Get inspired by a Vietnamese television series, i will create a project of mobile robot that can comunicate like an AI and control devices in your house
- Raspberrypi 4
- Max9835A Speaker Module
- INMP441 Micro Module
- Arduino Uno
- GA25 12v DC motor
- Lipo battery
- LM2596 buck module dc-dc
- XL4015 buck module dc-dc

- AI Model: local ai from olama with modek qwen2.5, version: 1.5b
- Devices Communication Protocol: MQTT
- Week1 (start: 1/4/2026): Can communicate as a child and can separate the request of communication and control device.
- Week2 (start: 1/12/2026): Can update news and weather in a location
- Week3 (start: 1/19/2026): Complete the hardware assembly, web server control interface and imtegrate cammera with raspberrypi.
- Week4 (start: 1/26/2026): Updated motors moving control and combine camera tracking with motors
- Week5 (start: 2/2/2026): Updated system start automantically when rasperrypi turned on and remember system log for control page
- Face recognition and Robot interaction
