Robot cops or Robocops may soon patrol the streets after police in the United States requested machines to execute dangerous criminals.

San Francisco police chiefs advocated utilising remote-controlled robots to apprehend offenders in exceptional instances.

The proposal brings us closer to the future cops immortalised in the 1987 science fiction blockbuster Robocop.

If the risk of loss of life is imminent, US cops seek to deploy lethal force by robots.Opponents have forewarned of a dismal future.

Attaching a laser-guided armed gadget that uses shotgun rounds to the robot is one method the robots might deliver terrible harm.

This can then be used to fire rounds at the subject.

Another approach would be to tie explosives to a robot and then use it to blow up a suspect, as was done in Dallas in 2016.

The primary distinction between a police robot and a service robot, for example, is the mission that they are trained to perform.
