A practical look at latency in robotics: the importance of metrics and operating systems

Latency is an important practical concern in the robotics world that is often poorly understood. We feel that a better understanding of latency can help robotics researchers and engineers make design and architecture decisions that greatly streamline and accelerate the R&D process. We’ve spent many hours looking for information on the latency characteristics of various robotic components, but have had difficulty finding anything that is clearly presented or backed by solid data. From what we’ve found, most benchmarks focus on the maximum throughput and either ignore the subject of latency or measure it incorrectly.
