They offer far greater acuity, focus, and precision than humans. For example, ASRs are capable of scanning for threats, using facial recognition and license plate identification. They are equipped with two-way communication, giving them the ability to intervene in hostile situations and reduce their intensity, effectively replacing security personnel with a robot. "The ASR's 'talk-down' function removes the danger from the human and places it on the robot," says Stacy Stephens, co-founder and director of clients at Knightscope, Inc.

The intense level of computing, communications, and sensing places a huge load on the ASR's power supply networks. The power supply must be compact and highly efficient. Cooling has a major impact on efficiency and performance. Since ASRs lack airflow and ventilation, Knightscope sought a conductive cooling solution that would utilize the robot's aluminum skin as a heat sink. They adopted a Vicor DC-DC converter module (DCM3623) for its unique ChiP (Converter housed in Package) design. It is thermally suitable and very power-dense. The DCM's power density also helps route wiring and cable assemblies, thus increasing efficiency, performance, and battery runtime. Furthermore, Vicor power modules can be connected in parallel to deliver even more power. The power modules are easily scalable and can be adapted as Knightscope innovates and enhances its ASR feature sets in future designs.
Mobile robots carry a wide variety of payloads, ranging from computers and sensor systems to motor drives and cameras. Knightscope's ASRs feature LIDAR, GPS, sonar, IMUs, 4K cameras, and high-fidelity audio, and utilize high-density Vicor power modules to power these payloads.
