Abstract : We report the design and development of the telescope control system (TCS) and observatory control software (OCS) for the robotic operation of the 50cm telescope. The primary tasks of the TCS is to facilitate very precise pointing and tracking of the main axes as well as handle peripheral sub systems such as secondary focus and the filter wheel. The TCS uses a computer and PSOC based controller. Many TCS related high level calculations such as topocentric and geocentric corrections and the pointing model etc. are carried out in a dedicated computer system, whereas low level control program runs in the PSOC. The OCS which is the top most layer in the control architecture, handles the filter wheel, the detector, the enclosure, the weather station as well as many safety mechanism. The OCS combined with the scheduler tool also facilitate un-maned robotic operation of the telescope. The entire software is based on client-server architecture and there are separate servers for the each sub-systems.
