Pushy robots learn the fundamentals of object manipulation

Researchers have compiled a dataset that captures the detailed behavior of a robotic system physically pushing hundreds of different objects. Using the dataset — the largest and most diverse of its kind — researchers can train robots to ‘learn’ pushing dynamics that are fundamental to many complex object-manipulation tasks, including reorienting and inspecting objects, and uncluttering scenes.

Model system for distribution of more accurate time signals

Physicists have demonstrated the first next-generation ‘time scale’ — a system that incorporates data from multiple atomic clocks to produce a single highly accurate timekeeping signal for distribution. The new time scale outperforms the best existing hubs for disseminating official time worldwide and offers the possibility of providing more accurate time to millions of customers such as financial markets and computer and phone networks.

Clingfish biology inspires better suction cup

A team of engineers and marine biologists built a better suction cup inspired by the mechanism that allows the clingfish to adhere to both smooth and rough surfaces. Researchers reverse engineered the clingfish’s suction disk and developed devices that cling well to wet and dry objects both in an out of water. The devices can hold up to hundreds of times their own weight.
