Abstract
A system generates, by a first source microcontroller, a first data packet comprising a payload and a first error code, the payload indicating a safety state of a robot. The first source microcontroller transmits the data packet from the first source microcontroller to a second source microcontroller. The second source microcontroller generates a second data packet that includes the payload, the first error code and a second error code. The second source microcontroller transmits the second data packet to a sink microcontroller, wherein the sink microcontroller recovers the payload based on at least one of the first error code and the second error code.
