Soldering Assignment

Description

The soldering assignment is a basic soldering exercise that ensures all ECE 445/ME 470 students understand how to solder surface-mount and through-hole devices. Students will be provided with the necessary PCB, components, solder, flux, etc. The details of the soldering assignment can be found in the assignment sheet.

Your end product should look similar to the following. You will create a small device that blinks an LED at varying frequencies when the button is pressed, based on a potentiometer reading.

Below is a series of soldering tutorials. The critical ingredient that you need to make your life easier while surface mount soldering (and through-hole too) is flux. There is liquid, water-soluble flux available in the lab. If you can't find it or don't know what it looks like, ask a lab staff member or TA for help.

Requirements and Grading

The soldering assignment is worth 10 points and is graded via inspection by a TA or Lab Staff member. Students are allowed to make as many attempts as necessary to complete the assignment.

Submission and Deadlines

The soldered PCB must be presented to a course staff member before the deadline listed on the Course Calendar.

Video Tutorials

Below are a few public video tutorials on Soldering. There is also a text description of how to solder on the soldering assignment doc linked above.

## Project Title

Remote Robot Car Control System with RGBD Camera for 3D Reconstruction

## Problem

We aim to build a user-friendly control system for assisting users to remotely control a robot car equipped with an RGBD camera in complex indoor environments. The car should be able to build the environment based on the point cloud scanned by the camera, and the remote computer will reconstruct the point cloud to gain the map of the environment.

## Solution Overview

Our solution consists of a Robot Car Subsystem, Camera Subsystem, Remote Control Subsystem, and Human-Robot Interaction Interface. The Robot Car Subsystem includes a robot car and a rotating base for the RGBD camera. The Camera Subsystem captures RGBD images of the surrounding environment and performs real-time 3D reconstruction. The Remote Control Subsystem allows users to control the robot car remotely via a joystick. The Human-Robot Interaction Interface provides a third-person perspective view of the reconstructed environment and allows users to interact with the robot car in real-time.

## Solution Components

- Robot Car Subsystem: Includes a robot car and a rotating base for the RGBD camera.

- Camera Subsystem: Captures RGBD images of the surrounding environment and performs real-time 3D reconstruction using image signal processing software.

- Remote Control Subsystem: Allows users to control the robot car remotely via a joystick.

- Human-Robot Interaction Interface: Provides a third-person perspective view of the reconstructed environment and allows users to interact with the robot car in real-time.

## Criterion for Success

- The remote robot car control system can navigate and avoid obstacles in complex indoor environments.

- The Camera Subsystem can perform real-time 3D reconstruction with high accuracy and reliability.

- The Remote Control Subsystem provides a smooth and responsive control experience for the user.

- The Human-Robot Interaction Interface provides an intuitive and user-friendly way for users to interact with the robot car and view the reconstructed environment.

## Distribution of Work

- Han Yang (EE): Camera Subsystem design and implementation

- Hao Chen (ECE): Remote Control Subsystem design and implementation

- Junyan Li (ECE): Human-Robot Interaction Interface design and implementation

- Yuhao GE (ECE): Robot Car Subsystem design and implementation

## Justification of Complexity

We believe that our team has the necessary skills and knowledge to handle the mechanical and electrical complexity of our project.

Specifically, Han Yang has experience in image signal processing and Hao Chen has experience in remote control systems. Junyan Li has experience in human-robot interaction design, and Yuhao Ge has experience in robotics and mechanical design. Additionally, we plan to use readily available off-the-shelf components and design our system in a modular and scalable way to minimize the complexity and facilitate the development process.
