Abstract

A method for enabling communication and collaboration between robotic device. Robotic devices exchange wireless signals to connect to one another and enter an authentication phase. After authenticating, robotic devices add new devices to a network containing all authenticated robotic devices. Robotic devices within a network may send or receive information or instructions to and from other robotic devices in the network. Robotic devices that are out of direct signal range of other robotic devices may communicate them via other robotic devices within the network that form a bridge to forward the signals to the intended target.

Claims

1. A collaborative robotic device work group comprised of a plurality of robotic devices, robotic devices having a means for transmitting and receiving instructions or information to and from other robotic devices through wireless signals, wherein robotic devices:

establish connections to other compatible robotic devices by exchanging wireless signals;

authenticate connected robotic devices to form a network of robotic devices;

maintain a database of all robotic devices in the network;

share said database with all robotic devices in the network via wireless signals; and

send and receive data to and from robotic devices in the network through signals sent directly from one robotic device to another or forwarded through any number of robotic devices to reach a target robotic device to push and pull information or instructions to and from members of the network to more efficiently complete the tasks of the group.

2. The collaborative robotic device work group of claim 1 wherein wireless signals are any of:

radio waves, bluetooth signals, and wifi signals.

3. The collaborative robotic device work group of claim 1 wherein signals may comprise any of:

information regarding the environment of a robotic device obtained from sensors or measuring tools positioned thereon;

instructions for carrying out operations; and

information regarding the status of operations of a robotic device.

4. The collaborative robotic device work group of claim 1 wherein signals further comprise one or more target robotic devices that indicate whether recipients should read the signal or forward it to one or more other robotic devices or both read and forward the signal to one or more other robotic devices.

5. The collaborative robotic device work group of claim 1 further comprising an encryption negotiation phase, occurring after authentication, in which robotic devices determine which encryption method will be used to encrypt exchanged data going forward.

6. The collaborative robotic device work group of claim 1 in which robotic devices exchange keepalive signals periodically to maintain their presence within the network.

7. The collaborative robotic device work group of claim 1 wherein robotic devices may be assigned identifying tags that associate them with subgroups of robotic devices, tags being based on any of:

a model;

a unique identifier;

a country of origin;

a manufacturer;

a firmware version;

a software version;

an operating system;

functionality; and

any other parameters of a robotic device.

8. The collaborative robotic device work group of claim 1 wherein robotic devices further store specifications regarding robotic devices in said database, specifications including any of:

location;

model;

type;

functionality;

role;

software version; and

any other characteristics of a robotic device.

9. The collaborative robotic device work group of claim 1 wherein robotic devices may be assigned rankings that control what kinds of signals may be exchanged to and from particular robotic devices.

10. The collaborative robotic device work group of claim 1 wherein robotic devices may be assigned master or slave roles that dictate how information will be shared between robotic devices.

11. The collaborative robotic device work group of claim 1 wherein robotic devices are further provided with lists of restrictions and lists of permissions that indicate what information may be and may not be shared with other robotic devices.

12. The collaborative robotic device work group of claim 1 wherein authentication is accomplished by exchanging hash codes based on a secret passcode set at manufacture or during an initial set-up phase.
