Technique for providing reliable control in a cloud robotics system

A method for providing reliable control of a robot in a cloud robotics system, the method being performed by a computing circuit configured to conceal delayed or lost commands sent to the robot by a robot controller in the cloud robotics system, the method comprising the computing circuit:

• detecting a missing command expected to be received by the robot from the robot controller, the missing command detected based on a delay or loss of the command in a communication path between the robot and the robot controller;
• generating a substitutional command corresponding to an expected instruction of the missing command by
• generating the substitutional command based on one or more sensor values sent from the robot to the robot controller,
• wherein the one or more sensor values are used to determine a predicted continuous control command value, and
• wherein the substitutional command is generated based on the predicted continuous control command value;
• sending the substitutional command to the robot;
• and
• initiating a safety stop of the robot when a duration of the delay or loss of the missing command exceeds a predetermined time limit.

A non-transitory computer readable recording medium storing a computer program product for controlling a computing circuit for providing reliable control of a robot in a cloud robotics system, the computing circuit configured to conceal delayed or lost commands sent to the robot by a robot controller in the cloud robotics system, the computer program product comprising program instructions which, when run on processing circuitry of the computing circuit, causes the computing circuit to:

• detect a missing command expected to be received by the robot from the robot controller, the missing command detected based on a delay or loss of the command in a communication path between the robot and the robot controller;
• generate a substitutional command corresponding to an expected instruction of the missing command by
• generating the substitutional command based on one or more sensor values sent from the robot to the robot controller,
• wherein the one or more sensor values are used to determine a predicted continuous control command value, and
• wherein the substitutional command is generated based on the predicted continuous control command value;
• send the substitutional command to the robot;
• and
• initiate a safety stop of the robot when a duration of the delay or loss of the missing command exceeds a predetermined time limit.
