Abstract

Devices and methods for a low latency data telecommunication system and method for video, audio control data and other data for use with one or more robots and remote controls are disclosed. The data transmission can be digital. The data telecommunication system can enable the use of multiple robots and multiple remote controls in the same location with encrypted data transmission.

Claims

1. A video and/or audio wireless data transmission system comprising:

a first robot configured to wirelessly transmit a first data stream on a first frequency;

a second robot configured to wirelessly transmit a second data stream on the first frequency;

a first remote control unit configured to receive the first data stream.

2. The system of claim 1, wherein the first remote control unit is configured to receive the second data stream.

3. The system of claim 1, further comprising a second remote control unit configured to receive the second data stream.

4. The system of claim 1, wherein the first remote control unit is within a broadcast range of the first data stream and a broadcast range of the second data stream.

5. A video and/or audio wireless data transmission system comprising:

a first robot; and

a first remote control unit;

wherein the first robot is configured to wirelessly transmit video data over a digital data link with the first remote control unit.

6. The system of claim 5, wherein the first robot is configured to wirelessly transmit audio data over the digital data link with the first remote control unit.

7. The system of claim 5, wherein the first robot is configured to encrypt the transmission of video data.

8. The system of claim 7, wherein the first remote control unit is configured to unencrypt the transmission of video data.

9. A video and/or audio wireless data transmission system comprising:

a first robot; and

first remote control unit;

wherein the first robot is configured to wirelessly transmit video data to the first remote control unit, wherein the first remote control unit is configured to display the video data from the first robot comprising a split-screen and/or picture-in-picture display.

10. A video and/or audio wireless data transmission system comprising:

a first robot configured to broadcast a data signal, the first robot comprising an expandable bus (e.g., USB) configured to receive more than one input device;

a first input device connected to the expandable bus; and

a second input device connected to the expandable bus.

11. The system of claim 10, wherein the first input device comprises a first camera.

12. The system of claim 10, wherein the first input device comprises a chemical sensor.

13. The system of claim 10, wherein the first input device comprises an environmental sensor.

14. The system of claim 11, wherein the second input device comprises a second camera.

15. A video and/or audio wireless data transmission system comprising:

a robot configured to wirelessly transmit digital video data as a sequence of packets; and

a remote control configured to receive the video data and

wherein the packets comprise at least one of pixel packets or line-by-line packets.

16. A video and/or audio wireless data transmission system comprising:

a robot configured to compress and wirelessly transmit data, wherein the robot is configured to vary the quality of the compression.

17. The system of claim 16, wherein the robot is configured to reduce the compression when the transmission is in a low latency state, and wherein the robot is configured to increase the compression when the transmission is in a high latency state.

18. A video and/or audio wireless data transmission system comprising:

a robot configured to wirelessly transmit video data, wherein the robot is configured to vary a frame rate of the video data during transmission.

19. The system of claim 18, wherein the robot is configured to increase the frame rate when the transmission is in a low latency state, and wherein the robot is configured to reduce the compression when the transmission is in a high latency state.

20. The system of claim 18, wherein the robot is configured to increase the frame rate when the robot is in a fast motion state, and wherein the robot is configured to reduce the compression when the robot is in a slow or no motion state.

21. The system of claim 20, wherein the motion state of the robot correlates to the speed. and/or rate of rotation of the robot.

22. A video and/or audio wireless data transmission system comprising:

a robot configured to wirelessly transmit video data, wherein the robot comprises video encoding hardware and a USB hub, and wherein the robot is configured so the video encoding hardware sends the video data to the USB hub.

23. A video and/or audio wireless data transmission system comprising:

a robot configured to wirelessly transmit video data, wherein the robot is configured to drop frames that are not properly transmitted.
