As per the newspaper report, a person died after he went close to the robot arm of a machine. He went close to adjust a sheet that got dislodged when lifted by the robot arm.
It is normal practice to prohibit entry of personnel in robot working areas, as they do the work as per program.
It may not be practical to put proximity sensors on robot arms to stop robot movement as in that case their work output can be severely limited.
Instead, the entry to work area / reach of robots can be fenced and its entry door opening can be interlocked to stop operation.

Worker killed by robot...
As per a report, worker was killed during installation of a robot in a car manufacturing firm. Though the title leads to wrong conclusion, robots are lifeless and brainless and any action is due to wrong programming/setting by the concerned programmers/assemblers.
The robot must have been in commissioning stage or under trial runs. One has to do thorough event tree and fault tree analyses before putting the logic into field use.
Nobody should be allowed to be within the reach of the machine and suitable physical barriers and sensors/interlocks should be incorporated.
