Multi-objective optimization for socially aware robot navigation

Mobile robots are gradually making their way into a number of human-populated environments, including hospitals, malls and people’s homes. In order for these robots to interact with humans in their surroundings, they should respect a number of unspoken social norms that are associated with sharing a given environment with others. With this in mind, researchers at the University of Nevada, Reno have recently developed a non-linear, multi-objective optimization approach that could enable socially aware navigation...

Tomography and Instant Print of 3D Objects

Instead of making you wait hours or days, a new approach to 3D printing gives you the object almost at once. It seems like magic, but it’s all down to an adaptation of an already wildly successful algorithm. If you have ever watched a 3D printer slowly build up a 3D object one line at a time you will know that it quite quickly gets boring. The big problem with the standard machine is that...
