Synchronization can be a key requirement to perform coordinated actions or reach consensus in multi-robot systems. We study the effect of robot speed on the time required to achieve synchronization using pulse coupled oscillators. Each robot has an internal oscillator and the completion of oscillation cycles is signaled by means of short visual pulses. These can, in turn, be detected by other robots within their cone of vision. In this way, oscillators influence each other to attain temporal synchrony. We observe in simulation and in physical robotic experiments that synchronization can be fostered or inhibited by tuning the robot speed, leading to distinct dynamical regimes. In addition, we analyze the effect of the involved parameters on the time it takes for the system to synchronize.
