Abstract: A track-wheel based device is disclosed. The track-wheel based device may include a longitudinal member substantially perpendicular to an axis of motion of the track-wheel based device. The track-wheel based device may further include a first lateral member and a second lateral member, each being substantially parallel to the axis of motion of the track-wheel based device. The longitudinal member may be coupled to the first lateral member at a first location of the first lateral member and to the second lateral member at a first location of the second lateral member. The first lateral member and the second lateral member may be configured to undergo a relative angular rotation, in response to a planar misalignment of four or more points of contact between two or more guide tracks for the track-wheel based device and the track-wheel based device.

Abstract: This disclosure relates to system and method for docking or undocking a track-wheel based device. In some embodiments, the system may include a docking station configured to be fitted on a support track for the track-wheel based device. The docking station may include a protrusion to be fitted at a first position on the support track. The protrusion may be configured to make the track-wheel slide on the support track against the protrusion until an indentation on the track-wheel engages with the protrusion upon alignment. The system may further include an end-dock to be fitted at a second position on the support track. A segment of the support track between the first position and the second position is configured to accommodate the track-wheel during docking.

Abstract: This disclosure relates to system for stabilizing a track-wheel based device is disclosed. In some embodiments, the system may include a support track configured to support the track-wheel based device. The system may further include a support-finger coupled to the track-wheel based device via a pivot point, the support-finger being rotatable about the pivot point between a first position and a second position. In the first position, the support-finger may be configured to sandwich the support track between the track-wheel based device and the support-finger. The system may further include a biasing member having a first end and second end. The biasing member may be coupled to the at least one support-finger via the first end, and to the track-wheel based device via the second end. Further, the biasing member may be configured to maintain the at least one support-finger biased in the first position.

Abstract: A telescopic guide assembly for bridging a first solar panel table and a second solar panel table is disclosed. The telescopic guide assembly may include an inner pipe partially disposed within an outer pipe. The inner pipe may be configured to rotate within the outer pipe and may be further configured to partially slide-in or slide-out of the outer pipe. The telescopic guide assembly may further include a first coupler configured to mechanically couple the inner pipe with the first solar panel table at an associated first position on an inner side of the first solar panel table facing a second solar panel table, and a second coupler configured to mechanically couple the outer pipe with the second solar panel table at an associated second position on an inner side of the second solar panel table facing the first solar panel table.

Abstract: Cleaning system including a brush assembly for cleaning solar panels. The brush assembly has at least one rotatable brush having a rotational axis. The rotatable brush includes a plurality of sets of bristles, each extending outwardly from a core. A shaft extends through the core of the brush. The shaft is a telescoping shaft, which is configured to retract and expand to create an elongated brush assembly. An apparatus, system, and method for conveying an assembly along a track. A rail includes a first planar side, a second planar side, and a third planar side. The first, second and third planar sides are arranged to form at least two acute angles ranging between 50 degrees and 80 degrees. A carriage assembly includes a drive wheel and at least two rollers. The drive wheel is configured to contact the second planar side and is configured to translate the assembly along the rail. The two rollers are configured to contact the two other sides to maintain the carriage in contact with the rail.
