Why in news
Researchers at Princeton Engineering developed a magnetically controlled robot that maintains stable shapes without motors by applying mathematical principles derived from ketchup bottle caps.
Background
The study, published on June 15, 2026, by Glaucio Paulino's team, identified 'pseudocreases' as a factor in shell stability. This allows for the creation of robots that can transition between multiple stable configurations using magnetic fields rather than internal motors.
Facts for Prelims
- S&TPseudocreases: Structural features in curved shells that allow for multiple stable configurations.
