The Project is called "Meet & Treat" it is a robot, that welcomes the guests and dispenses or vend small gifts. When we have an event or exhibition or conference we as companies used to distribute giveaways to the guests as a cool gift to remember our brand after the event. but the problem is we didn't know any info about the guests. So here is the "Meet & Treat" robot comes to action.
The robot was inspired by the great animation movie Wall-E and the normal vending machines.
Outer enclosure using Laster Cutter.
Vending servo and spiral wires
Sliding servo for the gift drawer.

2- Describe the project idea and general features. How would it work?
A welcoming wall-e like robot that is waving at people to say hi and move his head to check on people and guests.
The LED Matrix screen on the head displays eyes & mouth moving to give expressions.
The robot has an ultrasonic sensor to detect near guests and once a guest approaches.
It will interact and say hello, ask the guest if they need a free gift on the screen, then it will ask for the phone number and once got the number it will show 2 gifts options for the guest to choose from (Candy or toy).
Then will vend the chosen gift to the guest from a small sliding drawer & ask the guest to “follow us scanning the QR” printed on the robot body and say thank you.
Phone numbers Data will be stored on SD Card.
The project will be powered by Adapter and/or power supply.
3- Sketch your project: You may use pen and paper or a simple sketching tool like Microsoft Paint or Photoshop

6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.
6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.
Minimum Features: are the least amount of features that would demonstrate the coverage of all the technical modules and their complete integration
Complete Features: are the set of features that will complete your original project objective and vision
Nice-to-have Features: are the extra set of features that will make the project cooler, yet they need extra time, effort, and/or resources to finish
