Abstract

A remote control station that controls a robot through a network. The remote control station transmits a robot control command that includes information to move the robot. The remote control station monitors at least one network parameter and scales the robot control command as a function of the network parameter. For example, the remote control station can monitor network latency and scale the robot control command to slow down the robot with an increase in the latency of the network. Such an approach can reduce the amount of overshoot or overcorrection by a user driving the robot.

First claim

What is claimed is:

1 . A remote control station that controls a robot with a camera, through a network, comprising:
a remote control station that includes a monitor coupled to the robot camera and transmits a robot control command that includes information to move the robot, said remote control station monitors at least one network parameter and scales said robot control command as a function of said network parameter.

2 . The remote control station of claim 1 , wherein said scaled robot control command is linearly proportional to said network parameter.

3 . The remote control station of claim 1 , wherein said network parameter includes a ping time.

4 . The remote control station of claim 1 , wherein said network parameter includes a video rate.

5 . The remote control station of claim 3 , wherein said network parameter includes a video rate.

6 . The remote control station of claim 1 , wherein said scaled robot control command is filtered with a low pass filter.

7 . The remote control station of claim 1 , wherein said scaled robot command reduces a speed of the robot with an increase in a network latency.

8 . A remote controlled robot system, comprising:
a robot that includes a camera and moves in response to a robot control command; and, a remote control station that includes a monitor and is coupled to said robot through a network, said remote control station transmits said robot control command that includes information to move said robot, said remote control station monitors at least one network parameter and scales said robot control command as a function of said network parameter.

9 . The system of claim 8 , wherein said scaled robot control command is linearly proportional to said network parameter.

10 . The system of claim 8 , wherein said network parameter includes a ping time.

11 . The system of claim 8 , wherein said network parameter includes a video rate.

12 . The system of claim 10 , wherein said network parameter includes a video rate.

13 . The system of claim 8 , wherein said scaled robot control command is filtered with a low pass filter.

14 . The system of claim 8 , wherein said scaled robot command reduces a speed of said robot with an increase in a network latency.

15 . The system of claim 8 , wherein said robot includes a monitor, speaker and microphone and said remote control station includes a camera, speaker and microphone.

16 . A method for remotely controlling a robot that has a camera, comprising:
generating a robot control command at a remote control station; monitoring at least one network parameter; scaling the robot control command based on the monitored network parameter; transmitting the scaled robot control command to a robot; and, moving the robot in accordance with the scaled robot control command.

17 . The method of claim 16 , wherein the scaled robot control command is linearly proportional to the network parameter.

18 . The method of claim 16 , wherein the network parameter includes a ping time.

19 . The method of claim 16 , wherein the network parameter includes a video rate.

20 . The method of claim 18 , wherein the network parameter includes a video rate.

21 . The method of claim 16 , further comprising filtering the scaled robot control command with a low pass filter.

22 . The method of claim 16 , wherein the scaled robot command reduces a speed of the robot with an increase in a network latency.
