Embodiment Construction

[0030] Described herein is an example robot configured to traverse (or drive) a surface, such as a floor, carpet, turf, or other material, and perform various operations including, but not limited to, vacuuming, wet or dry Cleaning, polishing and similar operations. The movement of the example robots described herein may be limited. For example, a robot may erect virtual barriers that define boundaries that the robot cannot cross. For example, users can choose locations for virtual barriers to prevent robots from entering certain spaces. like figure 1 As shown, the robot is positioned in the bathroom, and a virtual barrier (shown as a hashed square) is created to prevent the robot from entering the bedroom. As described herein, a virtual barrier can be created by the robot itself (e.g., based on the robot's orientation and position), or by the robot in combination with one or more elements, such as a barrier that the robot can recognize as limiting the robot's ability to cr...

Abstract

A robot includes a body that is movable relative to a surface one or more measurement devices within the body to output information based on an orientation of the body at an initial location on the surface, and a controller within the body to determine an orientation of the body based on the information and to restrict movement of the body to an area by preventing movement of the body beyond a barrier that is based on the orientation of the body and the initial location.

Description

technical field [0001] This specification generally relates to constraining the motion of mobile robots. Background technique [0002] A mobile robot can maneuver around a surface defined by objects, obstacles, walls and other structures in its environment. In some cases, it may be necessary to restrict the robot's motion to specific regions of its environment. To do this, barriers can be erected to prevent robots from breaking into restricted areas. For example, beacons detectable by robots could be placed in the environment to restrict the robots from entering restricted areas. Contents of the invention [0003] An example robot can identify impassable areas of the environment even if there are no structural boundaries, such as walls, barriers, or other surfaces, that prevent access to these areas. Robots can generate virtual barriers to prevent movement into these areas. Various techniques for creating such virtual barriers are described herein. [0004] An example...
