# Problem
Portable robotic assistants are increasingly integrated into daily activities. However, a significant bottleneck remains: the control interfaces are often unintuitive and user-unfriendly. Most existing systems rely on abstract buttons or 2D joysticks that do not provide spatial context, leading to a steep learning curve and inefficient operation. There is a critical need for a control method that allows users to interact with robots in a more natural, spatial, and visual manner

# Solution Overview
This project aims to design and implement an Augmented Reality (AR) based smartphone-controlled robotic assistant. The project will replace traditional control schemes with an intuitive AR interface. This system will allow users to issue commands directly through the smartphone's camera view, creating a seamless bridge between human intent and robotic execution.

# Solution Components
## Subsystem 1 (Hardware)
Palm-sized Robot Chassis: A compact mobile base equipped with micro-motors and basic obstacle sensing.

Control Unit & Communication: An onboard microcontroller (e.g., ESP32) to handle real-time movement commands received via Wi-Fi/Bluetooth.

## Subsystem 2 (Software)
AR Visualization Layer: An app that overlays digital UI (path lines, status markers) onto the live robot feed.

Spatial Mapping & Interaction: Implementing "Point-to-Move" functionality where the user taps a location in the AR view to send coordinates to the robot.

# Criteria of Success
The project will be successful if the AR interface demonstrates a measurable improvement in interaction intuitiveness. Specifically:
The user can guide the robot to a target location by interacting solely with the AR smartphone interface.
The system maintains stable spatial alignment between the virtual UI and the physical robot.
The control latency is low enough to ensure real-time responsiveness.

# PROBLEM

Tea is a popular beverage but cannot be easily obtained like coffee because no machine on the market can make it as convenient to drink tea as a coffee machine. Additionally, people’s requirements for the type and strength of tea are just as complex as those for coffee. We want to design a device that allows users to input the type of tea they want to drink and their taste preferences and then receive a cup of tea that meets their requirements.”

# SOLUTION OVERVIEW

This machine has a total of five systems: an interactive subsystem that receives user input, a control subsystem that controls all other subsystems, a solid storage subsystem for storing tea leaves, a tea brewing subsystem that adds an appropriate amount of water at the right temperature, and a flavour subsystem for adding additional ingredients such as milk and sugar.

# SOLUTION COMPONENTS

##INTERACTIVE SUBSYSTEM

The interactive subsystem includes a series of digital displays and buttons for users to adjust parameters related to taste, such as tea strength, temperature, and concentration of additional ingredients. It is also capable of delivering this data to the control subsystem.

## CONTROL SUBSYSTEM

The control subsystem is capable of transmitting signals to other subsystems and can control the number of tea leaves and additional ingredients used, as well as the temperature and amount of water used, and the overall brewing time.

## TEA BREWING SUBSYSTEM

The tea brewing subsystem includes a mixing tank that can store the added tea leaves, water, and additional ingredients and can dispense the brewed tea and tea leaves together at the set time.

## FLAVOR SUBSYSTEM

The flavouring subsystem includes tanks for storing syrup and milk, as well as pipelines and valves for adding a predetermined amount of syrup and milk based on instructions from the control subsystem.

# CRITERION FOR SUCCESS

After users set their taste preferences on the front-end interface, they can wait for a certain amount of time and then enjoy a cup of tea that meets their preferences. After each tea-making process, the machine’s interior is relatively clean and there are no residual tea leaves that could affect the taste or food safety.

# DISTRIBUTION OF WORK

Zhiyuan Wang is responsible for designing the mechanical structure, including the outer shell, storage compartment, and liquid pipelines. Anyu Ying is responsible for designing and soldering the circuit board. Zhenzuo Si and Ruiqi Ye are responsible for developing and debugging the control and interaction systems.
