A Comprehensive Guide to the Materials and Components of a Smart Autonomous Robotic A

In an era where technology is rapidly evolving, businesses are constantly seeking innovative ways to engage with consumers.

Meet SARA—the Smart Autonomous Robotic Advertiser. This groundbreaking Autonomous Mobile Robot (AMR) is designed to revolutionize the advertising industry. Equipped with a state-of-the-art perception system, SARA can detect the gender and age of individuals in its vicinity and display targeted advertisements accordingly. But that's not all; SARA also has the capability to autonomously navigate to stores it is advertising for, making it a truly autonomous advertising solution.

In this blog post, we will delve into the essential systems that will be available in SARA and make it a game-changer in the world of advertising.


Essential Materials and Components


1. Power System

Materials: High-capacity and lightweight batteries like lithium-ion.

SARA's power system is its heartbeat. At its core lie the robust lithium-ion batteries, celebrated for their long-lasting performance and energy efficiency. These batteries guarantee that SARA can function for extended durations without the need for frequent recharges.


2. Navigation System

Materials: LiDAR sensors, encoders, inertial measurement units (IMUs), and ultrasonic sensors.

To traverse intricate environments, SARA boasts a top-tier navigation system. Position feedback is essential for the SLAM and Navigation phase, it is ensured by the motors' encoders. It is complemented by LiDAR sensors that scan the environment and detect the surrounding obstacles. IMUs monitor SARA's orientation and trajectory, and ultrasonic sensors act as a protective shield, detecting and avoiding obstacles.


3. Perception System

Materials: High-resolution cameras, and machine learning processors.

SARA's perception system serves as its primary visual interface. The high-resolution cameras equipped in SARA are designed to capture the finest details of their surroundings, ensuring that every visual input is sharp and clear. These cameras are not just for passive observation; they're actively integrated with advanced machine-learning processors. These processors are trained on vast datasets, enabling them to detect faces within the camera's field of view. Once a face is detected, the machine learning algorithms work meticulously to recognize specific features, determining the gender and approximating the age of the individual. This combination of high-definition imaging and intelligent processing allows SARA to interact with its environment and audience in a personalized and informed manner.


4. Driving System

Materials: Brushless DC motors, rubberized wheels, remote control.

SARA's driving system is the foundation of its mobility. The brushless DC motors equipped in SARA ensure fluid and efficient movement across diverse terrains. Paired with these motors are the rubberized wheels, which offer superior traction on multiple surfaces, ensuring SARA's consistent and safe movement. Additionally, the inclusion of a remote control elevates SARA's capabilities to a "drive-by-wire" level. This means that while SARA can operate autonomously, operators also have the option to manually control its movements and actions from a distance, providing an added layer of flexibility and precision in its operations. This remote-controlled feature ensures that SARA can be directed with precision in environments where autonomous navigation might be challenging or during specific tasks that require human intervention.


5. Display System Materials: High-resolution screen.

SARA's display system serves as its primary medium for visual communication. The high-resolution screen equipped in SARA ensures that every image, video, or text displayed is rendered in crisp and vivid detail. This clarity ensures that advertisements and messages are not only eye-catching but also effectively convey their intended information to the audience.




The provided block diagram represents a High-Level overview of the SARA robot's architecture. The architecture is divided into two main levels: the High-Level System and the Low-Level System.

1. High-Level System:

  • Navigation System: Responsible for the autonomous movement and pathfinding of the robot.

  • Perception System: Incorporates cameras and sensors to collect data and perceive the environment.

  • Display Unit: Manages the display of advertisements or information on the robot's screen.

2. Low-Level System:

  • Drive System: Controls the mechanical aspects and movement of the robot.

  • Remote Control: Control the robot manually to achieve the drive-by-wire level

The High-Level System primarily focuses on navigation, perception, and display functionalities, while the Low-Level System is crucial for the robot's movement and drive-by-wire level. The diagram visually organizes these subsystems, illustrating how they are interconnected within the SARA robot's architecture.


SARA is a big step forward in using robots for advertising. It brings together smart technology and quality materials to connect with people in a new way. With its cool features, SARA shows us a glimpse of a future where ads are more personal and interactive. Looking forward, SARA is paving the way for exciting changes in advertising.
