摘要:
A robot performing a variety of actions is disclosed. The voice of a user picked up by a microphone is recognized by a voice recognizer. A gesture of the user picked up by a CCD is recognized by an image recognizer. A behavior decision unit decides the behavior to be taken by the robot based on the voice information provided by the voice recognizer and the image information provided by the image recognizer.
摘要:
A servo system controller which has a sequence controlling section 2 and a servo controlling section 3, employs not only a current position of a servo motor but also other servo control data or a sequencer device as comparison data, and executes a comparing process for compares whether or not respective comparison data are in respective detection ranges to then output respective comparison results, increase and variation of a response time can be prevented until the comparison results are output from the change of the comparison data. A comparing process table memory 14 is provided in the servo controlling section 3, and the comparing process is executed in synchronism with a calculation period of the servo controlling section 3, and a detection signal is output while the comparison data is within a detection range. In a machining apparatus utilizing the servo system controller, a tact time can be reduced without large increase of a cost. Also, if the increase and variation of a decision process time have an influence upon the machining precision, reduction in the machining precision can be prevented.
摘要:
A circuit (41) to provide drive voltages to a voice coil motor (VCM) (50) of a hard disk drive (10) has identical high and low side drivers (42, 44, 46, and 48) connected to the VCM (50). Each driver has an output FET (52) selectively connecting the VCM (50) to a control voltage (58). A Class-AB output pair (54 and 54′) in parallel with the output FETs (52 and 52′) provides continuous and linear Class-AB operation at the output node (60) around the crossover point, while the output FETs (52 and 52′) are kept not conducting. This approach offers extremely low level of crossover harmonic distortion. Each FET of the Class-AB pair (54 and 54′) is connected to a biasing FET (56 and 56′) to provide the desired Class-AB quiescent current. Preferably the output FET (52), quiescent current controlling FET (54), and biasing FET (56) are fully integrated.
摘要:
A method for the control of a multi-axis machine tool, in particular for the regulation of the position of the individual axes as a function of at least one other axis or external parameters. The method includes providing a coupling function for each axis so that the coupling function can be programmed by the operator of the machine tool and activating the coupling function only after all axes involved in the coupling have been referenced.
