# TITLE
Intelligent robot arm

# PROBLEM
For individuals with disabilities or limited mobility, it is hard for them to perform certain or multiple taskes. Or under some circumstances, the task is repetitive and boring for human. We want to design a intelligent robot arm that help disabilities and free people from repetitive work.

# SOLUTION OVERVIEW
Our graduation project aims to conceptualize an intelligent robotic arm, proficient in executing diverse tasks through voice and visual recognition. The overarching concept involves a user verbally identifying an object on a table to the robot. The robot, upon receiving the voice command, leverages its camera system to detect the specified object and subsequently manipulate it.

In addition to these fundamental functionalities, the system is designed to interpret intricate voice instructions, such as rotating the object to specific degrees based on predefined references or following a set reference for movement. This innovative project harbors the potential to significantly benefit individuals with visual impairments in managing their daily tasks, as well as aiding those facing critical situations, such as during fires or earthquakes.

# SOLUTION COMPONENTS

# SUBSYSTEM 1
Four or five axis robotics arms

# SUBSYSEM 2

An algorithm that can control the robotics arms to move and grab things

# SUBSYSEM 3

A robotics vision system that contains a camera and an algorithm that can detect certain object and its relative position to the robotic arm

# SUBSYSTEM 4

A voice recognition system that contains a microphone and an algorithm that can recognize what objects that a person is speaking of.

# CRITERION FOR SUCCESS

1. The robotics arm is able to receive and process the relative position of an object that is sent by robotics vision system and grab the target using those information.
2. Robotics vision system is able to detect object and measure the relative position of it and feeds back to the robotics arm
3. Voice recognition system is able to recognize what objects that a person is speaking of and feed back to the robotics vision system.

Master Bus Processor

Featured Project

General Description

We will design a Master Bus Processor (MBP) for music production in home studios. The MBP will use a hybrid analog/digital approach to provide both the desirable non-linearities of analog processing and the flexibility of digital control. Our design will be less costly than other audio bus processors so that it is more accessible to our target market of home studio owners. The MBP will be unique in its low cost as well as in its incorporation of a digital hardware control system. This allows for more flexibility and more intuitive controls when compared to other products on the market.

Design Proposal

Our design would contain a core functionality with scalability in added functionality. It would be designed to fit in a 2U rack mount enclosure with distinct boards for digital and analog circuits to allow for easier unit testings and account for digital/analog interference.

The audio processing signal chain would be composed of analog processing 'blocks’--like steps in the signal chain.

The basic analog blocks we would integrate are:

Compressor/limiter modes

EQ with shelf/bell modes

Saturation with symmetrical/asymmetrical modes

Each block’s multiple modes would be controlled by a digital circuit to allow for intuitive mode selection.

The digital circuit will be responsible for:

Mode selection

Analog block sequence

DSP feedback and monitoring of each analog block (REACH GOAL)

The digital circuit will entail a series of buttons to allow the user to easily select which analog block to control and another button to allow the user to scroll between different modes and presets. Another button will allow the user to control sequence of the analog blocks. An LCD display will be used to give the user feedback of the current state of the system when scrolling and selecting particular modes.

Reach Goals

added DSP functionality such as monitoring of the analog functions

Replace Arduino boards for DSP with custom digital control boards using ATmega328 microcontrollers (same as arduino board)

Rack mounted enclosure/marketable design

System Verification

We will qualify the success of the project by how closely its processing performance matches the design intent. Since audio 'quality’ can be highly subjective, we will rely on objective metrics such as Gain Reduction (GR [dB]), Total Harmonic Distortion (THD [%]), and Noise [V] to qualify the analog processing blocks. The digital controls will be qualified by their ability to actuate the correct analog blocks consistently without causing disruptions to the signal chain or interference. Additionally, the hardware user interface will be qualified by ease of use and intuitiveness.
