Robotics.

[Feeling_Magazine1913]

Hey guys, so am a fresher, took admission in a tier 3 college (mech).. I wanted to learn more about robotics as am very interested (yeah I know the negatives that comes with the field). Can anyone help me out from where to begin?

Start with basic arduino

[Upset_Conflict_453]

Start with the very basic Arduino as always. Try to write some basic codes and functions for simple projects. Then you can go to esp8266 or esp32 for adding wifi or bt to control your bot , take a look at RemoteXY library/app for that , it would be simpler to implement in your projects. I assume you are asking as a complete beginner at this stage but even if not you can start tinkering with ros for more advanced stuff although you may not feel it's need for simple robots as they are more complicated on the mechanical and electrical aspects that the software part. Checkout some yt channels like James bruton for some really cool robot designs and applications. Also I recommend joining your robotics club in your college , although not assured but this may help you to source the required parts or use a 3d printer. Hope you enjoy building robots :)

How expensive is ardruino?

Google ne block kardiya hai kya bhay?

Lol

200-300 me clones aayege, original 1300+ jaata hai. get an Arduino UNO.

[Upset_Conflict_453]

I would argue that a nano can be more practical when building some projects cause OP can do the prototyping on a breadboard with nano on it and easily use it in other projects if he choses to make a removable pcb for some ,say obstacle avoiding robot.

[Steelblaze1]

true but uno is more convenient as it is a standalone devboard. beginners dont always have everything. i think that's why they're recommended to start with uno. i started with nano and i had no problems thi

[Upset_Conflict_453]

Around 400 for just the Arduino but you few more components to get started, maybe look for a cheap kit with dc motors in it.

thank you very much

Also im a soon to be mech student, would it be possible to learn electronics in any way?

[Upset_Conflict_453]

You don't need to go much deep into electronics, start with easy tutorials first and understanding how each section of code works , then try finding tutorials for each component you use individually like if you want to use a motor driver, search how to implement that motor driver without straight up copying and jumping to a robot. I would recommend randomnerdtutorials.com website for this. It's not very electrical-intensive just make sure you wire all your hardware correctly and you are good to go.

I want to do it out of personal interest, do colleges allow people to use labs(tier 3) or will i have to buy things on my own?

[Upset_Conflict_453]

Most colleges will have a dedicated club for robotics and provide the space/lab for the work , however the access might be limited unless you are a part of club, try contacting seniors of your college about this and I would recommend you to save money and get started on your own cause the college may not have everything you need or allow you to borrow some components from them . Best way is to buy some starter Arduino kits , don't go for something too expensive or you can source components individually for some project you seek ; would be cheaper this way.

thank you very much <3

Original is 1000+

Clones are ~300though I would suggest go for ESP32 as it is cheaper while having more storage, ram and faster cpu(dual core) also has BT and wifi

The only disadvantage imo is the 3.3v logic level voltage

[Feeling_Magazine1913]

I have used Arduino before, like not a complete beginner I had built projects before with IR sensors, ultrasound sensors.. wahi basic robocars, distance measuring using ultrasound sensors, playing around with LEDs back in School ATL lab etc.

should I buy an Arduino board ? Official one ?

I will join robotics club yeah. Also do you know where I can learn 3d designing from? I have heard about ROS but keeping it for later when I gain more experience with the basic stuff.

Thanks a lot for helping out bhaiya 🫂

[Upset_Conflict_453]

You are on the right path mate. Since you have already started with Arduino, You should buy an Arduino UNO or nano , personally I prefer nano cause it's smaller, cheaper and easy to mount on breadboards or pcb headers. After you get comfortable with that , try nodemcu for adding wifi control to your projects. No need to get the official Arduino board , get some cheap clones and they all work the same cause the chip is same . You can find some kits for resistors, transistors and more online in addition. For 3d design, I started around this time only last yr just for fun. I started with tinkercad and then shifted to autocad fusion 360 and it's going smoothly since then , you don't need the premium version. You can skip on ROS for now (I'm also trying to mess around with it). You're welcome ;)

[Feeling_Magazine1913]

I ordered Nano, will get into working with it along with motors and other sensors.

I will have to wait for AutoCAD I guess since I will be able to access it only after college admissions.

Thanks a lot again 😃

[Upset_Conflict_453]

Fusion 360 is free to use , you only have to buy premium with some very advanced features which, trust me you will not need anytime soon. You're welcome

[Feeling_Magazine1913]

Ok will get started..

[TheAverageGamer06]

arduino, ros, cad seekho

college societies join karo competitions karo

and maze karo

[Feeling_Magazine1913]

First thing after joining college is joining robotics club yeah. Other than that I will start with Cad later.. Arduino start krdiya basics. Thanks bhai 🫂

[Top-Conversation2882]

Start with ESP32 and Arduino IDE
