Space CoBot: a collaborative aerial robot for indoor microgravity environments
This paper presents a first contribution to the design of a small aerial robot for inhabited microgravity environments, such as orbiting space stations. In particular, we target a fleet of robots for collaborative tasks with humans, such as telepresence and cooperative mobile manipulation. We explore a propeller based propulsion system, arranged in such a way that the translational and the rota...
متن کاملMicrogravity pdf
Initial microgravity research centered around solving space flight problems created by the reduction in gravity’s effects experienced on orbit. How do you get the proper amount of fuel to a rocket engine in space or water to an astronaut on a spacewalk? The brief periods of microgravity available in drop towers at the Lewis Research Center and the Marshall Space Flight Center were sufficient to...
متن کاملGRADFLEX, Fluctuations in Microgravity
We present the results of experimental investigations of gradient driven fluctuations induced in a liquid mixture with a concentration gradient and in a single-component fluid with a temperature gradient. We also describe the experimental apparatus being developed to carry out similar measurement under microgravity conditions. The GRAdient Driven FLuctuation EXperiment (GRADFLEX) involves the i...
متن کاملCellular Effects of Microgravity
In the 1960's Soviet and U.S. investigators studied a variety of biological specimens on unmanned space vehicles. Most of these simple experiments reported normal growth and function, however, a few isolated results indicated increased growth in procaryotic cells (Taylor, 1974-review). Experiments with -E. coli K-12 (lambda) phage on over 20 Soviet flights, beginning with Vostok series, showed ...
متن کاملGranular convection in microgravity.
We investigate the role of gravity on convection in a dense granular shear flow. Using a microgravity-modified Taylor-Couette shear cell under the conditions of parabolic flight microgravity, we demonstrate experimentally that secondary, convective-like flows in a sheared granular material are close to zero in microgravity and enhanced under high-gravity conditions, though the primary flow fiel...
