Title: Atmega328 Based Human Following Smart Shopping Trolley 

Idea In Short:

This smart shopping trolley automatically tracks and follows a customer through store aisles using ultrasonic and infrared sensors, eliminating the need to manually push a cart.

System Description:

Traditional shopping trolleys require continuous manual effort to push and maneuver through crowded retail environments, which can be exhausting for shoppers and particularly challenging for elderly or mobility-impaired individuals. This project addresses the issue by introducing an automated, human-following smart trolley built on an Atmega328 microcontroller platform. The system combines a steel mesh basket chassis with a 4-wheel drive mechanism. Using a front-facing ultrasonic sensor, it maintains a dynamic, safe following distance behind the shopper, while bottom-mounted IR sensors provide line-following guidance along designated shopping lane tracks. By automating movement and lane navigation, the trolley delivers a seamless, hands-free shopping experience.

  2. IR Sensors (Input): Detects floor line markings along retail aisles to keep the robotic trolley centered within the designated movement lanes.

  3. Regulatory Circuitry & PCB (Power & Distribution): Converts and regulates input power to supply steady operating voltage to the microcontroller, sensors, and motor driver modules.

  4. Atmega 328 Microcontroller (Processing Unit): Receives range and trajectory inputs from the ultrasonic and IR sensors, processes navigation algorithms, and outputs precise speed/direction control signals.

  5. Motor Drivers (Power Amplification): Accepts control signals from the microcontroller and amplifies them to drive the high-current DC motors safely.

  6. DC Motors & 4WD Robot Chassis (Locomotion/Actuation): Drives four motorized wheels to move the attached wire mesh shopping basket smoothly behind the customer.

System Application:

• Autonomous customer assistance in supermarkets, hypermarkets, and shopping malls.

• Hands-free shopping support for elderly individuals or shoppers with limited physical mobility.

• Automated material or inventory transport in warehouse aisles and retail fulfillment centers.

Title: Atmega328 Based Pesticide Sprayer and Grass Cutter Spider Robotic System

Idea In Short:

This spider robot allows farmers to remotely navigate fields to precisely spray pesticides and trim unwanted grass or weeds from a safe distance of up to 5 meters.

System Description:

Traditional pesticide application methods often suffer from imprecise chemical delivery, resource waste, and potential safety hazards due to direct operator exposure. Additionally, the growth of invasive weeds typically requires separate manual labor. This project addresses both issues by integrating a remote-controlled spider robot with a pesticide spraying pump and a front-mounted grass cutter. Operating within a 5-meter wireless range, the system allows the user to safely navigate dynamic farm terrain, target specific crop areas for controlled pesticide dispersal using an onboard tank pump, and activate a high-speed weed cutter motor to slice through unwanted vegetation in a single pass.

System Details:

• Hardware Inventory:

  • Atmega 328 Controller

  • DC Motors

  • BLDC Motor

  • Pump Motor

  • Water Tank

  • Motor Drivers

  • Spider Robot Chassis

  • Gears and Joints

  • Regulatory Circuitry

  • PCB Board

  • Resistors

  • Capacitors

  • Transistors

  • Cables and Connectors

• Software Inventory:

  • Operating System: None

  • Programming Language: Embedded C / C++ (Arduino IDE)

• Working Blocks (System Process Flow):

  1. Remote Control Unit (Input): Captures wireless navigation and mechanism commands sent by the user from up to 5 meters away.

  2. Regulatory Circuitry & PCB (Power & Distribution): Regulates incoming power to feed stable voltage levels to the central processor, logic circuits, and motor drivers.

  3. Atmega 328 Microcontroller (Processing Unit): Decodes incoming control signals and executes the logical sequence required to drive the leg actuators, pump, and cutting assembly.

  4. Motor Drivers (Power Amplification): Receives low-power control signals from the microcontroller and delivers high-current output to drive the locomotion and actuation motors.

  5. Spider Chassis & DC Motors with Gears/Joints (Locomotion): Moves the multi-legged spider mechanism to navigate across uneven, dynamic field surfaces.

  6. BLDC Motor Weed Cutter (Actuation - Trimming): Powers the front cutting mechanism upon command to slice through unwanted grass and weeds.

  7. Pump Motor & Water Tank (Actuation - Dispersal): Drives liquid pesticide from the onboard storage tank through spray nozzles onto target crops.

System Application:

• Precision pesticide application without exposing farm workers to harmful chemical vapors.

• Automated weed cutting and grass management around crop rows.

• Crop maintenance in narrow, dense, or uneven agricultural terrain inaccessible to heavy machinery.
