The XR power management system provides the Nomad XR mobile robot systems with comprehensive power diagnostic and control capabilities. This system allows the robot to be powered directly from AC and also incorporates a sophisticated two stage fast battery-charging system. The current going in and out the batteries is integrated, allowing precise measurement of the charge remaining. Voltage and temperature are measured for each battery as well as providing safe and accurate determination of battery damage or end of life. Independent power control of different subsystems, knowledge of charge remaining, and the potential for self docking into an AC source allows cognitive decisions to made by the system regarding task scheduling and other mission priority issues.
Rugged energy absorbing rubber molding protect the top and bottom perimeters of sensing elements.
The Sensus 250 TM three dimensional sonar system uses 48 sonar transducers precisely positioned at different levels and angles with coordinated firing patterns to provide complete coverage from the floor to the Nomad XR's ceiling. Firing rates, blanking intervals, firing order, and timeouts can be configured to provide optimal performance in any environment. The Sensus 350 TM infrared system uses 48 transceivers positioned at the top and bottom of the Nomad XR4000. These sensors provide close-range coverage. The Sensus 350 has a very fast sampling rate, making it very useful for short-range work.
