Robot motions can serve as a steganographic communication channel
1 reports · 1 sources
Researchers including Benjamin Chang propose a "motion communication" method: encoding arbitrary short messages (such as an agent's current intent) as noise into the actions of any pretrained policy, so that robot motion can be detected remotely by vision or motion capture. The authors claim the method does not degrade policy performance, does not rely on wireless communication, and requires no additional hardware or direct connection to the robot. The method was validated in simulation and in real-world deployment. On real robots running at 50 Hz, four robots jointly recovered an 8-bit message at a total rate of 0.8 bits/s.

- Robot Motion as a Keyed Communication Channel: Transmitting Messages via Motion Steganography
Researchers propose a "motion communication" method that encodes arbitrary short messages (such as an agent's current intent) as noise into the actions of any pre-trained policy, making robot motion detectable via remote vision or motion capture without degrading policy performance. This physical channel does not rely on wireless communication and requires no additional hardware or direct link to the robot. On real robots running at 50 Hz, four robots jointly recovered an 8-bit message at a total rate of 0.8 bits/s, with validation completed in both simulated environments and real-robot deployment.
