Problems solved by technology

For example, when a user's finger is inserted into the space between the touchpad and the ground plane of the sensing device where electric field lines flow (e.g., above the touchpad), the capacitance (Cf) may increase due to dielectric effects

Embodiment Construction

[0054] Some of the embodiments described herein may arise from the recognition that a mobile robot including a user interface on its outer surface may be susceptible to detecting inadvertent inputs as it navigates an operating environment. For example, for a mobile robot that includes a user interface with capacitive sensors as input elements, large conductors in the mobile robot's operating environment (e.g., metal furniture, metal plates, or furniture supports, etc.) reference while acting as an additional external capacitor. Wet surfaces or charged surfaces (eg, due to static electricity) may also manifest as increased capacitance. This increased capacitance can be detected at the touchpad of a capacitive sensor and, if high enough, can trigger the detection of an unintended (here also referred to as "spurious") input to the capacitive sensor, which can be critical for the operation of a mobile robot. problematic. For example, an unintended input detected in an input elem...

Abstract

A mobile robot includes a recessed well in a top surface of the mobile robot, at least one capacitive sensor underlying the recessed well and having a first region and a second region, one or more mobility sensors, and a controller coupled to the at least one capacitive sensor and the one or more mobility sensors. The controller is configured to determine an operating status of the mobile robot responsive to output signals from the one or more mobility sensors, and selectively disregard an input at a first portion of the recessed well corresponding to the first region of the at least one capacitive sensor based on the operating status of the mobile robot.

Description

[0001] priority application [0002] This application is a continuation of, and claims priority from, US Patent Application 16 / 121,048 filed September 4, 2018, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present disclosure relates to mobile robots, and more particularly, to a user interface for a mobile robot and a mobile robot including the user interface. Background technique [0004] A mobile robot, such as a mobile cleaning robot, may include a user interface on one or more surfaces thereof. The user interface may allow local user interaction or control of the mobile robot by directly inputting operational instructions or commands via the user interface. Some user interfaces may include input elements in the form of physical and / or virtual buttons on which frequently used operating instructions or commands are displayed. For example, a user interface for a mobile cleaning robot may include "clean" and "home...
