Behavioral Persistence and Incomplete Functional Transfer of Co-evolved Communication in Evolutionary Robotics
Co-evolved robot communication transferred from 2D simulation to 3D hardware only partially, without weight retraining.
The study transfers a co-evolved communication protocol from a 2D simulation to a 3D physical setting without retraining network weights. Two e-puck-type robots, controlled by a residual GRU, perform a food-seeking task with social signaling. After three sensory-motor corrections, including hunger-term calibration from residual-weight asymmetry, transfer remained partial: one agent reached food in 1 of 30 seeds and the other in none. Adding directional information changed some trajectories but still did not let the second agent reach the food.
- Protocol moved from 2D simulation to 3D hardware without retraining.
- Two residual-GRU e-puck robots did a food-seeking signaling task.
- One agent reached food in 1 of 30 seeds; the other never did.
- Directional social cues improved some trajectories but not joint success.
- Authors say ecological and navigational conditions must be preserved.

This work evaluates the direct transfer of a co-evolved communication protocol from a 2D simulation to a 3D physical environment, without retraining the network weights. Two e-puck-type robots, controlled by a GRU network with residual connection, were evaluated in a food-seeking task with social signaling.
