Systems and methods to adjust actions based on latency levels
View Patent ↗Systems and methods to adjust actions based on latency levels are described. The method may be executable to determine an action being performed by a robotic device. The method may also be executable to generate data based on execution of the action to provide to a server and receive information indicative of latency attributable to communication between the robotic device and a server. The method may also determine a priority at which to provide the generated data to the server and provide the generated data to the server in an order based on the priority. When the latency is above a threshold amount, the method may identify information of the generated data having a given priority above a threshold level and provide a reduced resolution version of the identified information to the server.
