A technique for providing reliable control of a robot (304) in a cloud robotics system (300) is disclosed. A computing unit configured to execute a concealment component (100) for concealing delayed or lost commands sent to the robot (304) by a robot controller (302) in the cloud robotics system (300) comprises at least one processor and at least one memory, wherein the at least one memory contains instructions executable by the at least one processor such that the concealment component (100) is operable to detect a missing command expected to be received by the robot (304) from the robot controller (302), the missing command detected based on a delay or loss of the command in a communication path between the robot (304) and the robot controller (302), generate a substitutional command corresponding to an expected instruction of the missing command, and send the substitutional command to the robot (304).
