Human insights inspire solutions for household robots

ScienceDaily's AI News - Thu, 05/02/2015 - 14:12
People typically consider doing the laundry to be a boring chore. But laundry is far from boring for artificial intelligence researchers. To AI experts, programming a robot to do the laundry represents a challenging planning problem because current sensing and manipulation technology is not good enough to identify precisely the number of clothing pieces that are in a pile and the number that are picked up with each grasp. People can easily cope with this type of uncertainty and come up with a simple plan. But roboticists for decades have struggled to design an autonomous system able to do what we do so casually--clean our clothes.

Octopus robot makes waves with ultra-fast propulsion

ScienceDaily's AI News - Thu, 05/02/2015 - 08:30
Scientists have developed an octopus-like robot, which can zoom through water with ultra-fast propulsion and acceleration never before seen in human-made underwater vehicles. Most fast aquatic animals are sleek and slender to help them move easily through the water but cephalopods, such as the octopus, are capable of high-speed escapes by filling their bodies with water and then quickly expelling it to dart away. Inspired by this, scientists built a deformable octopus-like robot with a 3D printed skeleton with no moving parts and no energy storage device, other than a thin elastic outer hull.

Game theory explains social interactions of cancer cells

ScienceDaily's AI News - Wed, 28/01/2015 - 08:20
The interactions of cancer cells may be explained by using game theory. The Public Goods Game is part of game theory and is used in economics as a model to analyze the provision of common goods. There is an imbalance in the consumption of these goods between those that provide them and pay the production costs and those that do not pay but consume anyway -- a situation that is known in economics as the free rider problem. The researchers now applied this model to the cooperation between producing and non-producing members of a cancer cell population, in order to examine if the model is also applicable to biological processes, such as carcinogenesis.

People conform to the norm -- even if the norm is a computer

ScienceDaily's AI News - Wed, 14/01/2015 - 09:08
Often enough, it is human nature to conform. This tendency makes us follow the lead of computers, even if the machines give us the wrong advice. This is the finding of a study that investigates how people make judgment calls after playing role-playing video games. Real-life encounters and face-to-face contact with other people are on the decline in a world that is becoming increasingly computerized. Many routine tasks are delegated to virtual characters. People spend hours role-playing through virtual-reality video games by taking on the persona of a virtual character or avatar.
