Abstract
A robotic vehicle (10) may include a chassis supporting a storage tank in which an aqueous solution is contained, a mobility assembly operably coupled to the chassis to provide mobility for the robotic vehicle about a service area (20), a positioning module (60) configured to provide guidance for the robotic vehicle (10) during transit of the robotic vehicle (10) over the service area (20), a spray assembly (90) and control circuitry (12).
Claims21
A robotic vehicle comprising:
- a chassis supporting a storage tank in which an aqueous solution is contained;
- a mobility assembly operably coupled to the chassis to provide mobility for the robotic vehicle about a service area;
- a positioning module configured to provide guidance for the robotic vehicle during transit of the robotic vehicle over the service area;
- a spray assembly operably coupled to the storage tank to spray the aqueous solution during the transit of the robotic vehicle over the service area;
- and
- control circuitry operably coupled to the spray assembly and positioning module, the control circuitry being configured to adjust characteristics of the spray assembly or speed of the mobility assembly to control an amount of the aqueous solution applied to the service area.
3 more elements
A spray assembly for a robotic vehicle, the spray assembly comprising:
- a pump operably coupled to a storage tank in which an aqueous solution is contained;
- a nozzle operably coupled to the storage tank via the pump to generate a spray pattern for spraying the aqueous solution responsive to operation of the pump as the robotic vehicle transits a service area;
- and
- a flow controller comprising processing circuitry,
- wherein the flow controller is configured to adjust characteristics of the pump or speed of the robotic vehicle to control an amount of the aqueous solution applied to the service area.
