The robot controller includes: an acquisitor acquiring a prescribed detection range from a detection device detecting the human present in the detection range; a range determinator determining whether the detection range acquired by the acquisitor includes a set range set for a collaborative robot collaborating with the human so as to include a predetermined range regarding the robot; a speed determinator determining a magnitude relationship between an operating speed of the collaborative robot and a first speed; and a collaborative state determinator determining whether the collaborative robot is in either the collaborative state of being operable with the human or the non-collaborative state of not being operable therewith when the human enters the predetermined range, based on determination results of the range determinator and speed determinator. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000000351 Published 2026-09-15T19:02:46.868841Z https://opentechnical.org/p/OT-2026-000000351
