- the collaborative operation system 100 of the present embodiment includes a control system 1, a robot 7, a detection device 4, and a situation detection device 8.
- the collaborative operation system 100 of this embodiment accumulates personal behavior data of the user 5 including collaborative operation data acquired when the robot 7 and the user 5 performed collaborative operation with the collaborative operation target 6 before the collaborative operation between the robot 7 and the user 5 is performed, and generates a control model for controlling the robot 7 using the accumulated personal behavior data.
- the collaborative operation data is personal behavior data acquired while performing collaborative operation.
- the acquired personal behavior data may be only collaborative operation data, or may include other than collaborative operation data.
- the collaborative action includes, but is not limited to, at least one of, for example, conversation, work, games, and sports.
- the collaborative action target 6 is another person who performs a collaborative action with the user 5 and is familiar with the user 5 in the collaborative action.
- a person who is familiar with the user 5 in the collaborative action is, for example, a person who is not meeting the user for the first time and knows at least a little about the other person's personality or speech and behavior habits, and therefore, the user 5 feels that they are compatible in the collaborative action and is less likely to feel stressed when the user 5 performs a collaborative action together.
- the collaborative action target 6 may be determined, for example, by the user 5, or may be determined by an operator of the collaborative action system 100 other than the user 5.
- the collaborative action target 6 When determined by an operator of the collaborative action system 100, for example, a person who is clearly performing a collaborative action with the user 5 for a long period of time is determined as the collaborative action target 6.

- FIG. 7 is a schematic diagram showing an example of cooperative operation between user 5 and robot 7 in the first example.
- a control model has been generated to cause robot 7 to serve food on a large platter, and so robot 7 serves food on a large platter.

- the behavior result may be input to the control model generation unit 2b or may be transmitted from another device. If the task is performed efficiently, it can be estimated that the stress on the user 5 is low, so the behavior result may be determined based on the measurement result of the task time in this way.

- the control parameter that is estimated to be better is, for example, a control parameter that is changed in the opposite direction to the control parameter that was set when the behavior result was previously a negative result. For example, if the conversation speed is a first speed, the behavior result is negative, and changing the conversation speed to a second speed slower than the first speed results in a positive behavior result, the control model may be updated to change the conversation speed to a third speed slower than the second speed. Then, the behavior result is obtained again, and if the behavior result is negative, the control model is updated to return the conversation speed to the second speed.

- the learning unit 22b uses multiple data sets consisting of the action results and the control parameters that are the corresponding correct answer data to generate a learned model by the supervised learning described in the first embodiment. Then, at the time of inference, i.e., at the time of updating the control model, the learning unit 22b can infer control parameters that will result in a positive action result by inputting a value that will result in a positive action result as the action result.
- the behavioral result is not limited to the binary values of positive and negative, but may be expressed as a number with three or more levels.
- the behavioral result may be scored from 0 to 5, and a behavioral result of 5 may be defined as the least stressful for user 5, and a behavioral result of 0 may be defined as the most stressful for user 5.
- the definition of the score is not limited to this example.

- the behavior result was the result of evaluating the entire control model, but it is not limited to this, and may be the result of evaluating the time-series movements of the robot 7 in sections.
- the control instructions to the robot 7 may be recorded in an operation history storage unit (not shown), and the behavior result may be determined, for example, at regular intervals or for each section of the robot 7's movements.
- the operation history storage unit may be provided in the robot control unit 3, in the control model generation unit 2b, or outside the control system 1b.
- the behavior result acquisition unit 26 reads and acquires the control instructions for the period corresponding to the behavior result from the operation history storage unit together with the behavior result, and outputs the behavior result and the corresponding control instructions to the learning unit 22b. In this way, the learning unit 22b can obtain the behavior result of the movement in units of the movement of the robot 7 corresponding to the control instructions performed in the time series.
- the collaborative action is a conversation

These periods are distinguished based on a control instruction to the robot 7, and the behavior result of each is acquired by the behavior result acquisition unit 26.
- control model is updated to increase the frequency of providing topics of the first genre and decrease the frequency of providing topics of the second genre.
