The cobot is not a class of robot. It is a claim about proximity and permission—enabled by passive mechanics, not active intelligence. Its invention solved one narrow problem: how to let humans move robots without triggering safety shutdowns. Its legacy is the shift from ‘safe-by-isolation’ to ‘safe-by-design-and-context’—a shift that puts the burden of verification on the user, not the manufacturer.
The cobot was invented in 1996 as a direct response to General Motors’ 1994 initiative to build robots safe enough to work beside people.

Mechanism: Human power, computer steering
The first cobots had no motors—they moved only when pushed by a human, while software redirected their payload along constrained paths.

Application: Where human dexterity meets machine consistency
Manufacturing and surgery were the two target domains from the outset—both require fine human control augmented by machine precision.

Name: A marketing term from a $5 contest
‘Cobot’ was coined in a naming contest—not by engineers, but by a postdoc—and won fifty dollars.

What it is and the problem it solves
A cobot is a robot built for direct physical interaction with humans in shared workspace. It solves the problem of integrating automation into tasks requiring real-time human judgment and dexterity—without cages.
How it works
The first cobots had no internal motive power. They relied entirely on human-provided motion. A computer guided redirection of payloads, but did not drive movement.
What works
Human-guided motion plus computer-guided redirection works for precision tasks where force amplification or path correction adds value—e.g., assembly guidance or surgical tool stabilisation.
What does not
It does not define a device category. ‘Cobot’ is a marketing term, not a standard. ISO/TS 15066:2016 sets requirements for collaborative operation, but the label itself carries no technical or regulatory weight.
What it changes
It changes how risk assessment is delegated—from engineering specification to application context. Safety becomes contingent on use case, not design alone.
Is it worth your time
Yes—if you work in manufacturing or surgery and need to assess how much safety assurance a ‘collaborative’ robot actually delivers. No—if you assume ‘cobot’ implies certified safety or standardised behaviour.
