2-click-newJPG

Click OK on the window that pops up once you’ve selected your desired working directory.

Click New.

Select Sketch.

3-select-sketchJPG

Click OK.

Go to File -> Options -> Sketcher.

Under “Accuracy and Sensitivity” change the Number of decimal places for dimensions to 3 (I like to use 3 decimal places).

Click OK.

Click No at the prompt.

4-click-no-at-the-promptJPG

Click the small arrow next to Rectangle on the Sketch tab on the top of your screen.

5-small-arrowJPG

Select Center Rectangle.

Click a point anywhere.

Drag to create a rectangle.

Click another point to create the rectangle.

Click the Select button to stop creating rectangles.

6-select-buttonJPG

Double-click on one of the dimensions in order to alter it. In this case, I will make both the length and the width equal to 10.000.

7-my-rectangleJPG
8-length-and-width-equal-to-10JPG

The little green squares indicate the constraints. For example, the green square with the black line indicates that the corresponding side of the square is exactly horizontal. Likewise, the sides are vertical. 

To shift the view on the screen, you hold down the Shift key on your keyboard while holding down the middle mouse button (or pressing the scroll wheel on your mouse). It is a bit awkward, but it is what it is.

Similarly, to rotate the object in your view, hold down the Ctrl key on your keyboard while pressing the middle mouse button (or pressing the scroll wheel on your mouse).

You can move the position of the dimension labels (e.g. the 10.000 markets) but click on them and dragging them to where you want them to be.

To save your rectangle, go to File -> Save and then click OK.

How to Install Pip on Ubuntu 20.04

In this project, we will install pip. Pip makes it easy to manage software packages written in Python.

You Will Need

Directions

Log in to your Ubuntu Linux machine.

Click on the nine white dots in the lower left of the desktop.

1-six-dots

Type “terminal” in the search blank, and then click on the Terminal icon.

2-terminal-search-blank

Before we install anything, let’s make sure we have the latest list of available packages. Let’s also upgrade the system if necessary.

Type the following command in the terminal window:

sudo apt update

You’ll need to type your password and then press Enter.

Now, let’s upgrade our system.

sudo apt -y upgrade

The -y flag means that we agree to upgrade our system to the latest and greatest software packages.

Now, we need to install pip. Type the following command and press Enter:

sudo apt install -y python3-pip

Pip should take a minute or two to install.

If at any time you want to install a Python package, you use the following command:

pip3 install package_name

You’ll need to replace package_name above with the name of the library or package you want to have installed.

For example, let’s install some mathematical packages. We will install numpy (scientific computing library), scipy (scientific computing library), matplotlib (graph plotting library), and sympy (computer algebra library).

Here is the command you need to type into the Terminal:

pip3 install numpy scipy matplotlib sympy
4-install-math-packagesJPG

That’s it!

How to Install Ubuntu 20.04 and VirtualBox on Your Computer

In this tutorial, we will install Ubuntu and Virtual Box on our personal computer. My machine is running Windows 10. Let’s walk through this whole process, step-by-step, so you understand how to do it no matter what operating system you have.

Ubuntu is a popular distribution (i.e. flavor) of the Linux operating system and is fully supported by ROS, the most popular framework for writing robotics software.

The process for installing Ubuntu has a lot of steps, so be patient and don’t give up if something isn’t working. Let’s get started!

You Will Need

Directions

Download the Ubuntu Image

Check Ubuntu Releases to find the latest version of Ubuntu that has long term support (LTS). As of the date of this writing, the latest version is Ubuntu 20.04 LTS (Focal Fossa), so click on that one. 

1-ubuntu-releasesJPG

Download the 64-bit PC (AMD64) desktop image (.iso file). It is a large file (about 2.5GB) and will take quite a while to download. Just go do something else and come back to it when it is finished.

Before you install the Ubuntu you just downloaded, you need to install Virtual Box. Virtual Box extends the capabilities of your host computer (i.e. your laptop or desktop PC) by enabling you to install and run an operating system in a new environment on top of your current operating system (Windows 10 in my case). The environment the new operating system will run in is known as a virtual machine (or guest).

Install VirtualBox

Go to the VirtualBox downloads page and select the version that is compatible with your computer. Install it. Once you’re done, your screen should look like this:

2-install-virtual-boxJPG

Detailed installation instructions for all operating systems (Windows, Mac OS, Linux, and Solaris) can be found in the instruction manual.

You can now delete the original executable file for VirtualBox (the one with the .exe extension). You don’t need it anymore.

Create a Virtual Machine

Now that VirtualBox is installed on your computer, we need to create a new virtual machine.

Open Virtual Box and click the New button in the toolbar.

10-start-virtual-boxJPG

Type in a descriptive name for your operating system. You can stick with the default machine folder. The machine folder is where your virtual machines will be stored. I prefer to install it on the D drive where I have more space.

3-name-and-operating-systemJPG

Also, select the operating system that you want to later install (Linux and Ubuntu_64 in the Type and Version fields).

Click Next to proceed.

The default memory size for me is 1024 MB. That is not sufficient for our purposes, so let’s raise it to 6470 MB, and then click Next to proceed.

4-raise-to-6470JPG

Make sure “Create a virtual hard disk now” is selected, and click Create.

5-create-virtual-machineJPG

Select “VirtualBox Disk Image (VDI)”, and click Next.

6-select-virtual-box-disk-imageJPG

Choose a Fixed size virtual hard disk so that you have better performance, and click Next.

7-fixed-sizeJPG

Go with something like 50 GB for the hard disk space. Then click Create.

8-go-with-50gbJPG

It will take several minutes to create the virtual hard disk, so be patient.

9-creating-hard-driveJPG

Install Ubuntu

Double-click on the left panel where you see the name of the virtual machine you just created.

10-double-click-left-panelJPG

A startup window will appear.

Click the Folder icon next to Empty. A popup box will appear that is titled “Optical Disk Selector.”

Click Add.

11-optical-disk-selectorJPG

Find the Ubuntu image you downloaded earlier in this tutorial. It is a .iso file. Select it.

Click Choose.

Click Start to proceed with that Ubuntu image.

Ubuntu should start launching.

12-ubuntu-launchingJPG

Click on “Install Ubuntu” to install Ubuntu. You should see a window that looks something like this.

13-install-ubuntuJPG

Click “Continue” to save the keyboard layout. The default English one is fine.

Select “Normal installation” and “Download updates while installing Ubuntu.” Then click Continue.

14-updates-and-other-softwareJPG

Select “Erase disk and install Ubuntu”. Then click “Install Now”.

15-install-nowJPG

Click Continue when it asks “Write the changes to the disks?”.

You will get to a point where you will need to set your time zone. It will be a big map of the world that should automatically detect your location. Click Continue.

Type in a computer name and pick a username and password. I select the “Log in automatically” option.

When installation is complete, click “Restart Now.”

16-restart-nowJPG

A message will say “Please remove the installation medium, then press ENTER:”. Just ignore it.

Go to File -> Close in the upper left part of the window.

Select “Power off the machine.” Click OK.

In the “Oracle VM Virtual Box Manager” window, highlight your virtual machine and click the green arrow up top that says “Start”.

You should now see your Ubuntu Linux desktop.

18-homepageJPG

Click the small white arrow in the upper-right portion of the screen. “Power Off” the machine.

19-power-off-machineJPG

Alternatively, you can open up a terminal window and type the following command:

sudo shutdown -h now

Highlight your virtual machine and go to Settings → Display and change your Video Memory to 128 MB. This will give you ample video memory. Click OK.

20-ample-video-memoryJPG

Also go to Settings → System → Processor, and adjust the number of CPUs to 4. Then Click OK.

21-4-cpusJPG

Congrats! You’re done!
