ROS Noetic Installation

Today we are going to see the installation of Robotic Operating System 1 (ROS)

Step 1: What We need:

This will mainly work on Ubuntu 20.04 OS
Support till 2025 May.
Name of the ROS: Noetic

For the complete installation step by step, you can watch the video given below

Step 2: Commands

Here are the commands to be used one after the other.

$ sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

$ sudo apt install curl # if you haven't already installed curl

$ curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

The above commands add the ROS to the aptitude manager and we can now install ROS1 with simple commands

$ sudo apt update

$ sudo apt install build-essential autoconf automake libxmu-dev

$ sudo apt install ros-noetic-desktop-full

The above command need 370MB of softwares to be downloaded.

So the complete package of ROS installed.

We need some more packages to be installed that can create our own workspaces and manage our own workspaces, here are the following packages.

$ sudo apt install python3-rosdep python3-rosinstall python3-rosinstall-generator python3-wstool

$ sudo rosdep init

$ rosdep update

Step 3: Set the path information

Now set the path for a bash file.

Open .bashrc file from the home folder and set the folllwing line

Open the above file using the command

$ cd

$ gedit .bashrc

Go to the end of the file and paste the following line

source /opt/ros/noetic/setup.bash

This is how it looks

ROS path setting

and logout and login back... or restart the system.

Thats it...

We have installed ROS1 Noetic successfully in Ubuntu 20.04

To check whether it's working or not... run the following commands.

$ rosrun

$ roslaunch

$ rosmsgs

$ rqt_graph

$ rostopic

If these commands are recognised, then ROS is installed successfully.

Installation of NS2 (ns-2.35) in Ubuntu 20.04 LTS Step 1: Install the basic libraries like $] sudo apt install build-essential autoconf automake libxmu-dev Step 2: install gcc-4.8 and g++-4.8 open the file using sudo mode $] sudo nano /etc/apt/sources.list Include the following line deb http://in.archive.ubuntu.com/ubuntu bionic main universe $] sudo apt update $] sudo apt install gcc-4.8 g++-4.8 Step 3: Unzip the ns2 packages to home folder $] tar zxvf ns-allinone-2.35.tar.gz $] cd ns-allinone-2.35/ns-2.35 Modify the following make files. ~ns-2.35/Makefile.in Change @CC@ to gcc-4.8 change @CXX@ to g++-4.8 ~nam-1.15/Makefile.in ~xgraph-12.2/Makefile.in ~otcl-1.14/Makefile.in Change in all places @CC@ to gcc-4.8 @CPP@ or @CXX@ to g++-4.8 open the file: ~ns-2.35/linkstate/ls.h Change at the Line no 137 void eraseAll() { erase(baseMap::begin(), baseMap::end()); } to This void eraseAll() { this->erase(baseMap::begin(), baseMap::end()); } All changes made Step 4: Open a new termi

Square and Sinusoidal Waveform in 8051 Microcontroller

Waveforms in 8051 Microcontroller Square Wave To create a square wave generation using Delay. let us say we want to construct a 1khz square waveform the processor instruction cycle of 8051 is 1.085microseconds so for 1khz (1milli seconds =1/1khz), is 1ms/1.085microseconds = 921.6 (this value is set to the for loop) #include <reg51.h> void delay() { int i=0; for(i=0;i<922;i++) } void main() { P0=0xff; delay(); P0=0x00; delay(); } Sine Wave generation Since sine wave is plotted in a digital device the number of samples determines the smoothness, hence in this case, more the samples, smoother is the waveform. so a lookup table is been created to get the samples. in the following examples, there are totally 36 samples are taken, starting from 0 degrees to 360 degrees with a step of 10 degrees Degrees A = 5 (1+Sin theta) Where 5 is the full scale voltage DAC = 25.6 * A 0 5 128 30 7.5 192 60 9.3 239 90 10 256 etc…like this we need to calculate for 13 samples with a ste
