Systems and methods for active suspension for a robotic cleaning device

A robotic cleaner for optimizing suction with a target surface by independently adjusting one or more ride height dimensions with respect to the target surface, the robotic cleaner comprising:

• a plurality of wheel assemblies each including:
• an arm having a first end pivotally mounted to a chassis of the robotic cleaning device and a second end opposite the first end;
• a wheel rotatably coupled to the second end of the arm, the wheel configured to contact the target surface;
• a cam in slidable contact with the arm;
• and
• a cam motor mounted to the chassis of the robotic cleaning device, the cam motor configured to selectively rotate the cam in response to one or more dimensions of the target surface;
• wherein each of the plurality of wheel assemblies is configured to independently activate a respective cam motor to push a respective second end of the respective arm away from the chassis in response to the one or more dimensions of the target surface.

A processor-implemented method of optimizing suction for a robotic cleaning device with respect to a target surface by independently adjusting one or more ride height dimensions of the robotic cleaning device, the method comprising processor-executable instructions for:

• sensing, via one or more sensors, one or more characteristics of an environment surrounding the robotic cleaning device;
• identifying, via one or more processors and based on the one or more sensed characteristics, an object in the environment;
• determining, via the one or more processors, that the object is located in a path of the robotic cleaning device;
• determining, via the one or more processors and based on the sensed one or more characteristics, at least one dimension of the object;
• and
• activating an active suspension system of the robotic cleaning device to raise the distance between a chassis of the robotic cleaning device and the target surface based on the determined at least one dimension.
