Robots in Easy-to-Manage Swarm Share Data for Optimal Planning

Gliding fingers across the tablet shift the position of red beams of light that appear on the floor. An algorithm causes the robots to seek out the light and attempt to evenly cover the lit areas. (Photo credit: Georgia Tech.)

A new system designed at Georgia Institute of Technology can control a swarm of robots, simply by using one finger to shift a beam of light. Each robot is also flexible enough to develop its own plan, based on input received from others in the swarm. …

Understanding and Improving Scene Recognition

The first layers (1 and 2) of a neural network trained to classify scenes seem to be tuned to geometric patterns of increasing complexity, but the higher layers (3 and 4) appear to be picking out particular classes of objects. Photo courtesy of the researchers.

Scene recognition and object recognition systems could work in tandem, according to a paper presented last weekend at the International Conference on Learning Representations. In fact, the researchers believe that one might reinforce the other. The findings come after researchers created the most successful scene classification …

Coming Soon: Superintelligence

In Daniel Wilson’s book, Robopocalypse, Archos is the supremely intelligent sentient being unwittingly unleashed upon the world. He is self-aware, self- improving and bent on his own self-preservation and destroying humankind.

Programming underwater robots can be a tedious task. Engineers have to break down missions into small, simple tasks, and then write scripts for each low-level command. Now a new approach, developed by researchers at MIT, will enable the robots to figure out more on their own. …

A Soft Material that Moves When Exposed to Light Could be Ideal for Robotics

When exposed to non-uniform light, the SP-BZ gel moves. This diagram shows how the material moves over time when only the ends are exposed to light. (Photo Credit: University of Pittsburgh)

Researchers at the University of Pittsburgh’s Swanson School of Engineering have designed a synthetic polymer gel that can generate enough chemical energy to shape-shift and propel itself forward. The researchers modeled their research after the single-celled organism euglena mutabilis, which processes energy to expand and contract …

Strain Sensor Could Help Robots Read Facial Expressions

A new facial expression sensor reported in the journal ACS Nano could help robots decipher our feelings. Developed by researchers in Korea, the stretchable, transparent sensor is worn on a person’s face, near the side of the lip. The sensor, which can detect small strains on …

European researchers have demonstrated a prototype robotic system that can move a car from a parked position. The system, called the Autonomous Vehicle Emergency Recovery Tool (AVERT), is designed to remove vehicles that are blocking entry or positioned suspiciously close to vulnerable positions such as tunnels, …

Cobalt isotopes that have been sitting in British storage ponds since the 1950s are finally being recovered, using miniature submarines. The project involves moving hundreds of the cartridges retrieved from Sellafield Ltd’s Pile Fuel Storage Pond and First Generation Magnox Storage Ponds. “A few years ago …
