I got inspired by someone's finale project of Maker diploma Omnia Ismail.
I had the same idea at first but then I thought if making a robot to make students more engaging during the session and paying more attention in a fun way.
My project idea revolves around creating a smart robot named Momo, designed to enhance student engagement during learning sessions. Momo will feature an LCD screen that incorporates a randomizer, making each interaction unpredictable and exciting.
In addition to the randomizer, Momo will be equipped with a Neo Pixel for colorful visual effects and a speaker to provide responses to students' answers in a fun and dynamic way.
The playful responses, combined with the element of surprise from the randomizer, will help maintain students' attention throughout the session. This approach is intended to create an interactive learning environment where students are more focused and less likely to feel bored. By incorporating these features.
Momo aims to make learning more enjoyable and stimulating, ultimately fostering a more engaging classroom experience.

2.Body & Legs:
2.Body & Legs:
I made a front panel with legs that are intended to be attached to the main body of the structure. The legs are flared at the bottom for added stability and are integrated into the overall structure, with a central arch providing clearance.
Added some openings for the speaker, LCD screen and push buttons
Used grabcad website to get the components for mounting in the design.

Fabrication process:
took the design dxf files on RDworks to check the paprmeters and start implemntation.
added the robot name on the RDworks.
adjusted the parameters (cut - power of 40 with 45 speed) then uploaded the file on the machine and added 3mm plywood on the machine and set the origin point ,the frame and checked the focus point before cutting.
got the bow from 3axis website Bow then added it the RDworks during fabrication process.
implemented the robot body before mounting the components to make sure that the size of the taps and the design were fabricated correctly.

Components:
Components:
An LCD I2C screen can display text or graphics, while a Neo Pixel 64 RGB LED matrix creates colorful lighting effects, both controlled by Arduino for interactive projects.
A 4 Ohm, 10W speaker provides clear audio output, ideal for small projects. Paired with an MP3 module, it can play audio files like music or voice prompts, controlled by microcontrollers such as Arduino.
A Bluetooth module allows wireless communication between devices, enabling data exchange and control via smartphones, computers, or other Bluetooth-enabled devices in Arduino projects.
Breadboard allows you to easily connect electronic components without soldering.
Arduino Uno is a microcontroller board
Jumber wires Easily link different parts on a breadboard.
Building the circuit:
Building the circuit:
Used Wokwi online software for building the circuit and added most of the neo pixel, mp3 module , speaker and Bluetooth module pictures to make the circuit as following:
connected the GND and 5V pins of the Arduino to the +ve and -ve rails on the breadboard.
connected the VCC and GND of each components to the +ve and -ve rail of the breadboard.
connected the signal pin of the neo pixel to pin 5 on Arduino.
connected the SCL and SDA of the LCD screen to A4 and A5 pins on Arduino.
connected the TX and RX of the mp3 module to pin 10 and 11 on Arduino also added 10K resistor for each and two speaker terminals that are on each side of the GND terminal to the speaker.
connected the TX and RX of the Bluetooth module to the RX and TX pins of Arduino.

For powering:
For powering:
used 9v adaptor for the Arduino and connected it directly to the Arduino which supplies power to most of the components.
used 5v adaptor as an additional power source for the Neo pixel due to the high current draw of the other components.
used DC power connector to stabilize the 5V power input into the design.

I had a lot of support and help from my great instructors Menna Elbadry and Ahmed Sami as they helped in codding process of my project , designing process as Menna gave me the idea of the leg design which made it much easier to me also in the powering process of the project, also Abdelrahaman Orabi who helped me a lot in fixing the problems i faced while testing the speaker and mp3 module and the problems I faced after mounting the neo pixel and testing it. big thank you to all of them. ✨
Also one of my lovely peers Omnia Anas helped me in settling down to the features I needed to make in the project.
Fun fact the above picture of us has been taken by using my robot as mobile holder after finishing it at the last offline session 😂

9- When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this project?
on of my biggest challenges was the neo pixel as after i already tested the whole circuit twice before mounting it on the design it didn't work and almost ruined an Arduino so I asked Abdelrahaman Orabi and he exchanged my Arduino and then tried it again and then Menna told me to give the neo pixel an additional 5V power separately.
from this challenge I think we should calculate the current that each components will use so we avoid this problem by giving each component its suitable power.
