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.
Claims28
A robot comprising:
- a body movable relative to a surface;
- one or more measurement devices within the body to output information indicative of an initial orientation of the robot at an initial location of the robot on the surface;
- and
- a controller within the body to determine the initial orientation based on the information, and to control movement of the robot within an area of the surface by,
- while the robot is at the initial location and in the initial orientation, defining a virtual barrier corresponding to a line that extends across a width of the robot and beyond a first lateral side and a second lateral side of the robot, an orientation of the line being based on the initial orientation of the robot and a location of the line being based on the initial location of the robot, and
- restricting movement of the robot beyond the barrier.

- one or more measurement devices within the body to output information indicative of an initial orientation of the robot at an initial location of the robot on the surface;
- and
- a controller within the body to determine the initial orientation based on the information, and to control movement of the robot within an area of the surface by
- defining a virtual barrier when the robot is positioned at the initial location, the barrier extending along a first line parallel to a back of the robot and being based on the initial orientation of the robot and the initial location of the robot,
- illuminating a visual indicator of the robot aligned with a second line parallel to the first line, and
- restricting movement of the robot beyond the barrier.
