About this project

Smart Shopping Trolley that Follows Customer

Objective: Develop a smart shopping trolley that autonomously follows a customer using wireless tracking and obstacle avoidance.

Context: Navigating crowded supermarkets in India can be cumbersome, especially for elderly or differently-abled shoppers. A trolley that follows users can enhance convenience and accessibility in retail environments.

What you'll build: You'll assemble a motorized trolley base controlled by Arduino UNO/Nano, using IR or Bluetooth modules for wireless object tracking. Ultrasonic sensors will enable real-time obstacle detection, while embedded C programming manages motor control and following logic. The system will be tested in a simulated shopping area for reliability.

Deliverables: Functional prototype trolley, demonstration video, and a brief technical report on design and performance.

Milestones

Submit a brief outline of your planned approach, including the main components and technologies you will use for the smart shopping trolley. Clearly list the hardware and software elements you intend to integrate, and provide a timeline for each milestone.

2. Wireless tracking system implementation

5 marks 5d

Build and demonstrate a wireless tracking system that reliably detects and follows a designated customer device (e.g., RFID tag or smartphone). Submit code, hardware schematics, and a short video showing the system tracking the device within a 5-meter range.

3. Motorized trolley base construction

5 marks 5d

Construct a motorized trolley base capable of carrying standard shopping loads and controlled via electronic signals. Submit photos, a wiring diagram, and a video showing the trolley moving forward, backward, and turning on command.

4. Obstacle detection setup

5 marks 5d

Integrate and configure sensors (e.g., ultrasonic or lidar) to detect obstacles in the trolley's path. Submit sensor placement diagrams, code snippets, and a video showing the trolley stopping or rerouting when encountering obstacles.

5. Real-time following mechanism

5 marks 5d

Develop and demonstrate the real-time following mechanism, combining wireless tracking and motor control so the trolley continuously follows the customer at walking speed. Submit annotated code, system flowcharts, and a video showing the trolley maintaining a safe distance while following a moving target.

6. Testing in a simulated shopping area

15 marks 5d

Conduct and document tests of the trolley in a simulated shopping area with aisles and obstacles. Submit a test report including setup photos, performance metrics (e.g., following accuracy, obstacle avoidance), and a video of the trolley completing a typical shopping route.

7. IR Wireless Underwater Communication System

15 marks 5d

Design and implement an IR wireless communication system suitable for underwater environments. Submit circuit diagrams, code, and a video demonstrating successful data transmission between two submerged modules, including signal strength and error rate measurements.
