Abstract

The invention is a computerized mobile robot with an onboard internet web server, and a capability of establishing a first connection to a remote web browser on the internet for robotic control purposes, and a capability of establishing a second short range bi-directional digital radio connection to one or more nearby computerized digital radio equipped devices external to the robot. The short-range bi-directional digital radio connection will typically have a maximum range of about 300 feet. In a preferred embodiment, this short-range wireless digital connection will use the 2.4 gHz band and digital protocols following the IEEE 802.11, 802.15, or other digital communications protocol. By employing the proper set of external short-range digital radio devices capable of interfacing with the robot (such as sensors, mechanical actuators, appliances, and the like), a remote user on the internet may direct the robot to move within range of the external devices, discover their functionality, and send and receive commands and data to the external devices through the CGI interface on the robot'"'"'s onboard web server.

video camera, audio camera, environmental sensor, robotic arm, memory cache, automatic door, light, sprinkler, security system, audiovisual system, pet feeder, heating/air conditioning system, refrigerator, oven, dishwasher, washing machine, clothes dryer, health equipment, manufacturing equipment, or analytical equipment

5. :

The robot of claim 1, in which the telecommunications means to link the onboard web server to the Internet employ the HTTP or TCP/IP protocols.

6. :

The robot of claim 1, in which the web server sends SGML variant web pages selected from the group of HTML, XML or XHTML formats.

7. :

The robot of claim 1, in which the remote internet site is a human operated standard web browser that can read SGML variant web pages selected from the group of HTML, XML, or XHTML formats.

8. :

The robot of claim 1, in which the remote internet site is an automated computer system that processes the SGML variant web pages (selected from the group of HTML, XML, or XHTML) from the robot, and issues automatic commands to the robot.

9. :

The robot of claim 1, in which communication between the remote internet site, and the external devices local to the robot, pass through the CGI interface of the robot'"'"'s onboard web server.

10. :

The robot of claim 1, in which the external devices maintain a discoverable registry of services, and where the robot discovers the available services of the external devices through short-range bi-directional digital radio links.

11. :

The robot of claim 1, wherein the robot maintains a discoverable registry of its services, and makes this registry available to external devices through short-range bi-directional digital radio links.

12. :

The robot of claim 1, in which additional instructions for repetitive, complex, or time-sensitive tasks are downloaded from the remote internet site, and stored onboard the robot for later automatic execution.
