Robots integrated into groups of zebrafish and of one-day-old honey bees allow the two species to influence each other’s behavior.

Scientists engineered biomaterials similar to those chameleons use to change color and applied them to a robot.

A swarm of more than 1,000 small, puck-shaped robots can assemble into diverse patterns.

Animal robots have become a unique tool for studying the behavior of their flesh-and-blood counterparts.

University of Wisconsin researcher Barrett Klein’s robotic tungara frogs call to females.

Layer-by-layer manufacturing techniques could help re-make human body parts, or produce entirely new biocompatible machines.
