Abstract

Robotic systems, methods of operation of robotic systems, and storage media including processor-executable instructions are disclosed herein. The system may include a robot, at least one processor in communication with the robot, and an operator interface in communication with the robot and the at least one processor. The method may include executing a first set of autonomous robot control instructions which causes a robot to autonomously perform the at least one task in an autonomous mode, and generating a second set of autonomous robot control instructions from the first set of autonomous robot control instructions and a first set of environmental sensor data received from a sensor. Execution of the second set of autonomous robot control instructions causes the robot to autonomously perform the at least one task. The method may include producing at least one signal that represents the second set of autonomous robot control instructions.

First claim

The invention claimed is:

1. A method of operation in a robotic system including a robot and at least one processor in communication with the robot, the method comprising:
receiving, by the at least one processor, a plurality of sets of robot control instructions, wherein each set of robot control instructions, as a result of execution, causes the robot to perform at least one task;
receiving, by the at least one processor, information that represents a plurality of first poses, wherein a representative first pose in the plurality of first poses is associated with a representative set of robot control instructions in the plurality of sets of robot control instructions;
receiving, by the at least one processor, information that represents a current pose of the robot relative to an item in an environment associated with the robot;
searching, by the at least one processor, for a first set of run-time robot control instructions from within the plurality of sets of robot control instructions, based on an association between the current pose and a first pose in the plurality of first poses, wherein the first pose is associated with the first set of run-time robot control instructions, and the first pose is a composite pose that is derived from a plurality of pre-recorded poses;
producing, by the at least one processor, a second set of run-time robot control instructions which, as a result of execution, causes the robot to move to the first pose following a trajectory derived by the at least one processor using interpolation; and
producing, by the at least one processor, at least one signal including information that represents the first set of run-time robot control instructions, and the first pose.

2. The method of claim 1 wherein receiving the plurality of sets of robot control instructions includes receiving a plurality of sets of piloted robot control instructions.

3. The method of claim 2 wherein the robotic system further includes an operator interface in communication with the robot, and wherein receiving the plurality of sets of robot control instructions includes:
receiving, at the at least one processor, the plurality of sets of piloted robot control instructions from the operator interface.

4. The method of claim 1 wherein receiving the plurality of sets of robot control instructions includes receiving a plurality of sets of autonomous robot control instructions.

5. The method of claim 1 comprising:
receiving, by the at least one processor, the information that represents the current pose from an input subsystem of the robot,
wherein the current pose and a representative first pose in the plurality of first poses is a relative pose with respect to the robot.

6. The method of claim 1 , comprising:
updating, by the at least one processor, at least one non-transitory tangible computer-readable storage medium with information corresponding to the at least one signal.

7. The method of claim 1 , comprising:
causing, by the at least one processor, the at least one signal to be sent through a communication channel.

8. The method of claim 1 , comprising:
in response to the execution of the first set of run-time robot control instructions by the at least one processor, causing the robot to perform at least one task.

9. The method of claim 1 , comprising:
deriving, by the at least one processor, a second set of run-time control instruction that, as a result of execution, causes the robot to move from the current pose to the first pose.

10. The method of claim 1 wherein the current pose or the first pose indicates a position for the robot and a posture for the robot.

11. A system, comprising:
a robot including a motion subsystem and a manipulation subsystem;
at least one processor communicatively coupled to the motion subsystem and the manipulation subsystem; and
at least one non-transitory processor-readable storage device communicatively coupled to the at least one processor and which stores processor-executable instructions which, as a result of execution by the at least one processor, cause the at least one processor to:
receive a plurality of sets of robot control instructions, each set of robot control instructions, as a result of execution, causes the robot to perform at least one task;
receive information that represents a plurality of first poses, wherein a representative first pose in the plurality of first poses is associated with a representative set of robot control instructions in the plurality of sets of robot control instructions;
receive information that represents a current pose of the robot relative to an item in an environment associated with the robot;
search, based on an association between the current pose and a first pose in the plurality of first poses, for a first set of run-time robot control instructions from within the plurality of sets of robot control instructions, wherein the first pose is associated with the first set of run-time robot control instructions, and the first pose is a composite pose that is derived from a plurality of pre-recorded poses;
produce a second set of run-time robot control instructions which, as a result of execution, causes the robot to move via the motion subsystem or the manipulation subsystem to the first pose, following a trajectory derived by the at least one processor using interpolation; and

produce at least one signal including information that represents the first set of run-time robot control instructions and information that represents the first pose.

12. The system of claim 11 further comprising:
an operator interface communicatively coupled to the at least one processor,
wherein a plurality of sets of piloted robot control instructions includes at least one set of piloted robot control instructions generated at the operator interface.

13. The system of claim 11 wherein a plurality of sets of piloted robot control instructions includes at least one set of autonomous robot control instructions.

14. The system of claim 11 wherein the processor-executable instructions to receive the information that represents the current pose of the item in the environment associated with the robot further include processor-executable instructions that, as a result of execution, cause the at least one processor to:
receive the information that represents the current pose from an input subsystem of the robot,
wherein the current pose and a representative first pose in the plurality of first poses is a relative pose with respect to the robot.

15. The system of claim 11 , wherein the processor-executable instructions, as a result of execution, cause the at least one processor to:
update the at least one non-transitory processor-readable storage device with information corresponding to the at least one signal.

16. The system of claim 11 , further comprising:
a communication channel communicatively coupled to the at least one processor,
wherein the processor-executable instructions, as a result of execution, cause the at least one processor to send the at least one signal to be sent through the communication channel.

17. The system of claim 11 , wherein the processor-executable instructions, as a result of execution, cause the at least one processor to:
