Material point method is an efficient and promising method for simulating complex stuff. Not used much in Astro, a lot in gaming, cartoons etc....
Worth having a look in comparison with SPH in simulation (for example those connected to the HERAS mission)
"Robohub is an online platform that brings together leading communicators in robotics research, start-ups, business, and education from around the world."
What is nice about robohub is that they generally give a look behind the scenes of interesting robotic studies.
This is currently a very trendy subject in navigation, indeed. In your case, how exactly do you resolve the ambiguity? why only one 2D marker? what would be the conclusion exactly?
A TED talk about Google X way of working and some closer look at the project loon (stratospheric balloon network for internet connection) by the 'moonshot captain' Astro Teller.
Today we released the Astro Drone app. People that have the Parrot AR drone can freely download the game. While they fly their drone in the real world, they are trying to dock to the ISS in the virtual world.
But the app is more than a game. Players can choose to participate in a scientific crowd sourcing experiment that aims to improve autonomous capabilities of space probes, such as landing, obstacle avoidance, and docking. If participating, the app extracts visually salient features from the images made by the drone's camera. The features are then combined with the estimates of the drone's state and uploaded. The data is then used in a research aiming to improve robot navigation.
Visit the main ESA website and you'll be greeted with a 6-minute Rosetta promo movie by a kickass Polish artist...
P.S. You can also find the video here.
P.P.S It seems I've just discovered a way to hijack old diigo entries ;-)
The Sun's gradual brightening will seriously compromise the Earth's biosphere within ~ 1E9 years. If Earth's orbit migrates outward, however, the biosphere could remain intact over the entire main-sequence lifetime of the Sun. In this paper, we explore the feasibility of engineering such a migration over a long time period.
