[0040] Robots have the advantages of precise control, safety, reliability, and flexible operation. With the popularization of robots, more and more organizations are choosing robots for precision operations. Thanks to the rapid development of 5G and Gigabit network technology, the mode of remote robot operation has gradually emerged.

[0081] The present application encodes and decodes the signal and transmits the signal data packets through multiple transmission links. If one of the transmission links fails, the signal can be transmitted through the remaining transmission links, thus providing protection for remote operation.

[0082] The signal data packet can also be divided into multiple identical signal data packets, and the signal data packets are transmitted through multiple transmission links. After the first data packet is received, the remaining data packets are deleted, providing a low-latency transmission method for signal transmission.

[0089] The operation signal data packets received by the N transmission links are all different.

[0090] Optionally, when one of the transmission links fails, the operation signal data packet transmitted through the failed transmission link may be transmitted through other normal transmission links.

[0091] S204. The first transmission device receives the operation signal data packets according to N transmission links and determines the target operation signal.

[0092] Optionally, after the first transmission device receives all the operation signal data packets, it may integrate the operation signal data packets to obtain a target operation signal data packet, and determine the target operation signal.

[0093] S205. The first transmission device sends a target operation signal to the robot through the operation signal interface, so that the robot performs the operation indicated by the target operation signal.
