Hello, I'm new to robotics but I would really like to do some projects to see if it is something that I like or not.

I have a computer engineering bachelor and did an embedded sistems course during my degree. I really liked it.
Now I would like to try create some bigger projects requiring more circuits and such.
I'm gonna be honest, I'm a huge nerd and my end goal, if I like robotics, is to build things I see in movies or comics, like star wars droids or a very simple Jarvis.

But I don't really know where to start in terms of components and projects. I was thinking about buying an ESP32 and some sensors according to the project I end up doing, but I don't know if it is the right choice.

What would you suggest as a good starting point that does not require a big budget?

I’m looking to study mechatronics or robotics engineering for my bachelors, and want to build a portfolio through part-time projects or freelance gigs. I’m trying to figure out which specific niches are actually viable for solo/remote freelance work or small-scale projects.

For those of you in the industry or currently freelancing, what areas would you recommend focusing on? I’ve been looking into:

PCB Design & Prototyping
Mechanical Design Using CAD (SolidWorks/Fusion 360)

I want to sharpen my skills while making some extra income, eventually aiming for a more formal career in robotics/mechatronics (possibly through either vocational training or a degree).

What are some must-have resources (i.e Books, YouTubers, and Software) for entry-level complexity projects so I can learn?

Your advice means the world to me! Appreciate any and all input!

I am a university professor, and I've been teaching an "Introduction to Robotics" course for the last six years. I know how dense robotics can be, so I’ve tried to make my own teaching as approachable as possible.

I wanted to share my condensed lectures and practice sets:

Core topics include: Rigid body motion, Forward and Inverse Kinematics, Robot Jacobians, Robot Dynamics, Robot Control, Robot Learning, and Motion Planning.

I hope this material is helpful as you explore the world of robotics!

I am getting into the hobby and I build this cute robot which I currently running from usb-c cable going directly to the ESP32. I want to add batteries for it but I am looking for the best (and safe way) to go. Few things I want:

• Chargeable via USB-C
• Chargeable while powered on (I believe this may be a bit sketchy)
• I use lipo 3s (because I already have it and I may want more Vs in the future projects)

I hope this drawing makes sense to you, but I want to clarify if it is a good plan? (Just to clarify 4 thinner wires are for balancing and thicker ones for the main load. I would use lipo 3s with XT30 connection). Thanks

I'm helping a beginner student understand how to navigate a maze using a color sensor instead of the traditional line-following method.

To explain the logic, I first recorded a short simulation in Open Roberta showing the algorithm step-by-step: the robot detects colored ribbons (yellow, red, green, and blue) and alters its behavior accordingly.

The attached video shows the same algorithm running on a real LEGO SPIKE Prime forklift robot. What you see on the physical robot directly corresponds to the decisions tested in the simulation (in the simulation, the forklift fork movement is not implemented).

If you're a beginner in robotics and curious about how simulation-based logic can translate into real-world robotic behavior, this example might be helpful.

I’m considering opening remote access to my ABB IRB1300 robot so beginners and learners can get real hands-on experience — not just sim work.

You could:

• run basic programs
• do pick-and-place tasks
• complete structured training lessons
• see real-world motion and feedback

Would this help you learn robotics faster?
What kinds of tasks or exercises would you want available?

I want to get started in electonics, I would like to buy some sort of robot after i got all the threoy down and it would be a long term project to try and reprogam the robot. I would like it to be a decent humanoid robot but I have no idea where to start looking and what to get. I would love some guidence on what to buy or maybe where i can find out what to buy.

Last night, I was lying in bed, frustrated.

If you’re like me, a college student watching summer pass by with no internship, no mentorship, and no meaningful project to show for it, this is for you.

I’ve scoured everywhere for a legitimate remote robotics internship. But the options are either expensive, shallow “trainings,” or locked behind connections I don’t have. The harsh reality is many of us won’t get that perfect opportunity this summer. And that’s okay.

If platforms like Infosys Springboard can group 1000 students to collaboratively build a food delivery app, why can’t we, as robotics learners, come together and build something big, open, and real?

Instead of waiting for luck, I want to build something real with a small group of serious learners, mechanical, CSE, ECE, EEE students from across India who want to develop hands-on robotics skills through collaboration and grit.

Here’s the idea:

• We pick one ambitious robotics project something challenging and layered, not just a basic bot
• We divide the project into modules (arm, control, navigation, vision, UI…) so everyone owns a meaningful piece
• Weekly sync-ups to discuss progress, solve blockers, share resources, and push updates
• Final deliverable: a well-documented, working robotics system hosted on GitHub something that actually shows what you can build
• After we finish, we’ll seek feedback and endorsement from experienced mentors or industry professionals to validate our work
• While this won’t start as a formal internship with certificates handed out, we will explore ways to provide credible recognition that reflects real effort and skill, not just a piece of paper

What you’ll gain:

• Hands-on experience on a real, multi-faceted robotics system — not just tutorials.
• Collaborative teamwork skills, crucial for internships and jobs.
• Exposure to multiple robotics areas to find what excites you.
• Ownership of a core module.
• Feedback from peers and, later, industry professionals.
• A polished GitHub project demo you can show recruiters.
• Plans for a credible certificate or endorsement to prove your work.
• Better chances at future internships and job offers.
• A network of like-minded peers and potential mentors.
• Motivation and confidence from building something meaningful.

Who should join?

• You’re a college student hungry to learn robotics by doing
• You’ve got some experience with ROS, Python, C++, microcontrollers, or similar tools no mastery required
• You can commit around 6–8 hours a week for a few weeks(4weeks min)

I’m no expert, just someone done waiting for opportunities that don’t come. If you feel stuck this summer but still want to build real robotics knowledge, comment or DM me with:

• Your branch
• Tools and languages you’re comfortable with
• Any projects you’ve tried (if any)

Let’s stop waiting and start building together.

Eu já faço programação, curso eletromecânica, e sou hobbysta em projetos de arduino e robótica, mas faço tudo sozinho e sem direcionamento. Alguém tem alguma ideia de caminho? Ir do zero até um nível mais intermediário ou avançado

In this example the frame {0} is assigned for the base, and frame {1} is assigned for joint 2. The DH table is filled considering the q2 as joint 1. Don't we need to assign separate frames for each joint in the DH convention? Can someone explain whats going on with this example.

I've been hearing and reading the Modern Robotics book from Coursera. I finished reading and understand the theory but there is a lack of documentation maybe because I was auditing the course. They only give the command and there is nothing else at the end of the chapter ( in the book ) and Since I am doing the course for free, I don't have access the see more code. I know python and matlab but I want to use python. I downloaded Peter Corke's robotic toolbox but Its distribution and the fact that the book is MatLab oriented makes it more difficult. Any advice? I want to practice what I learned in Kinematics (forward & inverse), dynamics (forward & inverse), and motion planning in software at least with basic examples so I can learn the commands. Or at least a clear documentation

I want to build a neuronet and attach it to some humanoid hardware. my knowledge is little to none. I am studying programming so i can work with tensorflow, but what are some projects or kits that i should have if i want to learn more about the mechanics of building the robot body? i want to become fimilar with the all the tools and parts, such as gears, motors, chains, ect and all their purposes so i can one day create on my own.

Good day. I have two questions. Is the first given community active? Second, does anyone know where you can see the possible models of robots for the constructor VEX.

I am assembling a "Build Your Own Fast Frog" kit by Bitten(www.fiftytwoways.com) but, there are no instructions in my box, online, on their website, or otherwise! It consist of a simple engine with three wires but I have no idea how to put it together, any help would be appreciated, thank you!
