Abstract

A path planning method for a robotic floor-cleaning device in which a user'"'"'s commands are repeated autonomously by the robotic floor-cleaning device at a later time.

Claims

1. A path planning method for a robotic floor-cleaning device comprising:

in a first step, receiving by a robotic floor-cleaning device a sequence of one or more commands from a user via an input device;

in a second step, executing the sequence of commands;

in a third step, saving the sequence of commands in a memory unit after a predetermined amount of time from receiving a most recent command; and

,

in a fourth step, re-executing the sequence of commands.

2. The path planning method of claim 1, wherein the fourth step is only carried out if a prompt is accepted by a user via the input device.

3. The path planning method of claim 1 further comprising associating the sequence of commands with a location at which the robotic floor-cleaning device was located when the sequence was received and carrying out the fourth step when the robotic floor-cleaning device is at that location anew.

4. The path planning method of claim 1 wherein the input device is any of a remote control, a user interface on the robotic floor-cleaning device, a software interface on a computer, a software interface on a smartphone, and a software interface on a tablet.

5. A method for navigating a robotic floor-cleaning device comprising:

in a first step, receiving by a robotic floor-cleaning device a sequence of one or more navigation commands from a user via an input device;

in a second step, executing the sequence of navigation commands;

in a third step, saving the sequence of navigation commands in a memory unit after a predetermined amount of time from receiving a most recent command; and

,

in a fourth step, re-executing the sequence of navigation commands.

6. The navigation method of claim 5, wherein the fourth step is only carried out if a prompt is accepted by a user via the input device.

7. The navigation method of claim 5 further comprising associating the sequence of navigation commands with a location at which the robotic floor-cleaning device was located when the sequence was received and carrying out the fourth step when the robotic floor-cleaning device is at that location anew.

8. The navigation method of claim 5 wherein the input device is any of a remote control, a user interface on the robotic floor-cleaning device, a software interface on a computer, a software interface on a smartphone, and a software interface on a tablet.
