ROBOT SYSTEM, POSITIONAL RELATIONSHIP-ACQUIRING DEVICE, AND POSITIONAL RELATIONSHIP-ACQUIRING METHOD

摘要

[Problem] To provide a positional relationship acquiring apparatus that can acquire the positional relationship between a plurality of rotation shafts that are driven by a plurality of motors, without a user manually performing setting or the like. [Solution] A positional relationship acquiring apparatus 1 includes: a motor control unit 11 that controls a plurality of motors of a robot 2 that has a plurality of rotation shafts that are respectively driven by the plurality of motors; a receiving unit 12 that receives angular velocities that have been acquired by a plurality of angular velocity sensors that are respectively provided for the plurality of rotation shafts; and a positional relationship acquiring unit 13 that acquires a positional relationship between the plurality of rotation shafts, using the angular velocities acquired by the plurality of angular velocity sensors and received by the receiving unit 12 when the plurality of rotation shafts have been rotated by the motor control unit 11 one by one.
