摘要： PURPOSE:To grip even extremely small parts with appropriate gripping force and enable highly accurate positioning by providing jogging mechanism for performing the jogging control of both position and gripping force of a hand part on the basis of the detection value from a position sensor and a gripping force sensor fitted at the hand part. CONSTITUTION:Gripping force control is performed by comparing the command value supplied to jogging mechanism 16, 17 respectively provided at hand parts 8, 9 to the detection value from gripping force sensors respectively fitted at the hand parts 8, 9 and feedback-controlling the jogging mechanisms 16, 17 to regulate force applied to the gripping force control parts 13 of the hand parts 8, 9. Position control is performed by comparing the command value supplied to the jogging mechanisms 16, 17 respectively provided at the band parts 8, 9 to the detection value from position sensors 14 respectively provided at the hand parts 8, 9 and feedback-controlling the jogging mechanisms 16, 17 to regulate force applied to the position control parts 12 of the respective hand parts 8, 9 while holding the gripping force of the hand parts 8, 9 to the set value.

摘要： PURPOSE:To positively and plastically deform an object by calculating a deformation amount and a load corresponding to a peak value of output values from an output generating body being integral with the object and deforming the object by applying a larger load then the calculated value and then returning the later deformation amount to the amount corresponding to the peak value by applying a load in the reverse direction. CONSTITUTION:A fine adjusting device is composed of an object fixing plate 4, force and position sensor holding member 9, 1st and 2nd elastic members 5, 6 and strain gages 7, 8 mounted on an end of the member 9, X direction stage 12 fixed to an XY stage fixing plate 14, Y direction stage 10, motor 13 for the X direction stage 12 and motor 11 for the Y direction stage 10. Applying a load to an object 3, measurement of deformation amounts of the object 3 and output values from an output generating body 1 are repeatedly performed by gradually increasing the applied load to the object 3. A deformation amount of the object 3 and a load corresponding to a peak value of output values are calculated based on the measuring results and a larger load than the calculated load is applied to the object 3 to deform the object 3 and then the object 3 is returned to have the deformation amount corresponding to the peak value by applying a load in the reverse direction.

摘要： PURPOSE:To accurately and easily search the position of a light emitting point by obtaining a laser light emitting position where an optically induced voltage becomes maximum, and then obtaining a laser light emitting position where the optically induced current becomes maximum at the position and in the vicinity. CONSTITUTION:A lens 203, a finely moving stage 210, etc., are so finely adjusted as to radiate the light emitting face of a laser diode 204 with a laser light 202 in a microscopes or a TV camera. In this case, it is so finely adjusted as to irradiate the specific region on the light emitting face. This is because the accurate light emitting point of the laser diode is difficult to be visually detected but an alignment of certain degree by the profile of a chip can be performed. Thereafter, the stage 210 is so operated as to irradiate the position where its voltage becomes maximum with the light 202 while monitoring the optically induced electromotive force detected by a voltage/current detector 211, and the stage 210 is further so operated as to irradiate the position where the optically induced current becomes maximum with the light 202. Thus, the position of the light emitting point can be accurately searched.

摘要： PURPOSE:To simplify a robot mechanism greatly and also improve reliability remarkably by making only necessary to lower an inserting jig and give inserting force in order to fit a shaft part into a hole made in an object. CONSTITUTION:An inserting jig 14 is connected to the piston rod of a cylinder 17 and is provided with a guide hole 19 in which the shaft of a shaft part 11 is loosely fitted with a prescribed clearance so that the position of the object shaft part 11 may be restricted. When the cylinder 17 is operated to lower the jig 14, the cone- shaped tips of guide pins 18 enter the entrances of holes 9 for pins 18 and the position of a table 5 which chucks an object part is moved and corrected horizontally by the cone-shaped tips. When the jig 14 goes down lower, the shaft part 11 whose movement is restricted by the hole 19 is inserted into a hole 2.
