Abstract
A data generation device includes: a parameter generator; and a reaction force data generator. The parameter generator generates value data based on a signal having a correlation with a driving force. The parameter generator generates velocity data based on a signal representing a response of a member driven by the driving force. The reaction force data generator generates data of a reaction force received by the member from a predetermined object based on the value data and the velocity data.

A data generation device comprising:
- a parameter generator configured to generate value data based on a signal having a correlation with a driving force and generate velocity data based on a signal representing a response of a member driven by the driving force;
- a reaction force data generator configured to generate data of a reaction force received by the member from an object based on the value data and the velocity data;
- and
- a physical property data generator configured to generate physical property data of the object by executing a recursive least squares algorithm based on the velocity data, acceleration data generated based on the signal representing the response, position data generated based on the signal representing the response, and the data of the reaction force.
A data generation system comprising a data generation device for generating data and a higher-order control device,
- wherein the data generation device comprise:
- a parameter generator configured to generate value data based on a signal having a correlation with a driving force and generate velocity data based on a signal representing a response of a member driven by the driving force;
