Abstract: Implementations of the disclosed subject matter provide a method of transmitting, from a mobile robot device, sound and/or at least one image captured by a sensor to a remote user device. The mobile robot device may receive at least one first control operation for the mobile robot device to move within an area via a communications network from a remote user device. An audio signal may be transmitted based on sound received at a microphone of the mobile robot device in the area. The audio signal received from the remote user device may be output at a speaker of the mobile robot device. A volume of the audio signal output by the speaker may be adjusted based on a size of the area and on an average or a median of an amplitude of frequencies in the area based on the sound received by the microphone.

Abstract: Implementations of the disclosed subject matter provide a method of moving a mobile robot within an area. The movement of the mobile robot and the emission of ultraviolet (UV) light may be stopped when a human and/or animal is determined to be within the area. Using at least one sensor, the method may be determine whether there is at least one of human identification, animal identification, motion, heat, and/or sound within the area for a predetermined period of time. When there is no human identification, animal identification, motion, heat, and/or sound within the predetermined period of time, UV light may be emitted and the drive system may be controlled to move the mobile robot within the area. When there is at least one of human identification, motion, heat, and/or sound within the predetermined period of time, a light source may be controlled to prohibit the emission of UV light.

Abstract: An electric winch has a winch drum and a winch base. The winch drum has a drive train with an electric motor. The winch base has mounting portions being configured for rotatably holding and supporting the winch drum and the drive train. The electric winch further has a liquid-based cooling system. The winch base has a foot portion in between the mounting portions. The liquid-based cooling system is a closed-loop system and is integrated in the foot portion of the electric winch base, mounting portions, and winch drum without requiring connection to further liquid-connection points.
