"Little Lost Robot" is a science fiction short story by American writer Isaac Asimov.

"Little Lost Robot" was adapted by Leo Lehman [de] for the 1962 ABC Weekend TV anthology television series Out of This World, which also marks the first appearance of Susan Calvin, played by Maxine Audley, in TV and movies.

It is then up to US Robots' Chief Robopsychologist Dr. Susan Calvin, and Mathematical Director Peter Bogert, to find it.

However, Dr. Calvin adds further urgency by postulating a situation whereby the altered law could allow the robot to harm or even kill a person.

The robot could drop a weight on a human below that it knew it could catch before it injured the potential victim.
