Social robotics research requires the replicability of the experiments used to validate new technical or scientific claims. However, humans behavior is difficult to replicate. We have designed and implemented a system to simulate interactive agents that can be perceived by a robot in a robotic simulator. These agents can exhibit social behaviour in human group movement, for example, by talking face-to-face. These humans are interactive with the robot and can be perceived so that the robot can react to their behavior. The humans can be choreographed to create high-level social behaviours such as waiting for an elevator, getting in and out of it, or standing in front of a store window and moving together to the next one. The tool would provide metrics to evaluate the robot's performance in defined social situations.
