Bathroom cleaning robot

A robot configured to clean an indoor region autonomously, the robot comprising:

• a main body having a main outer housing containing a plurality of internal components configured to facilitate autonomous cleaning within an indoor region;
• a mobility module coupled to the main body and configured to move the robot autonomously across a floor within the indoor region;
• a robotic arm having a fixed end coupled to the main body or the mobility module and a movable end configured to move through multiple degrees of freedom relative to the fixed end, wherein the robotic arm is configured to facilitate autonomous cleaning within the indoor region;
• one or more cleaning tools configured to be manipulated by the robotic arm to perform a cleaning function within the indoor region;
• and
• a door opening module configured to pull open a closed spring-loaded door autonomously and hold open the spring-loaded door autonomously while the mobility module moves the robotic cleaning device autonomously through the open spring-loaded door, wherein the door opening module includes the robotic arm and an extendable foot arrangement, the robot arm being configured to actuate a door lever or doorknob of the spring-loaded door and pull open the spring-loaded door and the extendable foot arrangement being configured to automatically extend from the robot, pivot behind the spring-loaded door while the spring-loaded door is open, contact a surface of the spring-loaded door on the other side of the robot, and hold open the spring-loaded door while the mobility module moves the robot through the open spring-loaded door from a region outside of the indoor region to be cleaned into the indoor region.

A method of cleaning an indoor region using an autonomously functioning cleaning robot, the method comprising:

• performing automatically by the cleaning robot a first cleaning function within an indoor region using a first cleaning tool, wherein the first cleaning tool is removably coupled to a robotic arm of the cleaning robot;
• placing automatically by the robotic arm the first cleaning tool onto a first docking location located on the cleaning robot;
• uncoupling automatically the first cleaning tool from the robotic arm while the first cleaning tool is placed onto the first docking station;
• coupling automatically the robotic arm to a second cleaning tool while the second cleaning tool is located at a second docking location located on the cleaning robot, wherein the second cleaning tool is configured to facilitate the performance of a second cleaning function that is different than the first cleaning function;
• removing automatically by the robotic arm the second cleaning tool from the second docking location while the second cleaning tool is coupled to the robotic arm;
• performing automatically by the cleaning robot the second cleaning function using the second cleaning tool, wherein the automatic coupling and automatic uncoupling both utilize a tool change module configured to facilitate separately coupling and uncoupling the robotic arm to both of the first and second cleaning tools;
• moving automatically the cleaning robot across a floor of a region outside of the indoor region using a mobility module of the cleaning robot;
• opening automatically a closed spring-loaded door using a door opening module of the cleaning robot, wherein the door opening module includes an extendable foot arrangement configured to automatically extend from the cleaning robot, pivot behind the spring-loaded door while the spring-loaded door is open, and contact a surface of the spring-loaded door on the other side the cleaning robot;
• holding open automatically the spring-loaded hinged door using the extended foot arrangement as the extended foot arrangement contacts the door surface;
• and
• moving automatically the cleaning robot through the open door using the mobility module while the door opening module holds open the door.
