Abstract
We present and discuss the role of robotic telescopes including GLORIA network in high--energy astrophysics, as well as related strategies. Numerous satellite projects focus on high energy astrophysics from X-rays to gamma-rays, however, a large fraction of objects of high-energy astrophysics emits also optical light, which is, in many cases, variable. The observation of these sources at optical wavelengths can provide valuable inputs for multispectral analysis of various categories of celestial high-energy (HE) sources. The magnitudes of numerous objects are bright and can be hence accessed by robotic ground-based observatories, hence these observations can contribute to investigations and analyses of HE sources. In addition to direct imaging, the Low dispersive spectroscopy (LDS) represent important optional strategy for RTs, taking into account the results from past extended LDS surveys with photographic telescopes/plates. .
