TL;DR: This report describes ongoing research on a working system which drives a vehicle through cluttered environments under computer control, guided by images perceived through an onboard television camera.
Abstract: This report describes ongoing research on a working system which drives a vehicle through cluttered environments under computer control, guided by images perceived through an onboard television camera. The emphasis is on reliable and fast low level visual techniques which determine the existence and location of objects in the world, but do not identify them

TL;DR: This paper focuses primarily on the implementation of the functional elements and the real world problems encountered by the manipulator system, as opposed to the specific algorithms and equations, since it feels that these two factors are under emphasized in the literature.
Abstract: This paper describes the development of a practical manipulator system The manipulator requirements dictated by space exploration, the functional elements which meet those requirements, and the problems encountered in implementing those requirements are discussed The paper focuses primarily on the implementation of the functional elements and the real world problems encountered by the manipulator system, as opposed to the specific algorithms and equations, since we feel that these two factors are under emphasized in the literature Specific topics discussed include user interfaces, trajectory planning, safety and obstacle avoidance, and link motion control Implementation emphasis has been placed on flexibility, minimizing complexity, and increasing reliability

TL;DR: In this paper, the effect of display type on the measures and criteria which were apparently optimized by the subjects was determined, based on a series of simulator experiments involving ship transit and obstacle avoidance.
Abstract: : In existing man-machine systems the human operator is typically presented a predesigned display and he must adapt his control techniques in an attempt to optimize overall system performance. Ultimate performance achieved may not rise to the designer's expectation or to the operator's capability because the design process does not account for the operator's adaptability. In this research program, ship control performance of the Officer of the Deck (OOD) was observed and analyzed in a series of simulator experiments involving ship transit and obstacle avoidance. Three types of displays were included in the analysis. OOD control rules, and measures and criteria which describe the control technique used as well as the criteria employed in controlling the ship were derived from the individual performance data. The effect of display type on the measures and criteria which were apparently optimized by the subjects was determined. (Author)
