Abstract

A semi-automatic, interactive robotic system for performing and/or simulating a multi-step task includes a user interface system, a recognition system adapted to communicate with the user interface system, a control system adapted to communicate with the recognition system, and a sensor-actuator system adapted to communicate with the control system. The recognition system is configured to recognize actions taken by a user while the user operates the user interface system and to selectively instruct the control system to cause the sensor-actuator system to perform, and/or simulate, one of an automatic step, a semi-automatic step or direct step of the multi-step task based on the recognized actions and a task model of the multi-step task.

First claim

We claim:

a sensor-actuator system of a robot adapted to communicate with said control system,
wherein said recognition system is configured to recognize, based on a task model of said multi-step task, actions taken by a user while said user operates said user interface system and instruct said control system to cause said sensor-actuator system of said robot to perform a direct step of said multi-step task,
wherein said recognition system is further configured to recognize the completion of said direct step, and
wherein said recognition system is further configured to instruct said control system to cause said sensor-actuator system of said robot to perform an automatic step of said multi-step task upon completion of the direct step based on said recognized actions and said task model of said multi-step task.

2. A semi-automatic, interactive robotic system according to claim 1 , wherein said sensor-actuator system of said robot comprises a plurality of articulated arms.

5. A semi-automatic, interactive robotic system according to claim 1 , wherein said task model is a machine-learning model.

6. A semi-automatic, interactive robotic system according to claim 1 , wherein said user interface system comprises a user observation system constructed and arranged to detect and determine motion of at least one portion of said user to communicate with said recognition system to at least one of initiate or modify instructions to be provided to said control system.

7. A semi-automatic, interactive robotic system according to claim 6 , wherein said observation system comprises cameras.

8. A semi-automatic, interactive robotic system according to claim 1 , wherein said sensor-actuator system of said robot comprises a sensor system constructed and arranged to detect and determine a property of at least one portion of an object being manipulated and to communicate with said recognition system to at least one of initiate or modify instructions to be provided to said control system.

9. A semi-automatic, interactive robotic system according to claim 1 , wherein said user interface system comprises an input device adapted to permit said user to at least one of manually or verbally input commands to be communicated to said recognition system to at least one of initiate or modify instructions to be provided to said control system.

10. A semi-automatic, interactive robotic system according to claim 1 , wherein said user interface system comprises a display system configured to display information to said user concerning a step to be performed.

11. A semi-automatic, interactive robotic simulation system for simulating a multi-step task, comprising:
a user interface system;

a simulated sensor-actuator system of a robot adapted to communicate with said control system,
wherein said recognition system is configured to recognize, based on a task model of said multi-step task, actions taken by a user while said user operates said user interface system and instruct said control system to cause said simulated sensor-actuator system of said robot to simulate the performance of a direct step of said multi-step task,
wherein said recognition system is further configured to recognize the completion of said direct step, and
wherein said recognition system is further configured to instruct said control system to cause said sensor-actuator system of said robot to perform an automatic step of said multi-step task upon completion of the direct step based on said recognized actions and said task model of said multi-step task.
