required: Force and speed limiting is assessed under ISO/TS 15066; in most applications an area scanner is enough.
- Quick installation: Programmed in hours by hand teaching and commissioned in 4-8 weeks.
- Flexibility: Moved between stations on a mobile cart and suited to frequently changing jobs.
- Low investment: A typical cobot station ranges from 1.2 to 2.4 million TRY.
Strengths of the traditional robot
- Speed and payload: Hundreds of cycles a minute, payloads up to 800 kg
- Repeatability: Accuracy of ±0.02 mm
- Serial production: Lowers unit cost on high-volume lines with fixed parts
- Harsh environment: Versions resistant to weld spatter, paint and high temperatures
Decision table
| Criterion | Cobot | Traditional robot |
|---|---|---|
| Payload | 3 – 30 kg | 3 – 800 kg |
| Speed | Medium | High |
| Batch size | Small – medium | Medium – serial |
| Installation time | 4 – 8 weeks | 12 – 36 weeks |
| Safety | Fence-free possible | Fence / light curtain |
A real decision example
A plastics manufacturer compared a column robot and a cobot for palletizing. A speed of 6-8 cartons per minute was enough on its line and it needed to move between three lines; the cobot station at 1.6 million TRY paid back in 11 months. In the same process, a dairy plant needing 14 cartons per minute chose the column robot.
Programming and operating differences
Cobots can be programmed by a field engineer through hand teaching and graphical interfaces, whereas traditional robots require a robot language or offline programming. On the other hand, the simulation and offline programming tools of traditional robots save time on complex trajectories and multi-robot cells. For maintenance, both technologies need annual oil and cable checks; cable life is generally longer in cobots thanks to their lower motion loads.
Hybrid solutions
Many plants use both technologies: the main line runs with robots, while frequently changing finishing and inspection stations run with cobots. Building a common safety and data infrastructure in your contract makes future expansion easier.
