PROBLEM DEFINITION

Design a semi-automatic Welcome Bot that can assist visitors by providing a simple, interactive, and user-friendly experience. The bot should use voice input to receive visitor queries and provide appropriate guidance. It should assist visitors in identifying and selecting the required department and provide relevant information. The system should use sensors to detect the presence or movement of visitors and respond accordingly. The bot should be easy to operate, reliable, and capable of performing functions such as visitor detection, voice interaction, department selection, navigation/guidance, and automated responses to improve visitor assistance and reduce the need for manual support.

##GATHERING PERTINENT INFORMATION

QUESTIONS:

1)What exactly is the WELCOME BOT?

smart Welcome Bot that can automatically detect visitors, greet them, provide information through voice and display, understand voice inputs, guide visitors to the required department, and notify the concerned staff when necessary.

2)Can welcome bot consists display and tell the time ?

Yes, the Welcome Bot can display the current time. It can use an ESP32 microcontroller to control the time display. The time can be obtained using an RTC module or through the internet using Wi-Fi. A display such as an LCD or OLED can show the current time. The bot can update the time automatically in real time. It can also display greetings based on the time, such as “Good Morning” or “Good Evening.” This feature makes the Welcome Bot more useful, smart, and interactive for users

3)How is WELCOME BOT useful to society?

  • Makes people feel included — It gives newcomers a friendly greeting instead of making them feel like outsiders

  • Improves accessibility — It can automatically provide instructions and resources in a simple, consistent way.

  • Saves volunteers' time — Instead of people repeatedly explaining the same information, the bot can handle basic questions automatically.

  • Helps large communities — Schools, nonprofits, public-service groups, and community organizations can use it to welcome many people at once.

  • Supports different languages — A bot can provide welcome information in multiple languages, helping more people participate.
