For the absolute begineers in 2025 who wanna really get into robotics Here's the path

Touch sensor based led trigger! With arduinoUNO

ROS2 core python code libraries Important to learn!

Not much just basic! ROS2 turtle sim

Hello ROS2 cooked!

Boring shit is always powerfull These commands look boring but can 1. Control nodes, topics,services, and parameters 2. Launch complex robot systems 3. Debug communication issues 4. Inspect what ur robot is doing 5. Record and analyse data 6. Test ur code

Trying to cook something!

For all non techies Motor has only 2 parts Stator: is static, never rotates Rotor: rotates, influenced by stator Stator is like master and rotor is slave.

Motors heat up for simple reasons • more current in copper winding so more heat from internal resistance of it. • if no ventilation in motor, no space for heat dissipation, heat compiles. • supplying more voltage than its max capacity, ofc it will heat up.

What actually matters in robots is not how u control motoring actuators But how u control the feedback sent to motor Motor will run itself, its the feedback which keep through the ups and downs of the robot.

Now thats what we are going towards huh?

Wherever copper is being used in electrical context Mica based insulation will be used bcz • moisture resistant • high temp resistant • very high dielectric strength • excellent thermal conductivity • mechanucally strong in sheet form

There are certain properties of chemical elements Individually or combined, that if used strategically can benefit a lot Like constantan + bismuth when used together in concept of "petlier effect" It acts as a heat absorber, or cooler, used for cpu/gpu cooling.

heat decreases metal's, but increases semiconductor's conductivity. For high temperature robotic applications, wires should be redesigned using semiconductor's.

Core mechanical inventory of every robot 🧵

Load on a robot is similar to u lifting ur girl Her weight is static load, u need to bear that at least. If she is holding a purse too, thats dynamic/changing weight, bearing it makes u a performer. If she moves a bit ? Thats unexpected stress, Bearing it makes u the one!

@cabeljc Robots need to first master "how to walk" dynamics properly, instead of getting more exposed to new data for running in different environments.

Everyone FEARS learning C++ But for robotics, u dont need mastery Just learn enough to: • write simple functions • understand arduino code • work with digital/analog I/O • use setup() and loop() structure • use libraries (Servo .h, Wire .h, etc.)

No hardware? No problem! Start with learning python code Its primarily used in: • ROS2 • Robotics Automation • Microcontroller scripting

Billionaires say focus on fundamentals so Here are the one's needed for Robotics • Electronics • Programming • Microcontrollers Practicing them enough to be a grandmaster!
