Title: ARM Cortex Based Accurate Speed Control of Electric Car System

Idea In Short:

This project allows a user to precisely control the speed and direction of a four-motor electric vehicle wirelessly via an Android application using Bluetooth.

System Description:

Traditional vehicles rely on mechanical gearing systems for speed regulation and differential mechanisms for turning, which can add weight and complexity. This project addresses these challenges by implementing an ARM Cortex processor to control a four-motor drive electric vehicle without a conventional gearbox. The user sends direction and speed inputs from an Android device over a Bluetooth connection. The ARM microcontroller decodes these commands and dynamically adjusts pulse-width modulation (PWM) signals to each individual motor. This enables precise speed control, smooth acceleration, and synchronized RPM wheel adjustments for seamless turning in tight urban environments, all while operating as a zero-emission electric system.

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.

System Details:

• Hardware Inventory:

  • Atmega 328 Controller

  • IR Sensors

  • Ultrasonic Sensor

  • Motor Drivers

  • DC Motors

  • Robot Chassis

  • 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. Ultrasonic Distance Sensor (Input): Continuously measures the real-time distance between the trolley and the customer walking ahead to signal movement or stopping.

  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.
