Lightweight space robots could be used for many of these tasks, provided they would be dexterous enough and more flexible in their perception of the working environment than the present ones. The employment of vision enables a robot to grasp, and manipulate inspected objects autonomously. The paper describes the interaction between robot, camera and a multisensory gripper for performance of local repair tasks, e.g. opening the jammed solar panel of a satellite, by 3D active inspection. Central points of interest have been the composition of information acquired from image sequences as well as the object localization in the robot work space and the supervision of grasping procedures. Besides a description of the system structure and the underlying ideas, experiences and results from terrestrial lab experiments are presented in order to discuss the limits and possibilities of the use of vision for space robotic tasks.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

One of these is perspective foreshortening, an effect that occurs when a surface is viewed at a sharp angle. Because each stereo camera has a slightly different view, the image of the surface is more compressed and occupies a smaller area in one view. These effects cause problems because most stereo methods compare similarly sized regions (using the same-sized windows in both images), tacitly assuming that objects occupy the same extents in both images. Clearly this condition is violated by perspective foreshortening. We show how to overcome this problem using a local spatial frequency representation. A simple geometric analysis leads to an elegant solution in the frequency domain which, when applied to a Gabor filter-based stereo system, increases the system's maximum matchable surface angle from 30 degrees to over 75 degrees.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

The control objective is to adaptively compensate for the unknown nonlinearity of robot manipulators which is represented as a fuzzy rule-base consisting of a collection of if-then rules. The algorithm embedded in the proposed architecture can automatically update fuzzy rules and, consequently it is guaranteed to be globally stable and to drive the tracking errors to a neighborhood of zero. Focusing on realization, hardware limitations such as traditional long computation time and excessive memory-space usage are also relaxed by incorporating heuristic concepts, which reveals the flexible feature of this architecture. The present work is applied to the control of a five degree-of-freedom (DOF) articulated robot manipulator. Experiment results show that the proposed control architecture features fast convergence.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

This method utilizes the displacement and force information obtained by \"active search motion\" of a robot. A new neural network configuration for this detection is proposed. It consists of two multilayer networks (primary and secondary network). The primary network learns the movable space (constraint) obtained by the search motion. By the generated link weights which reflect the movable space, the secondary network determines the type and the orientation of the constraint.

A cooperative control algorithm considering the flexibility of macro/micro manipulators is proposed. After the differential equation of the error vector system is derived, a method of designing feedback gain matrices is shown for linearizing the system. To verify the efficiency of the algorithm, experiments are done on carrying an object by two industrial robots.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

However current feature based localisation techniques can become unstable if the robot drives in such a way that its sensors cannot recognise these features. A novel dynamic path planning approach is presented that supports the data acquisition for the localisation process as well as the extraction of new feature while exploring an a priori unknown indoor environment. Real experiments on the authors' mobile robot Roamer have shown that the overall localisation stability and the feature extraction process were improved significantly while exploring an unknown environment.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

The individual robots in the array can be implemented in a variety of technologies with different sizes. Programmability is the common necessary characteristic for an IMS; the array, with groups of contiguous robots acting in unison, can be programmed to various configurations to have the effect of imparting force fields on objects being carried on its surface. The appropriate choice of force fields is shown to cause parts placed on the array to be moved in manners that are useful. These include such functions as translation, rotation, orientation alignment, spatial filtering and the feeding of parts. The use of the IMS is described for primitive assembly operations. Limitations of the approach, extensions and possibilities for future work, particularly in microelectromechanical system (MEMS) implementations, are discussed in detail in the paper. The practicability and the programming of such an IMS-based active assembly bench was explored in a simulated environment.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.
