We will present aspects of the installation, commissioning, software development, and early operation of several new robotic telescopes: 1) the 1.2-m MONET/South telescope at Sutherland/ZA, the second Halfmann telescope for the MONET telescope network (the other telescope has been in operation at McDonald Observatory in Texas since early 2006); 2) a siderostat for a 0.5-m vacuum tower telescope for the new physics building of the Georg-August-Universität Göttingen; and 3) new developments for smaller (down to 0.5m) aperture telescopes. Special emphasis will be given to drive technology: using torque motors we adjust maximum slewing speeds of 10°/sec as standard. Although sufficient for most projects we are investigating even faster slewing speeds.

The on-orbit pointing performance of the Hubble Space Telescope is presented. Essentially all of the line of sight jitter is due to a rigid body motion of the main body of the satellite by reaction against its flexible solar arrays. Jitter caused by internal vibration is negligible. NGST, HST's possible successor, is a much larger observatory which will require a gain of an order of magnitude in pointing stability. It is shown how the use of a high orbit, changes in the telescope configuration, and the incorporation of active optics can bring about such an improvement.
This paper goes through an overview of Space Robotics is the development of machines for the space environment that perform Exploration, or to Assemble/Construct, Maintain, or Service other hardware in Space. Humans generally control space robots locally (e.g. Space Shuttle robotic arm) or from a great distance (e.g. Mars Exploration Rovers) Robot is a system with a mechanical body, using computer as its brain. Integrating the sensors and actuators built into the mechanical body, the motions are realised with the computer software to execute the desired task. Robots are more flexible in terms of ability to perform new tasks or to carry out complex sequence of motion than other categories of automated manufacturing equipment. Today there is lot of interest in this field and a separate branch of technology 'robotics' has emerged. It is concerned with all problems of robot design, development and applications. The technology to substitute or subsidise the manned activities in space is called space robotics. Various applications of space robots are the inspection of a defective satellite, its repair, or the construction of a space station and supply goods to this station and its retrieval etc. With the over lap of knowledge of kinematics, dynamics and control and progress in fundamental technologies it is about to become possible to design and develop the advanced robotics systems. And this will throw open the doors to explore and experience the universe and bring countless changes for the better in the ways we live.
Space robotics and manipulators — The past and the future
Control Engineering Practice, 1994
This paper presents the current state of the technology in space robotics. Some historical developments and the experience gained during those projects have been discussed. The challenge of space exploration and related danger requires even larger use of robotic devices. Many tasks and jobs are being automated. The exploration of the Moon and Mars requires autonomous, mobile robots to gather various information, measurements and data. The introduction of the Space Shuttle and related activities required an efficient robotic manipulator for in orbit operations. The Space Station Mir (in-orbit) and especially Space Station Freedom or Alpha (planned for the very near future) require advanced robots and manipulators. The Space Station Remote Manipulator System (SSRMS) and Special Purpose Dextrous Manipulator (SPDM) have been shown and briefly reviewed.Those and other robots for future missions are discussed in this paper.
Introduction to the Mechanics of Space Robots
Springer eBooks, 2012
This text started as a collection of notes of the lectures on Space Robotics given by the author to the students of the International Master on Space Exploration and Development Systems (SEEDS). The aim of the course was the study of the automatic machines aimed to operate both autonomously and as a support to astronauts in space exploration and exploitation missions, with particular attention to the devices designed for planetary environment, including small planets, comets and asteroids. This material was then completed and made more systematic so that it can hopefully be useful not only to the students of that course but also to those who have an interest in the wide and much interdisciplinary field of space robotics, and in particular in its mechanical aspects. The focus is drawn mainly on the mechanics of space robots: the author is well aware that, even in this specific field, it is far from being complete and that robots, like all mechatronic systems, are so integrated that no single aspect can be dealt separately. Many important aspects are either dealt with only marginally or altogether left out. The very important topics of the control and the behavior of robots, for instance, are only marginally touched, even if their influence on the mechanical aspect to which this book is dedicated is not at all marginal. The structure of the book is so organized: A Note on the Illustrations I have made every effort to seek permission from the original copyright holders of the figures, and I apologize if there are cases where I have not been able to achieve my objective. This applies in particular to figures taken from the web, like Figs. 4

Space Robotics: Past, Present, & Future
2022
Robotics and space technology are the most happening and tech-driven sectors in today's scenario. The early 21 st-century pop culture witnessed the rise of robotics and its application in space like R2D2 (Star Wars, 1977), Wall-E (2008), Terminator (2003), etc. Robots like Legacy robots, Atlas, are some of the well-known robots that are used in fields involving challenging environments and tasks. Space robots have developed significantly in the past few decades and produced robots like robotic arms and astronaut assistants.
Bringing Old Telescopes to a New Robotic Life
Revista Mexicana de Astronomía y Astrofísica Serie de Conferencias, 2019
We present the development from its origin to the implementation of new hardware and software for telescope control. This system has been designed to be adaptable to old decommissioned telescopes. We will show how we applied a low-cost system to refurbish three telescopes belonging to the Pontificia Universidad Cat´olica de Chile to allow their remote and automatic use with a web-based interface.

In this first of three short papers, I introduce some of the basic concepts of space engineering with an emphasis on some specific challenging areas of research that are peculiar to the application of robotics to space development and exploration. The style of these short papers is pedagogical and this paper stresses the unique constraints that space application imposes. This first paper is thus a general introduction to the nature of spacecraft engineering and its application to robotic spacecraft. I consider the constraints and metrics used by spacecraft engineers in the design of spacecraft and how these constraints impose challenges to the roboticist. The following two papers consider specific robotics issues in more detail.
