Coding can contribute to robot design by suggesting behavioral benchmarks. These, however, depend on the level of analysis. In illustration, semi-formalized rules are used to investigate child-robot encounters. By using behavior-level codes, we extract information about how children use the robot. This leads to findings about longitudinal changes in how children evaluate its behaviors. Children, we find, use the robot as a social mediator - to prompt synchronized social events. By focusing on a behavioral level, coding can benefit designers of robots, software and sensors
