Slime that can be controlled by a magnetic field can navigate tight spaces and grasp objects, making it ideal for possible uses inside the body
A robot made of magnetic slime with a custard-like consistency can navigate narrow passages, grasp objects and fix broken circuits. It could be deployed inside the body to perform tasks such as retrieving objects swallowed by accident.
Elastic robots capable of manipulating objects and fluid-based robots that can navigate tight spaces both already exist, but robots combining both properties are less common
