PLATO control and robotics

چکیده
PLATO, the ‘PLATeau Observatory’, is a robotic Antarctic observatory developed by UNSW for deployment to Dome A, the highest point on the Antarctic plateau. PLATO is designed to run autonomously for up to a year, providing power, communications and thermal management for a suite of scientific and site-testing instruments. To achieve this degree of autonomy, multiple-redundant Linux-based ‘supervisor’ computers, each with their own watchdog-timer and Iridium satellite-modem, communicate with each other and with the outside world. The active supervisor computer monitors and controls the PLATO power distribution, thermal and engine management subsystems via a CAN (Control Area Network) bus. High-bandwidth communication between the instruments and the supervisor computers is via a 100 Mbps Local Area Network. Data is stored in cold-verified flash memory. The PLATO computers monitor up to 140 analog channels and distribute electrical power and heating to 96 current-monitored channels via an intelligent loadshedding algorithm.

The PLATO Dome A site-testing observatory: power generation and control systems.
The atmospheric conditions above Dome A, a currently unmanned location at the highest point on the Antarctic plateau, are uniquely suited to astronomy. For certain types of astronomy Dome A is likely to be the best location on the planet, and this has motivated the development of the Plateau Observatory (PLATO). PLATO was deployed to Dome A in early 2008. It houses a suite of purpose-built site...
متن کاملDual Space Control of a Deployable Cable Driven Robot: Wave Based Approach
Known for their lower costs and numerous applications, cable robots are an attractive research field in robotic community. However, considering the fact that they require an accurate installation procedure and calibration routine, they have not yet found their true place in real-world applications. This paper aims to propose a new controller strategy that requires no meticulous calibration and ...
متن کاملHappiness in Plato’s Theory of Philosopher- King
Plato in Theory of Philosopher-King believes that all of the members of ideal city-state, whether ruler or citizens, will attain happiness if the philosopher is the ruler. But there are paradoxes in the theory and the bases of the happiness are unstable too. In other words, Plato in his theory presents hierarchical dualities (Intelligible/Visible world, Episteme/ Doxa,True/ Untrue Or Shadow, …)...
