Abstract
A robotic vehicle (10) charging station (40) may include a charge interface configured to charge a battery (210) of a robotic vehicle (10) responsive to docking of the robotic vehicle (10) at the charging station (40), and a mixing assembly (240) configured to facilitate mixing a solid material and a liquid to form an aqueous solution for provision to a storage tank (14) of the robotic vehicle.
Claims20
A robotic vehicle charging station comprising:
- a charge interface configured to charge a battery of a robotic vehicle responsive to docking of the robotic vehicle at the charging station;
- and
- a mixing assembly configured to facilitate mixing a solid material and a liquid to form a deicing solution for provision to a storage tank of the robotic vehicle,
- wherein the mixing assembly comprises a valve assembly having a plurality of alignment states,
- wherein the alignment states include a fill alignment in which liquid from an external source is provided to the mixing assembly to be mixed with the solid material to form the deicing solution, and
- wherein the alignment states further include a mixing alignment in which the deicing solution is agitated or mixed.

A robotic vehicle charging station comprising:
- a charge interface configured to charge a battery of a robotic vehicle responsive to docking of the robotic vehicle at the charging station;
- a mix tank inside which an aqueous solution is stored prior to transfer of the aqueous solution to a storage tank of the robotic vehicle;
- a pump;
- and
- a valve assembly operably coupled to a mix tank and the pump to facilitate recirculation of the aqueous solution from a bottom of the mix tank to a top portion of the mix to prevent freezing of the aqueous solution or maintain mixing of the aqueous solution.
