Loss of Sensation, alternatively titled Robot of Jim Ripple (Russian: «Гибель сенсации» («Робот Джима Рипль»)) is a 1935 Soviet science fiction sound film directed by Alexandr Andriyevsky.

The film is based on the 1929 Ukrainian novel Iron Riot (also known as Robots are coming) by Volodimir Vladko.

The robots are not autonomous or intelligent, and controlled either by radio or by sound, for which purpose Ripple uses a saxophone.

A workers' delegation visits the factory to see that there are no strike breakers, and finds that actually it is the robots who works.

The robots are commanded by an officer sitting in a tank using a radio remote control device.
