A Simplified Teaching Method of a Playback-Type Industrial Robot

The present study is devoted to the development of a simplified teaching method whereby the control data of the 3-dimensional operations of a playback-type industrial robot can be stored in a personal computer. The control data of the 3-dimensional operations are given using an instruction wand handled by an operator. The operator\u27s task is only to track a desired robot path with the wand. The 3-dimensional position of the wand are measured by ultrasonic devices, the principle of which was developed for this study and is introduced in detail. In order to clarify the applicability of this method, experiments were performed with respect to a continuous-path teaching and a pick-and-place task teaching which are typical jobs of robot operators

3-D Measurement of a Human Body

This paper describes a system which enables a fast 3-dimensional profile measurement of a human body using a slit-ray projection method. One distinctive feature of this system is that a real-time video processor is employed in order to reduce the amount of image data to be processed without eliminating essential information and enable a fast measurement of the human body. Experimental results show that a calibrating method presented for the TV cameras and the slit-ray projector is convenient and enables sufficient accurate measurements

Fast Three-Dimensional Measurement Technique Using a Reference Table : Measurement of a Human Head

This paper describes a system which enables fast 3-dimensional measurementof a human head by means of a slit ray projection method. The system developed here consists of a laser slit ray projector, two CCD TV cameras, a real-time video signal processor and a 32-bit computer. Due to the employment of this real-time video signal processor and a fast data-processing technique using a reference table, a 3-dimensional measurement of the human head can be Accomplished in 4.3 seconds, and all the image data are converted to 3-dimensional data in one second. Experimental data reveal the applicability of our system
