Robot controller and robot control system

A robot control system comprising:

• a collaborative robot collaborating with a human;
• an acquisitor acquiring a prescribed detection range from a detection device detecting the human present in the detection range;
• a range determinator determining whether or not the detection range acquired by the acquisitor includes a set range that is set for the collaborative robot so as to include a predetermined range regarding the collaborative 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 an operating state of the collaborative robot is either a collaborative state or a non-collaborative state in accordance with determination results of the range determinator and the speed determinator, the collaborative state being a state in which the collaborative robot is operable with the human when the human enters the predetermined range, the non-collaborative state being a state in which the collaborative robot is not operable with the human when the human enters the predetermined range,
• wherein the collaborative state determinator determines that the operating state is the collaborative state when the determination result of the range determinator is an affirmative determination that the detection range includes the set range and the speed determinator determines that the operating speed is lower than or equal to the first speed,
• wherein the speed determinator further determines a magnitude relationship between the operating speed and a second speed that is lower than the first speed, and
• wherein the collaborative state determinator determines that the operating state is the collaborative state when the speed determinator indicates that the operating speed is lower than or equal to the second speed,
• wherein the predetermined range is a predetermined collaborative range from the collaborative robot, and
• wherein the range determinator sets the set range in accordance with a time during which the operating speed is reduced from the first speed to the second speed, a third speed regarding a moving speed of the human, and the collaborative range.
