Control apparatus and method for master-slave robot, master-slave robot, control program, and integrated electronic circuit

摘要

A control apparatus for a master-slave robot includes a force correction section detecting unit that detects a section at which force information from at least one of force information and speed information is corrected, and a force correcting unit that corrects the force information at a section detected as a force correction section by the force correction section detecting unit. A small external force applied to a slave manipulator is magnified and transmitted to a master manipulator, or an excessive manipulation force applied to the master manipulator is reduced and transmitted to the slave manipulator.

主权项

1. A control apparatus for a master-slave robot having a slave manipulator that grips an object and performs a task while touching an object to be worked, and a master manipulator that causes a person to remote-control the slave manipulator, the control apparatus comprising:
a master force information acquiring unit that acquires, at predetermined time intervals, force information applied to the master manipulator by the person; a speed information acquiring unit that acquires, as the predetermined time intervals, speed information of a hand of the slave manipulator; a slave force correction section detecting unit that detects a force correction section serving as information of a zone that is required to be corrected in the force information on basis of the force information acquired by the master force information acquiring unit at the predetermined time intervals and the speed information acquired by the speed information acquiring unit at the predetermined time intervals, the zone being from (i) a point in time at which a displacement between adjacent pieces of the force information exceeds a force threshold value to a point of time at which a displacement between adjacent pieces of the force information is equal to or less than the force threshold value or (ii) a point in time at which a displacement between adjacent pieces of the speed information exceeds a speed threshold value to a point of time at which a displacement between adjacent pieces of the speed information is equal to or less than the speed threshold value; a slave force correcting unit that corrects the force information in the zone detected by the slave force correction section detecting unit; a slave force transmitting unit that transmits the force information from the slave force correcting unit to the slave manipulator; a master control unit that controls manipulation information of the master manipulator when the person manipulates the master manipulator on basis of the force information from the slave force transmitting unit; and a slave control unit that is connected to the slave manipulator and the master control unit and outputs a control signal transmitting the manipulation information of the master manipulator sent from the master control unit to the slave manipulator.
