Course Overview

Welcome to ECE 445/ME470 Senior Design ZJUI Spring 2022!

Welcome to the class! If you've looked at the course Calendar, you've probably already noticed that this class is quite different from most other classes in the department. The class only meets as a whole for the first four weeks of the semester. During these lectures you will meet the Course Staff, learn about specific requirements, resources, and project choices for the course, and have a chance to meet other students. These are some of the most important weeks for the class since the decisions you make during this time will determine what you'll get out of this class and, in many ways, how much you'll enjoy it.

In this course, you will form teams and propose projects that solve an engineering problem in a unique way. The projects generally involve a device that you will design, build, and demonstrate. We are excited to see what projects you create with this semester! In the midst of an ever changing learning environment, we want to encourage you to think, create, design, and build exemplary projects. We want to ensure that your experience in 445 demonstrates your potential as an engineer graduating from the University of Illinois.

This course is taught hybridly for ME and ECE students, and some projects are mentored by ZJUI faculty. Here are a few items that you will need to consider as we enter into this semester.

PROJECT TITLE

Robot for Gym Exercise Guidance

PROBLEM

In modern society, daily fitness is a necessary life choice for healthy people. When it comes to fitness, the standard of movement is very important. However, hiring a coach exclusively for instruction is sometimes not a convenient and economical option. We think robots are perfectly capable of determining whether a person's movements are in place. To this end, we need to propose a scheme to design a robot that can walk behind people and use certain technologies to identify human movements when people are moving, compare with the existing action models, and give an evaluation.

SOLUTION OVERVIEW

Our solution is to design a robot that included a chassis that drove the motion on the bottom and a computer operating system and camera on the top. With ultrasonic radar and cameras, the robot can follow the target. When the "motion assessment" module starts to operate, the camera will capture video information and begin motion analysis at the same time. The analysis of human motion will be completed as soon as possible and the standard evaluation of motion will be given. At the same time, we will design some multimedia files, such as sound and video, to interact with the user.

SOLUTION COMPONENTS

Based on the introduction above, several systems need to be implemented to realize the solution.

SUBSYSTEM 1: BOTTOM MOBILE PLATFORM PROGRAMMING

We plan to take use of the EAI SMART robot platform as the base movement platform of the robot. We will do the programming based on the ROS system to realize automatic navigation, path planning, and object tracking.

SUBSYSTEM 2: SKELETAL BINDING AND MOVEMENT ANALYSIS OF THE HUMAN BODY

The most important part of this program is that we will use the Mask R-CNN to do the skeletal binding to determine the human's movement. We will try to train an efficient model to help us realize fast analysis.

SUBSYSTEM 3: MAN-MACHINE INTERACTIVE SYSTEM

As a user-oriented product, we need to design a friendly human-computer interface to realize the free conversion of functions.

SUBSYSTEM 4: MOVEMENT STANDARD ALGORITHM

We need to devise an algorithm to assess the deviation between the gymnast's movements and the standard. This algorithm is very important for the final product performance feedback.

CRITERION FOR SUCCESS

The robot can self-navigate to find people in the gym.

The robot can monitor the person doing exercise and extract human poses.

The robot can check whether the person is doing correctly in the exercise.
