A technique for providing reliable wireless communication between a robot (104) and a robot controller (102) in a cloud robotics system is disclosed. A method implementation of the technique is performed by a primary connectivity component (106) supporting multipath transmission over a plurality of wireless transmission paths to establish connectivity between the robot (104) and the robot controller (102). The method comprises triggering determining (S402) a robot sensitivity value indicating a degree of operation sensitivity of the robot (104) to a transmission failure between the robot (104) and the robot controller (102), and triggering configuring (S404) use of one or more of the plurality of wireless transmission paths for communication between the robot (104) and the robot controller (102) depending on the determined robot sensitivity value.
