BACKGROUND

Related Field

The present disclosure relates to a robotic device capable of engaging with a cleaning environment (e.g., bathtub, shower, etc.) to allow for easier cleaning of the bottom surface and at least one sidewall.

Related Art

Robotic device may be used to clean a surface in various situations. Exemplary known cleaning robotic systems may include a cleaning device configured to engage one or more surfaces. Generally, though, these known robotic devices focus one engaging the one or more surfaces via features located on only one surface (e.g., a bottom surface) thereof. Such conventional systems thus do not provide a manner for cleaning one or more differently oriented surfaces in a simultaneous manner, let alone doing so with feature positioned on a single surface. Thus, a need exists for improved robotic devices providing enhanced coverage and performance.

The sidewall drive mechanism 340 may include an assembly 341. The assembly 341 may include a housing 342, a motor 209 (FIG. 3F) positioned within the housing 342, and a small gear 343 that is coupled to the motor 209. The small gear 343 may comprise a plurality of gear teeth. At least one of the sidewall brushes 204 may be coupled, directly or indirectly (e.g., through connection rods 202), to an attachment feature 345 that extends from the housing 342. The motor 209 within the housing 342 may be configured to rotate the small gear 343. The assembly 341 may be positioned such that the gear teeth of the small gear 343 mesh with gear teeth of a large gear 344. The large gear 344 may be positioned such that a vertical center of the large gear 344 generally aligns with a vertical center of the body portion 102 of the robotic device 10. The large gear 344 may be stationary relative to the body portion 102 of the robotic device 10. The large gear 344 may be positioned upward from the rotating and oscillating mechanism 330. When the small gear 343 is rotated by the motor 209 within the housing 342, the assembly 341 may rotate circumferentially around the large gear 344. The sidewall drive mechanism 340 may oscillate the sidewall brushes 204 from the respective first linear position at the first end of the robotic device 10 to the second linear position at the second position of the robotic device 10. The sidewall drive mechanism 340 may further cause the sidewall brushes 204 to simultaneously rotate while oscillating along the opening of the robotic device 10.

Referring to FIGS. 3D-3F, schematic views of a robotic device 10 that includes a sidewall drive mechanism 340 is depicted, in accordance with an example embodiment. FIGS. 3D and 3E depict cross-sectional, top views of the robotic device 10 and FIG. 3F depicts a cross-sectional, side view of the robotic device 10. As discussed, the sidewall drive mechanism 340 may oscillate the sidewall brushes 204 along the opening 203 of the robotic device 10. The sidewall drive mechanism 340 may include a large gear 344 and at least one assembly 341, such as a first assembly 341a, that orbits around the large gear 344 (e.g., rotates circumferentially around the large gear 344). The first assembly 341a may be coupled to a first sidewall brush 204a. The sidewall drive mechanism 340 may include a second assembly 341b that may be configured similarly or the same as the first assembly, and may be coupled to a second sidewall brush 204b.

Each assembly 341 may include a connection rod 202. Each connection rod 202 may be pivotably coupled to a vertical center shaft 207 that may be positioned in a center of the robotic device 10. For example, each connection rod 202 may include at least one bearing 206a (FIG. 3F) that allows the connection rod 202 to pivot around the center shaft 207. The center shaft 207 may extend through a center of the large gear 344. The center shaft 207 and the large gear 344 may be configured to remain stationary relative to a body portion 102 of the robotic device 10.

Each assembly 341 may include a vertical distal shaft 208, which may be pivotably connected to the respective connection rod 202. For example, each connection rod 202 may include at least one bearing 206b that allows the vertical distal shaft 208 to pivot relative to the connection rod 202. Each vertical distal shaft 208 may be coupled to a motor 209, which may be an electric motor. The motor 209 may be configured to rotate the distal shaft 208. Each distal shaft 208 may be rigidly coupled to a small gear 343. As such, rotation of the distal shaft 208 by the motor 209 may cause rotation of the small gear 343.

Rotation of the small gear 343 may cause the small gear 343 to orbit around the large gear 344 (e.g., rotate circumferentially around the large gear 344). The circumferential movement of the small gear 343 may cause the vertical distal shaft 208, the motor 209, the connection rod 202, and the sidewall brush 204 to pivot around an axis defined by the center shaft 207. Stated differently, rotation of the small gear 343 may cause the respective sidewall brush 204 to oscillate along the opening 203 of the robotic device 10. For example, rotation of the small gear 343 in a clockwise direction by the motor may cause the respective sidewall brush 204 to orbit around the body portion 102 of the robotic device 10 in a clockwise direction, as denoted by arrow C in FIGS. 3D and 3E. Similarly, rotation of the small gear 343 in a counterclockwise direction by the motor may cause the respective sidewall brush 204 to orbit around the body portion 102 of the robotic device 10 in a counterclockwise direction, as denoted by arrow CC in FIGS. 3D and 3E.

As will be appreciated, each sidewall brush 204 may be controlled independently. As such, a first sidewall brush 204a may move clockwise while a second sidewall brush 204b moves counterclockwise. In various examples, a first sidewall brush 204a may move clockwise while a second sidewall brush 204b also moves clockwise. Each sidewall brush 204 may completely orbit around the body portion, such that it rotates more than 360 degrees around the body portion 102 of the robotic device 10.

Referring to FIGS. 3G-3I, schematic views of a robotic device 10 that includes a sidewall drive mechanism 340 is depicted, in accordance with an example embodiment. FIGS. 3G and 3H depict cross-sectional, top views of the robotic device 10 and FIG. 3I depicts a cross-sectional, side view of the robotic device 10. The robotic device 10 of FIGS. 3G-3I may be configured similarly to the robotic device 10FIG. 3D-DF. However, the robotic device 10 of FIGS. 3G-3I may include at least one motor 209 that is configured to rotate at least one sidewall brush 204 on an axis that extends through the at least one sidewall brush 204. For example, a motor 209 may be coupled to a distal end of each connection rod 202, which may be configured to rotate a sidewall brush shaft 210 that is coupled to, or integral with, a sidewall brush 204.

In various examples, rotation of the motor at the distal end of the connection rod 202 may cause the respective sidewall brush 204 to rotate, as denoted by arrow R in FIGS. 3G and 3H. As such, each sidewall brush 204 may rotate on its own axis, as denoted by arrow R, and may also orbit around a body portion 102 of the robotic device 10, as denoted by arrows C and CC.
