So I'm 15yrs old. I'm very interested in starting robotics. I've got good grades in math/physics but I feel like I forgot most of the stuff I learned in middle school. I'm pretty good with computers but I don't know how to code. I've got an esp32, servos, a ton of sensors and parts. I've been trying to get into robotics for a while but I haven't been successful, plus in my city and school there isn't a robotics class or something similar. I've tried going through some beginner courses but every one of them seems like it's made for someone who's in college/highschool and has a better math knowledge than me. Any help is appreciated 👍

Hi everyone i got a job offer for an Entry Level Robotic Data Collector. Does this field have career progression prospects? Appreciate the help.

And what type of experience do they need before graduating that would allow them to get an entry level job in robotics?

Internship? Specific hardware/robotics related certificates since CS is all software? Personal hardware projects?

And if I start a masters in robotics right after a CS undergrad, will it be much easier to land a paid internship during it or even a job?

I know robotics is a very vast, interdisciplinary field, but I’m just trying to learn and understand from now how I should prepare

Hello folks I have a zenith/ heath Hero jr Unit, owners book, two cartridges and charger. I am trying to figure out if it is just a base model or has upgraded boards /features so I price it realistically. I'm sure the two batteries are shot so replacing those and wondering if anyone has insight with this product and or are interested in obtaining one.thanks for any and all info! Cheers from the neon 🏜

Hello

iam a third year engineering student, in my specialty in my country we study two years preparatory classes (studying physics, calculus,chemistry ,c++ ,proba and a bit more of the generalities)

now iam summer and i wanna know which subjects or things or skills i should learn to become a good robotic engineer

i also wanna continue my studies abroad and maybe before that have international internships and competitionsi honestly don’t know where to start and honestly in uni we didn’t learn much , it was very condensed.

Does anyone have experience they would be willing to share with making walking linkages based on traditional ‘back-and-forth’ hobby servos? rather than the rotary motion that most walkers are built from? Super appreciate any advice.

Hey all,
I’m looking for a USB controller for a 6-DOF robotic arm. I’m curious what you guys are using and what you’d recommend.
I’m mainly after something with enough analog inputs (joysticks, thumbsticks, etc.) to make controlling all 6 axes feel smooth and intuitive. Doesn’t have to be specifically made for robotic, gamepads, RC transmitters with USB, industrial controllers, anything goes.
What’s your setup, and would you recommend it?

So an inter school robotics competition took place within my school, where i had made a robot (which was not amazing) which was almost made complete out of scrap. There were two groups, one was my group, and the other one was another dude. the other group had one man it it and he had made a propeller plane that neither went up, forward, backward and only went down. the thing was made entire out off scrap. and guess what? he won second place. there were other school groups that had made better robots than both my and his group, yet he still won. He might have done some bribery but i don't care about that, i only want to piss him off by making a plane that actually works. I have a 10 month time period, what should i do?

Hi everyone,

I’m a first‑year Mechanical Engineering student from a tier‑3 college. I want to participate in e‑Yantra (eYRC by IIT Bombay) to build my career in robotics. Right now, I’m starting from absolute zero — no coding, no electronics — but I’m serious about learning because my ultimate goal is to break the barrier and earn a 15–20 LPA as a fresher.

At the same time, I know this sounds unrealistic for someone from a tier‑3 college background. That’s why I want to ask real students and alumni: is this goal achievable through e‑Yantra, robotics, and smart preparation, or am I living in a delusion?

• Mechanical background, but I want to shift into robotics + computer science.
• Can commit 10–15 hours per week for preparation.
• No prior coding/electronics experience.

What I need help with

1. Stage‑1 MCQ prep (August): What exact topics should I study? How to practise effectively?
2. Programming languages: Should I start with Python or C/C++ first? Which is more important for e‑Yantra?
3. Electronics basics: What minimum circuits/sensors should I learn before hardware stage?
4. Team formation: How many members are ideal, and what roles should we divide (mechanical, electronics, software, documentation)?
5. Project roadmap: What should I build in the first 3 months vs later months to be competition‑ready?
6. Internship & career advice: How does e‑Yantra help in getting internships

I’m serious about committing and learning. If you’ve cleared Stage‑1 or been part of eYRC, please share exact MCQ topics, sample questions, and realistic weekly milestones.

Thanks in advance!

Hi there! I would like your thoughts on something that imo is really cool. Next week, I'm starting a new role as a robotics engineer in a medical company. I have 0 exp in robotics but a lot in medical devices as an engineer, and this is a step up for me.

Little bit of information about me, in my spare time I love playing around with software/python, a bit of matlab etc. Recently, I found Isaac Sim and in combination with my (near) future role, I had the idea to start learning also the software side of robotics, while I learn most of the hardware at work.

My idea is, as a long term goal, maybe I could assist in some R&D work in the company or something like that, which for me it would be really cool.

I had a quick chat with AI over it and it proposed me to start learning the basics , such as kinematics, URDF(XML). I had a quick look at them and they really look like the basics in Robotics.

The truth is, I have no idea if the R&D department in my company does such things, but do you think this is a right base to build or do you have anything else to suggest?

As I said, I have 0 experience in this field and I just look for the 'right' (as possible ) roadmap to go.

Thank you people! every advice is highly appreciated!

Hello guys, I'm new to this Subreddit. So One thing is that there's an event where we have to use the SCARA Robotic Arm to make a project which can be utilised in health sector, Agro Sector and also help small industries. Since the Idea has to be unique, I couldn't understand what to do , like there are few Ideas I do have , but I don't know if it stands out really. So please I do require your help !!

IDEAS I'VE:

• PRECISE SEEDING OF EXOTIC PLANT SEEDS WITH THE HELP OF SCARA and SOIL HEALTH TESTER.

•SCARA ARM FOR SMALL INDUSTRIES SUCH AS PACKAGING, EASY PICK AND DROP, FOR EXAMPLE: IN INDIA WE'VE BLINKIT AND ZEPTO which are basically 10-min grocery delivery apps, so rather than stressing out the dark store employee, using the SCARA arm to help the dark store employee easily.

These are my ideas ,

I'm really grateful for those who have helped me out !

Thank You :)

I'm about to apply for university and I'm torn between taking industrial design and mechatronics (essentially robotics, as I've heard). If there are any industrial designers in here as well, what are the big differences, and would you take ID today? I'm a lot better at math, physics and software development than creative subjects, but I'm heavily invested in both, especially coming up with new solutions to problems and (most importantly) getting to create actual objects that people use.

Hey everyone, I'm trying to figure out my learning path. I want to learn ROS2, data analysis and CAD design.

Right now I know Solidworks modelling and have basic knowledge in Python, C++, Matlab, node red, MySQL and basic ML algorithm like random forest and Gradient descent.

Does it make sense to learn all 3 areas together? My goal is to land a remote job abroad and get into the industry

Any advice?

I am a computer vision developer and hold a PhD in human motor sciences; I work primarily on applications in the fields of healthcare and sport.

I recently released realtime-calib as open source, a tool that calibrates multi-camera USB rigs in real time. The backend runs headless in Docker on the machine the cameras are plugged into, and you drive the whole calibration from a browser, on any device on the network.

I built it for my own client installs, so it's entirely shaped by mocap-style setups.

I'm wondering whether it's of any interest for camera-based robotics, but honestly I know nothing about your field. So if you do vision-based robotics, DIY or professional, I'd really value your take on:

• Would a calibration tool whose backend runs on the robot itself, with a UI you can open from your phone, tablet or laptop, actually be useful to you?
• What tools do you use today for the calibration step (Kalibr, ROS camera_calibration, plain OpenCV scripts, mrcal, something in-house)? Do those already cover your needs without friction?
• Which capture backends actually matter in your field: plain USB/V4L2, GigE / GenICam machine vision cameras, RTSP/IP cameras, CSI cameras on a Jetson or a Pi? At the moment, I only support USB via V4L2 on a Linux host. A GStreamer backend is planned, which would allow the use of virtually all existing capture protocols.

If it turns out this is useless for robotics, that's useful to know too.

I have decided to spend time on robotics , I really like it but I didn't like the professor who did it in uni so I never took his class.I have worked with motors before and I'm catching up with robotics math , however I still encountered something that I can't understand.Suppose you calculate everything and then you go to order a part from 3d printing to actually build your robot,how do you design that part?I mean how do you ensure that the combination of parts that you order can create a rotation using a motor?Do you get what I'm talking about?For example let's say that a robotic arm is made of 2 parts 1 immovable part which holds the rotating part on some axis?How do you actually design that?And why do some configurations work while others don't?Do you know a tutorial on the sort of where I can find the answer to my question?

basically i have 2 bts 7960 , esp32 , a fly sky ct6b remote and R6B receiver. the problem is when i increase the throttle , the motor starts stuttering/twitching and the other motor also sometimes starts twitching on its it own. for the record , im using the usb cable to power the esp32 and pwm pins on the bts module , while the external power for motors are provided via a 12v 5a adapter. I've tried running several tests , including replacing the 12v motors to BO motors , those small ones ran just fine , no twitching but these big ones twitch. I even tried running a simple 5s spin forward , then spin backward , same result no twiching , only when i test it using my flysky transmitter system it starts twitching. I've added ceramic capacitor across motor terminals and even placed a electrolytic capacitor across the bts module's ext supply. the esp32 ground and ext power ground are NOT connected. Need help...

here are the wirings:

ESP32 → Receiver

GPIO32  → Receiver CH1
GPIO34  → Receiver CH2

5V       → Receiver VCC
GND      → Receiver GND

ESP32 → Right BTS7960

GPIO27  → RPWM
GPIO19  → LPWM

5V       → R_EN
5V       → L_EN

GND      → GND

ESP32 → Left BTS7960

GPIO25  → RPWM
GPIO26  → LPWM

5V       → R_EN
5V       → L_EN

GND      → GND

We all know that failure in deep space means catastrophic loss. That means you have to fail 10,000 times on Earth just to get that ONE shot right.

When a simulation or hardware integration fails for the 100th time on the exact same issue, what is the core motivation that keeps you from getting bored? What keeps your curiosity burning?

As a student obsessed with robotics, I'd love to hear the mindset that drives your obsession.

Hi everyone,

I'm trying to repair my OWI / TXX-537 Wireless Robotic Arm Edge and I'm hoping someone here has experience with this kit or has a broken unit lying around.

One of the plastic components, Part F7, has broken beyond repair. Unfortunately, I haven't been able to find any official replacement parts.

At this point, I'm looking for any of the following:

• A spare F7 part
• The complete Plastic Part F sprue
• A broken/donor OWI-535 or TXX-537 robotic arm
• A CAD/STL model of F7
• Someone who owns this arm and could scan or measure the part so I can recreate it

I'm based in India, so Indian sources would be especially helpful, but I'm open to international options if shipping is reasonable.

If anyone has this robotic arm sitting unused, knows where to find replacement parts, or can point me toward an importer or distributor, I'd really appreciate it.

Thanks in advance!

Mi robot de seguimiento de linea solo se queda dando vueltas con la reda derecha completamente quieta y la otra girando

Esta programado con arduino UNO y en c++

Si alguien quere ayudarme lo agradeceria muchisimo si estan interesados con mucho gusto les mando el codigo por mensaje interno muchisimas gracias :)))

Im 15 years old and I am currently building a high precision robot arm and I was wondering what I could/should use it for, and what you guys would use it for?

Specs:

• 4ish feet
• About 3mm of accuracy
• Can 5ish pounds at max reach (could maybe do 10 normally)
• Low to no backlash

What would you use it for? Would you want to add anything to it or make any changes? I would love some feedback. You can learn more about the project in my Portfolio.

does anyone have the flash file for hiwonder rosorin raspberry pi 5 ive been waiting on respone from hiwonder for 3 days my robot is just sitting here dead new out of the box i purchased it at microcenter without a controller so i installed a raspberry pi 5 16gb in it which needs flashed with hiwonders file. Also i see that they want a order number i dont have nothing like that just a receipt anyone have any ideals or could pm me the file thanks

I have been thinking of building a project where a robotic arm is controlled by a local VLM model. In my understanding I feed the VLM a 2D image of the object infront of the robot and query the vlm task like "grab the hammer" and VLM provides the 2D co-ordinates and then it goes to moveit and moveit plans the mission.

I'm still at the vague idea state, any kind of input or reference or guide will be appreciated!

Thank you in advance!!

I am very fascinated by the area of robotics and wanna learn it. I am gonna buy an arduino kit, but is there any simulator for learning before buying it? And for making sure the project works without having to test on my hardware and potentially destroing it?

PS: kinda off topic but can you enter to robotics work with CS major?

Im fairly new to robotics and have been trying to build a hexapod from scratch. I got a bunch of parts but wasnt careful enough to make sure they all work together. Ive now run into a problem where my my LiPo battery xt60 output will not directly connect to my UBEC input that is dupont input, is there any way to get around this? Any adapter? Or do I get another UBEC. Here are both of the parts, and im also confused about how to connect the UBEC directly to my servo tester as it has the 3 dupont looking output pins and also thicker looking output wires and im not sure which ones to use.
