Reading

• Read the Rules Manual for RoboMaster AI challenge 2020

Image Processing

• What is an image?
• What is the brightness, contrast, saturation, and hue of an image?
• What is the difference between image processing and computer vision?
• Learn about various color-spaces and bit-wise operations in OpenCV and try to implement skin detection.
• Learn about contours in OpenCV and use the previously implemented skin detection with contours.
• Read and practice Chapter 1 (except PCA) of the book Programming Computer Vision with Python by Jan Erik Solem (can be found in ERA-IITK/res)
• Write a code to detect the best Armour Plate in the given image. Draw a rectangular box around the armor. (Image can be found in ERA-IITK/res)

Introduction to Linux Ecosystem- Part 2

• Getting into Linux Eco-System
  • Kernel vs. Operating System
  • What is a Daemon?
  • Difference Between Bash and sh ?
  • What is Gnome?
  • What is Shell?
  • Complete the chapters 1-5 of the book "Linux Shell Scripting Tutorial - written by Vivek Gite" (Found at ERAIITK/res)
  • Complete Challenges 1-10 (up to Functions and Fractals) on Hackerrank
    (https://www.hackerrank.com/domains/shell)

Getting into ROS Eco-System

• Installing and Using ROS

  • Installation - one line, Desktop- full, kinetic.
  • Read through Section 1.1 of Mahtani - found at ERAIITK/res

• ROS System Levels

  • Understand the Filesystem level and The Computation Graph level, and draw flow diagram, illustrating your understanding of each of these

• Introduction to Nodes and Topics

  • Use Turtle Sim simulator, and use the built-in teleop, Use the RQT graph to see the active nodes and topics.
  • Write a node that moves the turtle forward when the input is 'f' and backward when input is 'b'
  • Write a node that takes an input 'r' from the user and makes the turtle move in c circle of radius 'r'

Getting comfortable with the ROS Eco-System - CMake

• What is CMake? Why should we be using it
• Go through 'An Introduction to Modern CMake' from cliutils
  • Installing CMake
  • Running CMake
  • Complete chapter 2- An Introduction to the basics. https://drive.google.com/file/d/1Zzpkhemh-Hy6f4JnBFJeUH3KxYQ2ZabH/view
• Complete tutorial 1 made by the Cmake Foundation
• Complete Using Dependencies Guide
• Those who did not complete ROS tasks by making a package need to do it in this way.

Having fun with ROS.

• You have to work in pairs to write a subscriber publisher pair that can communicate over the network to your partner's computer.
  • Ping the network, Perform simple addition.
  • You must use a ROS based approach.
  • Submit these task as a separate compiled workspace
  • Generate the RQT graph and submit that as an image file
• Now modify your talker subscriber network such that the talker on your computer is able to control the turtlesim turtle in your partner's computer.
  • The movements are forward and backward, turn left 90* turn right 90*. The forward-backward motion must be quantized for each keypress irrespective of the duration of the keypress.
• Now modify your above program to include gesture recognition. Control the turtlesim turtle on your partner's computer using hand gestures in front of your webcam
  • The same movement constraints apply as above.
  • You must get feedback of the current position of the turtle, back on your screen.
  • Use OpenCV for image processing
• The above tasks need to be done in the C programming language and compiled as a package
