Autonomous shopping device

A robotic device for delivering items, comprising:

• one or more processors;
• a chassis;
• a set of wheels coupled to the chassis;
• a motor for driving the set of wheels;
• a suspension system;
• a rechargeable battery for providing power to the robotic device;
• a control system module for controlling the movement of the robotic device;
• a set of sensors;
• and
• a container within which one or more items are carried for delivery to a purchaser;
• wherein:
• the purchaser comprises a human using the robotic device for delivery services of the one or more items;
• the purchaser selects and purchases the one or more items using an application of a mobile device;
• the one or more items are separate and independent items from the robotic device and components of the robotic device;
• the one or more processors uses data captured by at least one sensor to extract features of an obstacle within an environment of the robotic device;
• the one or more processors identifies an obstacle type of the obstacle based on a comparison between the extracted features of the captured data and features of different obstacle types in a database;
• the one or more processors determines an action of the robotic device based on the obstacle type of the obstacle;
• the robotic device is stored in a designated storage location until required for delivery services;
• and
• the robotic device navigates back to the designated storage location after completing the delivery services.
