Abstract

A robotic system that includes a mobile robot linked to a plurality of remote stations. One of the remote stations includes an arbitrator that controls access to the robot. Each remote station may be assigned a priority that is used by the arbitrator to determine which station has access to the robot. The arbitrator may include notification and call back mechanisms for sending messages relating to an access request and a granting of access for a remote station.

Claims

1. A robot system, comprising:

a first mobile robot and a second mobile robot that each have a camera that can generate an image, a monitor, a speaker and a microphone that can generate audio;

a first remote station that can access said first and second mobile robots, said first remote station including a camera, a monitor that can receive said image from said first or second mobile robots, a microphone and a speaker that can produce audio provided by said first or second mobile robots; and

,

a second remote station that can access said first and second mobile robots, said second remote station including a camera, a monitor that can receive said image from said first and second mobile robots, a microphone and a speaker that can produce audio provided by said first and second mobile robots; and

,

a server coupled to said first and second mobile robots and said first and second remote stations, said server allows exclusive access to said first mobile robot by said first remote station such that said image and audio from said first mobile robot is provided to said first remote station and said image and audio are not provided to said second remote station and even though said second remote station is prevented from accessing said first mobile robot said server allows said second remote station to access said second mobile robot.

2. The system of claim 1, wherein said server includes a notification mechanism.

3. The system of claim 1, wherein said arbitrator includes a timeout mechanism.

4. The system of claim 1, wherein said arbitrator includes a queue mechanism.

5. The system of claim 1, wherein said arbitrator includes a call back mechanism.

6. The system of claim 1, wherein said second remote station can access said mobile robot, and said first and second remote stations each have a priority and said arbitrator provides robot access to said remote station with a highest priority.

7. The system of claim 6, wherein said remote stations may be given priority as a local user, a doctor, a caregiver, a family member, a service user or another mobile robot.

8. A method for controlling access to a remote controlled robot, comprising:

providing a first mobile robot and a second mobile robot that each have a monitor, a camera that can generate an image, a speaker and a microphone that can generate audio;

providing a plurality of remote stations, including a first remote station and a second remote station, each remote station including a camera, a monitor that can receive the image from the first or second mobile robots, a microphone and a speaker that can produce audio provided by the first or second mobile robots;

transmitting a request to access the [a] first mobile robot from the [a] first remote station;

allowing exclusive access to the first mobile robot by the first remote station such that the image and audio from the first mobile robot is provided to the first remote station and the image and audio are not provided to the second remote station;

transmitting a request to access the second mobile robot from the second remote station; and

,

accessing the second mobile robot by the second remote station.

9. The method of claim 8, further comprising requesting access to the first mobile robot from the second remote station and notifying the first remote station of the request.

10. The method of claim 9, wherein the second remote station creates a time interval in which the first remote station must relinquish access to the mobile robot.

11. The method of claim 9, wherein the request from the second remote station is placed in a waiting list queue.

12. The method of claim 8, further comprising transmitting a call back message from the second remote station to the first remote station to indicate the granting of access to the mobile robot.

13. The method of claim 12, wherein the mobile robot operates in either an exclusive mode or a sharing mode.

14. The method of claim 12, wherein the access request is initially transmitted to the second remote station.

15. The method of claim 12, wherein the access request is initially transmitted to the mobile robot.

16. The method of claim 8, wherein the access request includes a priority that is evaluated by the second remote station to determine access to the mobile robot.

17. The method of claim 16, wherein the remote stations may be given priority as a local user, a doctor, a caregiver, a family member, a service user or another mobile robot.
