The author argues the necessity of a knowledge-base-construction-support environment (KCSE) with which experts can arrange their knowledge on the conceptual level and review the whole system of extracted knowledge. The knowledge-information model in KCSE, which is based on coordinates operation rather than set algebra and the relational algebra, is presented.

The authors investigate the extraction of the transfer function of a monocular isoplanatic space-invariant optical imaging system in the cepstral domain for the purpose of estimating the range of an object, or isolated multiple objects, within the field of view, using only a single image frame. Range information is obtained by analyzing the optical blur characteristics, namely, the amount of object blurring measured in the frequency domain and the focal parameters of the lens system.

The author explores the feasibility of using Lisp to control a robot arm placed in a so-called block world to detect objects of different shapes and place them in desired locations or stack them in the order planned. Various artificial intelligence techniques are demonstrated, these including techniques in planning strategies, natural language understanding, and object recognition which are directly applicable to industrial applications.

The use of CAD systems for robot design requires the development of a perception function that can be used to simulate the optical sensors. Such a function is presented and used to simulate a camera and proximity sensors. The proximity sensors are small electrooptical devices consisting of a light source and a detector. The camera model takes into account the lens and the aperture characteristics. This perception function may be used for the offline programming of the robot, simulating any sensory feedback: the proximity sensors are used to control locally the trajectories of the robot, and the simulated camera is used to synthesize realistic images and to test vision algorithms.

The intrinsic complexity of patterns and the extent to which this notion is well defined are considered. An attempt is made to obtain the simplest possible description. Bit-map code and a Kolmogorov complexity program are used for image processing, saving computation time and hardware complexity. A circular-layer-code approach to feature extraction is used, and it is shown that low-level string-array coding can be used for pattern recognition. Other advantages of the approach are outlined.

Mobile robot control concepts using vision as a main sensor are considered. The control system has a global planner and a local planner. The former plans the global path as a sequence of vision subgoals. The local planner decides the path from one subgoal to the next while the robot is moving. For obstacle avoidance there are several problems in local path planning using vision only. To solve these problems, the authors propose local path planning by fusing information from vision and range sensors.

The authors present an overview of the research and development being carried as part of a major project on intelligent sensor-based robot systems. Results are reported on tactile sensing using a force-optical technique, the integration of such a sensor into a gripper finger, video-rate stereo vision processing, VLSI implementation of a novel vision architecture, inference imaging device using SHADOW technique, and highly adaptive self-tuned control. The system ultimately will incorporate twin-camera-head stereo vision, range finding, and intelligent tactile processing.

High-performance color sensing systems useful for color-code discrimination in flexible automation are considered. A color device is developed and is applied to three types of color-code-discrimination systems for use in flexible automation. The effectiveness of these discrimination systems is examined experimentally. Two of the systems are complete systems in which a symmetric-convex glass lens is mounted on the device to make the quantity of light uniform, and a photodiode is used to detect the quantity of light accurately. They can discriminate more than twelve chromatic colors that have different hue but the same lightness and saturation, and three achromatic colors. The third is a simplified system in which the output from a blue diode is neglected. This version can distinguish the same number of colors as the others under the same lighting conditions. The high performance attained experimentally suggests the possibility of using a color-code system instead of a monochromatic bar code system.
