Title: Robot driving method
Inventor: SATO KENICHI
IPC: G05D3/00
Filed: 1990-01-24
Abstract: PURPOSE:To move a long length arm at high speed and high acceleration with low vibration by setting the position deviation values of both ends in the arm in the middle of movement to be almost the same. CONSTITUTION:Both ends of an arm part 1 are respectively and simultaneously driven by a motor 3, and the position deviation values of both ends of the moving arm part 1 are respectively detected. Then, gains as against respective position deviation values are corrected so that respective position deviation values become almost the same. Consequently, vibration owing to the occurrence of the bent of the arm part 1 is prevented. The position deviation values of both ends Y1 and Y2 in the moving arm part 1 are supervised and respective position gains K1 and K2 are corrected in a real time basis if a difference occurs between both position deviation values. Then, the relative position between two axes Y1 and Y2 in the middle of movement can be ensured. Thus, deviation between two axes Y1 and Y2 is eliminated and the occurrence of the stress of the arm part 1 and the occurrence of an excessive load as against the motor 3 are prevented. Then, the arm can be moved at high speed and high acceleration.

Filed: 1989-01-25
Abstract: PURPOSE:To improve the memory efficiency by securing a constitution where a subaddress signal generating circuit outputs a subaddress signal to designate a relative address of the area to receive an access among the prescribed areas of a memory specified by an address signal. CONSTITUTION:When the instruction decoded by an instruction decoding circuit 1 is equal to a read-back instruction of the address data, an address control circuit 2 controls an address signal generating circuit 6 and a subaddress signal generating circuit 7 and outputs the data on both circuits 6 and 7 to an internal bus 5. In addition, the circuit 2 controls an address data exchange circuit 4 and outputs the data sent to the bus 5 to an internal CPU bus 3. Then the circuit 2 completes an instruction if a conditional flag F sent from a memory shows an end state. In such a way, the output of a subaddress signal is possible in order to designate a relative address of the area to receive an access. Thus the memory can be addressed for each desired bit and the memory efficiency is improved.

Abstract: PURPOSE:To evade a misinput when the specific keys are operated by transmitting the push signals for a specific one or plural ones of control keys to an auto-repeat unable code generating part. CONSTITUTION:The push signal of a specific control key or plural push signals of plural control keys are sent to an auto-repeat unable code generating part 3 from a key 1.
