Massive Spectroscopy in Dense Environment - from emerging technologies to new science

In this presentation, we will present new revolutionary developments in terms of miniaturisation of robotic fiber positioning system (now reaching 6.2mm of pitch) conducted at EPFL. Although this technology development was initiated primarily by cosmology science case, porting these developments on the VLT will open new opportunities in particular regarding massive spectroscopy in dense environment (galaxy clusters, star clusters, complex nebulae, spectroscopic transients ...).
