Final Project

My favorite activity is sleeping. I often turn off my alarm to keep sleeping, but because of that, I sometimes arrive late to places. That is why I wanted to make an alarm for my project that would be harder for me to turn off, so I thought of an alarm that tries to escape.

My boyfriend always says I am like a hamster (small and easily scared), so I thought I would love for my project to be shaped like a hamster to make it funny.

I think I could do the electronics with a Xiao, use molds to make the hamster shape, and laser cutting for the internal structure, as well as 3D printing. I also want to make an interface to set the alarms.

This is a bit of what I think I could do, but as I advance in the Fab path, I will clarify my ideas.

Systems integrating my project:

• Motion System: Includes the motors and drivers to allow movement through the environment.
• Navigation System: I will place sensors so that it tries to flee from the user.
• Control System: A clock sensor and a microcontroller to read the time to activate the alarm.
• Structure: Includes the design and 3D printing of the hamster shape.

Plan for the next weeks:

• Computer-Aided Design: Design the 3D model of the hamster and the internal structure.
• Computer-Controlled Cutting: Prototype the internal structure using MDF to test the fit of the components.
• Electronics Design/Production: Design a PCB for the Xiao that connects the motor drivers and sensors.
• Molding and Casting: Create the final exterior "skin" of the hamster (likely using silicone or resin for a soft finish).
• Input Devices: Add sensors so the hamster tries to run away.
• Output Devices: Control the DC motors for the wheels and the buzzer for the alarm sound.
• Interface and Application Programming: Build a simple web or mobile interface to connect to the Xiao and configure the alarm time.
