Abstract

A remote diagnostic system for robots including a number of at least two robots, wherein a controller of each robot of the system is locally connected to a service unit provided with local processing power, a remote service center provided with a connector server is arranged, and a communications infrastructure for transferring packets of information between a controller of a robot of the system and connector server via the service unit is arranged for performing remote monitoring and diagnostics at the remote service center, wherein the communications infrastructure uses internet and/or GPRS communication lines.

Claims32

Dependent claims

A remote diagnostic system for at least two robots, wherein each robot comprises a respective controller, the system comprising:

a plurality of service units, each of said plurality of service units connected to a respective one of the controllers,
a remote service center comprising a diagnostics engine located at said remote service center for performing diagnostics on said robot,
a connector server provided at the remote service center, which stores a code library for communication management between said connector server and each of said service units,
each of said service units comprising local processing power and capable to receive and execute code downloaded from the connector server at the remote service center and for communication with said controller,
a communications infrastructure for a communication between said service units and the connector server for transferring information for remote monitoring and diagnostics performed at said remote service center.

2 more elements

A method for remotely performing diagnostic analysis of robots, the method comprising:

performing with a plurality of service units on request from a remote service center or initiated by a condition change at the robot assigned to a respective one of said service units at least one of the steps of:
verifying to said remote service center data of the connected robot,
requesting from the remote service center a code or a script for execution at the service unit,
transferring to the remote service center a signature for getting access to the remote service center, or
checking an authorization of a code or script received from the remote service center.
