A navigation system for microswimmers

By applying an electric field, the movement of microswimmers can be manipulated. Scientists describe the underlying physical principles by comparing experiments and theoretical modeling predictions. They are able to tune the direction and mode of motion through a microchannel between oscillation, wall adherence and centerline orientation, enabling different interactions with the environment.

Simplified octopus-inspired swimming robot with soft asymmetric arms can replicate swimming patterns

Researchers at the National University of Singapore have developed a new robot inspired by one of the most intelligent aquatic animals on Earth: the octopus. This robot, presented in a paper published on the arXiv pre-print server, could be used both to complete real-world tasks underwater and to study the bio-mechanical underpinnings of octopus swimming.

Alternating between independent and cooperative behavior allows robots to find their way through crowds

Robots can navigate efficiently through crowds of people by cleverly alternating between independent and cooperative behavior, and in such a way that they disturb the people around them as little as possible. This is the result of a study by TU Professor Roderich Groß posted to the arXiv preprint server.

Can you feel sorry for a robot? Research indicates you can

A pitiful sound from tinny speakers, sad virtual eyes, trembling robot arms: It doesn't take much to feel sorry for a robot. This is the conclusion of a study by Marieke Wieringa, who will be defending her Ph.D. thesis at Radboud University on 5 November. But she warns that our human compassion could also be exploited; just wait until companies find a revenue model for emotional manipulation by robots.
