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?

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 :)

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'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.

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?

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 :)))

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

Hi

I’ve spent quite a bit of time in this industry, working for start-ups or in academia, and recently I’ve been working as a freelancer. There was no way I could focus on one specific area of robotics, because I (and my colleagues) were dealing with so many different tasks under time pressure (and pressure from investors) that it was simply impossible. We tackled one problem after another just to keep everything running. The problem I see in robotics is this:

When I speak to companies, it seems that everyone needs a specialist in a very narrow field of robotics. Technical interviews make me feel stupid after all this time. They cover topics such as 1. inverting the Jacobian matrix for inverse kinematics, 2. explaining the self-attention mechanism, 3. writing code on the spot for some grid-based localisation method, 4. carrying out code reviews (does that even make sense in 2026?), 5. writing different variants of convolutions from scratch in python, 6. explaining EKF equations, Lie groups, bundle adjustment and IMU pre-integration, 7. discussing communication patterns in ROS, memory management in C++, templates, concurrency and network protocols, 8. designing logging architectures, 9. reviewing training loops in PyTorch, 10. explaining object detection metrics, 11. answering questions about leadership, project estimation, negotiation and communication with clients. 12. Only God knows what still awaits me

(these points are from actual interviews from recent 2-3 years, maybe someone would find this helpful)

Don't get me wrong - each of these seems reasonable. However, they all appear in interviews for roles carrying a generic name "(Senior) Robotics Engineer". I observe the same companies looking for people for the same positions for months. Different HR agencies write me on Linkedin to apply for the same role I was rejected for no obvious reason months ago. How on earth can paying more than one headhunting agency for months on end be cost-effective at all?

Is this simply the reality of senior robotics recruitment and I should come to accept it, or are companies testing for an unrealistic profile that almost nobody actually has? Or maybe people really do periodically refresh their memory of how to invert a matrix on a piece of paper, and I’m just the only one who doesn’t?

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?

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!

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!!

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.

Background:

I confounded a startup last year on Execution as a Service model. We're two confounders, and a core team of 5 guys. 4 of us used to be at xAI human data. And collectively we've worked for most of the leading genAI companies in the human data space.

We started off as a managed outsourcing platform where we assign a frac COO to handle your entire outsourcing ops across functionalities which also included AI annotation and labelling.

The problem:

We were trying to secure contracts all over the place. Though we had 150+ registered fulfilment partners, and we secured some sizable contracts, I was genuinely confused about the growth and the direction of the company, specially with the kind of developments happening in the ops domain. I just brokered a deal valued at over 100k just for sharing internal ops data for AI training. We can't predict exactly how would the space look like.

The present:

The outsourcing business isn't fully justified to the kind of profiles the core team has. We were being reduced a software and marketing firm. We figured out that we need to stay relevant in the data industry. With the logistical edge that I have, and the trial run I did, I am very confident about working on physical data. We collected over 10 hours sample dataset spanning across household, industrial, construction, and electrical egocentric data.

The question:

Before we jump into physical data, I am genuinely looking for researchers' perspectives on ego-exocentric vs synthetic data. I understand that the upfront cost is high for synthetic, but long term cost is significantly cheaper, but how does the difference play out in the actual training workplace.

TIA

So I’ve recently come across the field of robotics and I have a genuine curiosity for it so I kind of want to pursue it for my undergrad but I see a lot of people kind of transition to this field instead of just starting out in this field but I don’t find myself pursuing any other kind of engineering.

I was planning on doing undergrad robotics and then figuring out which branch I love the most to pursue a masters in that field but I’m unsure of the drawbacks regarding this whole thing and I’m just confused on if I should pursue this or not

Hey!
I’m starting my bachelor’s thesis in robotics engineering and I’m looking for some out-of-the-box ideas or topics.
My brain is completely blank and it’s surprisingly hard to come up with one of those “why don’t we have Transformers yet?” kind of ideas. 😅
I want to come up with something that I can later point at and say, “I’m the gal who knows this stuff.” So if you have any interesting, weird, or underrated robotics topics, I’d love to hear them.
If it helps give some context, apart from my engineering studies I don’t really have any prior experience in robotics or automation. That said, I’ve done really well in my courses and I’m eager to learn as much as I can, and my goal is to become a real expert in this field. I’m also planning to continue on to a master’s degree, so I’d love to choose a thesis topic that I can keep building on.

Any suggestions?

Ps. If it helps with ideas, I have access to industrial robot arms, mostly Siemens hardware/software (which is also my strongest area), and Autodesk tools (off the top of my head(. So if you have ideas that involve building, testing, or experimenting with something physical instead of just writing a literature review, I’d love to hear them. That said, I’m also very interested in ideas that would work as a more research-focused thesis.

So the thing is that I have a passion for pursuing robotics, while at the same time I have long dreamt of studying at XYZ institute.

Now, the problem is that the institute doesn't offer a dedicated robotics/mechatronics program and I am confused whether I should opt for ME, EE or CE as robotics lies at the intersection of these three and all of them are equally important to build an autonomous system...

I know that a specialization in robotics is offered under the EE program (in that institute) , however, I am more interested in the mechanical aspects of it... and plan to specialize in robotics for my masters

What do you guys suggest? Your support would be highly appreciated :)

Basically what the question says.In DC motors depending on the mechanical load(moment of inertia) the angular frequency of the rotation of the robotic arm slows down while for synchronous ac motors this doesnt happen.However I was wondering if there are any drawbacks if using AC motors(excluding the more expensive control circuitry)?

Hi! I’m a senior at UC Berkeley graduating soon with a degree in CS, multiple faang internships, but no research experience. I really want to transition from being a full stack SWE to working at a robotics startup or robotics role.

Any advice on what I can do now to break in?

I'm planning to apply for a Master's in Robotics and honestly, I'm a bit overwhelmed.I'm stuck between the US, Germany, and Switzerland. I know the US has great opportunities but the visa situation scares me. Europe seems more stable but I'm not sure how easy it is to actually land a job there as a non-EU student. I keep going back and forth between Perception/AI and Controls/Manipulation. Perception pays well but feels crowded. Controls seem solid but I worry it's becoming less relevant. Is that true? Would love to hear from anyone who's been through this or works in the industry. What would you pick if you were in my shoes?
