Abstract: A control system for a robotic floor cleaning machine configured to perform a cleaning operation along a cleaning path can comprise a controller, and a plurality of sensors. The controller can be configured to control autonomous movement of the robotic floor cleaning machine along the cleaning path and autonomous performance of the cleaning operation. The plurality of sensors can be configured to sense a location of the robotic floor cleaning machine relative to surroundings of the robotic floor cleaning machine. At least two sensors from the plurality of sensors are configured to locate the robotic floor cleaning machine in overlapping areas of the surroundings.

Abstract: A floor cleaning machine can comprise a chassis, a cleaning mechanism, a control system, and a cleaning operation sensing system connected to the chassis. The chassis can be configured for movement along a cleaning path. The cleaning mechanism can perform a cleaning operation. The liquid system can provide liquid to the cleaning mechanism. The recovery system can recover liquid from the cleaning operation. The control system can control performance of the cleaning operation. The cleaning operation sensing system can detect a condition of the cleaning operation. The cleaning operation sensing system can comprise a water trailing detection system comprising: a frame connected to the chassis aft of the recovery system; an absorbent medium connected to the frame; and a moisture sensor in communication with the control system to alter a signal in response to moisture in the absorbent medium.

Abstract: A lay-in electrical connector having a lug body with multiple dividing walls defining multiple conductor-receiving channels, multiple lug caps each associated with one of the conductor-receiving channels, and a tang secured with the lug body. The electrical connector is free of welded joints as the tang is coupled with the lug body by a clamping force applied by binding screws of the lug caps to conductors positioned within corresponding ones of the conductor-receiving channels. The tang, including the mounting holes extending through the tang, may be formed by an extrusion process. A removable plug element is provided for holding the lug caps and/or tang in a pre-assembled relationship with the lug body prior to use.
