We are pleased to present the Smart Grabber project, a ground-breaking assistive technology designed to fulfil the needs of the elderly and people with vision impairments. The Smart Grabber, equipped with a range of sensors, wheels, a camera, and sound capabilities, provides users who are having difficulty navigating their surroundings with crucial assistance. The process of getting objects off the floor can be quite difficult and even dangerous for the elderly, especially those with back issues. In order to mitigate this danger of falls and accidents, the Smart Grabber offers a dependable method for locating and retrieving fallen objects. By promoting independence and mitigating safety concerns, the Smart Grabber enhances the quality of life for both the elderly and visually impaired individuals, empowering them to navigate their surroundings with confidence and ease.

UN SUSTAINABILITY DEVELOPMENT GOALS

Empowered and Driven:
Delivering Solutions for Global Issues

By addressing mobility and safety concerns among the elderly and visually impaired, the Smart Grabber initiative directly contributes to the Sustainable Development Goal of “Good Health and Wellbeing”.

The Smart Grabber project offers a creative way to improve accessibility for the elderly and visually impaired, which helps achieve the aim of “Reduced Inequalities”. The gadget ensures equitable access to necessary tasks, minimising inequities and fostering inclusivity in day-to-day living by resolving mobility and safety concerns.

Goal nine Industry, innovation and infrastructure because of our project involves the development of innovative technologies and infrastructure to create a solution that addresses specific needs in society.

DESIGN STORY

Challenges

``one of our major problems is writing the code that will enable the device to determine how far objects are from the device and returning it back to its starting point. another challenge we encountered was getting the Arduino Uno and Raspberry pi to communicate with each other.``

Solution

``For the communication problem we faced trying to connect the Arduino Uno to the Raspberry pi, rather than establishing a connection using the GPIO pins we went for the simpler USB connection, and this enabled our Arduino and Raspberry pi to communicate over a serial connection. We made use of a USB-B cable to connect both devices. For our device determining how far objects are from itself, we had to write the correct code so that the ultrasonic sensor can properly communicate with the Arduino, since the sensor emits wave which bounce of objects, we wrote a short code that convert the duration of the reflected waves to distance using the speed of sound (approximately 343 m/s. ``

Use Case

``USE CASE 1. 1) The user activates the Smart Grabber, prompting the ultrasonic sensor to start measuring distances. 2) The ultrasonic sensor emits ultrasonic waves, which bounce off nearby objects and return to the sensor. 3) The Arduino Uno receives the duration of the reflected waves and calculates the distance using the speed of sound (approximately 343 m/s). 3) If the distance to the object is within the predefined range, the Arduino Uno instructs the Smart Grabber to move towards the object. 4) Once the Smart Grabber reaches the object, it retrieves it and returns to its starting point. The user successfully retrieves the item without having to bend down or risk injury. USECASE 2: COMMUNICATION BETWEEN ARDUINO UNO AND RASBERRY PI 1) The Raspberry Pi sends commands to the Arduino Uno via a USB connection to control the movement of the Smart Grabber. 2) Using the USB connection, the Raspberry Pi sends commands such as ````move forward,```` ````turn left,```` or ````grab item```` to the Arduino Uno. 3) The Arduino Uno receives these commands and executes the corresponding actions, controlling the motors and servos of the Smart Grabber accordingly. 4)Additionally, the Arduino Uno sends status updates and sensor data back to the Raspberry Pi, providing real-time feedback on the Smart Grabber's operation. 5) The Raspberry Pi processes this data and displays it on a user interface, allowing the user to monitor the Smart Grabber's movements and status remotely. The user can control and monitor the Smart Grabber device from a safe distance, enhancing convenience and safety. ``

THE PROCESS

PROTOTYPE DESIGN

Our original model of the smart grabber was to help blind and old people retrieve objects from the floor without having to risk injury, our product was static and would always be stationary whilst helping users pick up items from the floor. The part of the smart grabber which held the product had a claw like shape with the camera just mounted a little bit above it. The ultrasonic sensor was situated right at front of the grabber.

Impact on the market

``The market is significantly impacted by the Smart Grabber device, especially in the assistive technology and healthcare industries. By meeting the demands of the elderly and those who are visually impaired, the Smart Grabber closes a significant gap in the market for creative and easily accessible solutions. It improves users' quality of life and encourages greater autonomy by helping them safely and independently retrieve items from the floor.

The Smart Grabber distinguishes itself in the assistive technology industry as a useful and intuitive solution that enables people with mobility or vision impairments. It differs from conventional assistance gadgets with its sophisticated features, which include wheels, a camera, and ultrasonic sensors. These characteristics provide a more complete and effective solution for daily activities.

Furthermore, the Smart Grabber has an impact on families, carers, and healthcare professionals in addition to the assistive technology industry. Its capacity to lower senior citizens' risk of falls and injuries not only enhances their wellbeing but also lessens the strain on healthcare systems and carers.

Furthermore, the Smart Grabber creates chances for joint ventures and partnerships with medical facilities, rehab centres, and neighbourhood support groups. Stakeholders can further increase the impact of the gadget on the market by incorporating it into current care programmes and services, which will improve the quality of care and support given to elderly and visually impaired people.

All things considered, the Smart Grabber is a game-changer in the market, propelling advances in assistive technology thanks to its creative design, practical features, and good effects on users' lives.``

RESULTS

FINAL PRODUCT

“First, our group carried out in-depth research to identify the unique requirements and difficulties encountered by the intended audience. The design process is guided by the research, which helps choose the right features and components.

our group then developed the general layout and features of the Smart Grabber, taking into account aspects like portability, user-friendliness, and ease of usage. Prototypes and schematics must be made in order to test various configurations and guarantee peak performance.

After the design is complete, we put the Smart Grabber together by combining parts including motors, wheels for mobility, an Arduino Uno microcontroller, Raspberry Pi, and ultrasonic sensors. Carefully designed, the arm and claw at the tip make it easier to pick up objects from the ground.

We then test every part as it is assembled to make sure it is compatible and functions as intended. Additionally, they improve the software code to allow the Arduino Uno and Raspberry Pi to communicate, as well as to regulate the arm and claw and the movement of the Smart Grabber.

Our team carried out extensive usage and safety testing following successful assembly and testing in order to find any potential problems and make the required corrections. The Smart Grabber’s functionality and user experience are enhanced by incorporating user feedback.

Eventually, the Smart Grabber is prepared for manufacturing if it satisfies all design requirements and safety regulations. We managed the production process, guaranteeing that standards are followed and quality control is maintained.

When the Smart Grabber is finished, it is introduced to the market and becomes an invaluable instrument for improving the independence and quality of life of the elderly and visually impaired. It gives them a renewed sense of dignity and autonomy in their day-to-day existence.
