Mechanics_Steering system

-

As the first part, I am going to write a bit about the steering system I am going to use for this version. Steering is a system of components, linkages, etc. which allows any vehicle to follow the desired course. I am going to use parts of a steering system from an RC car which is quite similar to a real world steering systems:

A simple steering system

 

More on steering system

The original system had some thing that could only turn the wheels completely to the left or to the right(no intermediate positions). It was very simple and did not give a good control over the car so I changed it with a servo motor( Futaba S3003 ):

Futaba S3003 servo motor

this way we can control the angle of steer freely and easily using PWM. I fixed the servo using a bracket, bunch of bolts, spacers, and plates and screwed the tie rods to the crossed horn of the motor:

I am also going to use(probably) a lead-acid battery which is very heavy, and add it a lot of other different stuff, so I also added two soft plastic rods to reinforce the front shock absorbers.

Added rods

That's it for this part.

  A chassis is the load-bearing framework of an artificial object, which structurally supports the object in its construction and function. More on chassis   Chassis    For this part I used a couple of metal plates and a few spacers to build a chassis and fix front and rear parts: Metal plates  First I fixed all parts on a one piece plate, but then I decided to make it more flexible and give the chassis a bit of freedom so that front and rear parts be able to turn around the same axis independently. I used a wheel like this: I fixed front and rear on two separate plates, removed the plastic wheel and used it to connect two plates. Connection between two plates   So this is the final chassis:    Completed chassis Underneath and so this form is possible now:  After all, obviously this way of fixing two parts is in no way vital and even may cause problems and be changed later.   Arash Ardeshiri June 30 2021  '

Software_Video streaming services

This is the last part of the first phase. With this part completed we can control the cub while being able to see through its camera (probably even cameras) connected to the cub's raspberry pi. First I was going to use VLC for streaming the camera video but aside from an annoying 3-5 seconds delay, I did not have any easy access to individual frames for further possessing, so I decided to write a simple service for it using python, flask, and Open-CV.  The webcam used on the cub First I wrote a simple web server running on cub raspberry waiting for requests from the client-side, capturing a frame and responding with the captured frame when receiving a get request. Then I also added some meta-data to the returned data, representing frame dimensions and channels to make it easier to decode the frame automatically which happens on the client-side. Soon I realized I need to be able to change both dimensions and channels of the frames from the client-side and added some meta-data regard...

Software_Joystick service

As mentioned before in this phase, before making it autonomous I am going to use a joystick to control the cub. This is what I am currently using: Logitech Extreme 3D PRO There are many ways to get the output from these devices. There are lots of libraries and we can even read the data directly from the device which is not flexible. For this purpose I am going to use SFML which is basically a lightweight 2D game engine and I have some experiences using it. The way this library is usually used is through the game loop, the loop that goes on and on through the entire period of the game, each time returning all of the events regarding mouse, keyboard, joystick, etc in the context of the game window. Since we don't need the game window and the game loop we should use the other way.  We are going to use it using the update function manually and subsequently checking for the joystick events.  To make the code more open-close I used observer/observable pattern. There is a class calle...
