How Do You Track Robotics Performance?

We track whatever that is possible to track. So like we do analytics and data back end that allow us to get very fine growing understanding of almost all of the performance metrics that we care about. We don't have a return rate written any of our contract yet, but it might like that might might happen in the future. But what we have found typically when you compare a covering power robotic systems versus a fully manual station, we are typically able to collect a whole lot more visibility into the ongoing performance of the system.
