The research could lead to robotic systems capable of changing their shapes, modalities and functions.

The resulting interactions produce movement toward the stopped smarticle, providing control that doesn't depend on computer algorithms. Credit: Rob Felt, Georgia Tech

Researchers have taken a new approach to developing robots—using smaller robots known as “smarticles” to unlock the principles of a potentially new locomotion technique.

They can be inserted in a pocket, attached to a sleeve or integrated into a wristband. Credit: Douglas Scott, Soldiers wearing TIDAM tokens could log in by getting near to a system, which would then prompt them to enter a PIN or a biometric as a second form of ID. They would be automatically logged out when they walk out of the system's range. Credit: Combat Camera, courtesy of CCDC C5ISR Center public affairs
