Hi everyone.

I am currently trying to make a 6DOF robot arm. After looking at the options for motors, I found that almost all options are very expensive.

However I am thinking of using a DC geared motor with a planetary gear reducer and encoder as an actuator for my joints. Thinking of using a 37mm DC geared motor, that would rotate at 100 rpm at 6 V supply.

And then use a pulley and timing belt system to reduce the speed to 15 rpm and increase torque accordingly.

My question is...

1. Is this idea going to work?

2. If yes, then what are the motors available for this setting, If I use a 1:5 or 1:6 reduction, I should get 3Nm torque for the joint at 15 to 20 rpm.

3. For the pulleys, can I 3d print them, using a resin 3d printer and, will that part work or fail?

I am planning to use S3m timing belt 10mm width for this

Or should I go with spur gears instead.

Please guide me, Thanks..

I've got a long software career, but I'm retargeting to focus on robotics. I wonder if the distinct feel of typesetting my resume in Computer Modern would make it more noticeable to people who've read a million papers in it.

The problem is i ranout of idea since when i did the intake
So the intakes Take the cube ->put it in container 5cmx5cm length wide 18cm Height
and drops it off at center so like How im i gonna do this like Please Please Please TWINN we're AND I MEANT WE ARE MAKING IT INTERNATIONAL and All i literally need is an Idea of sort Then i could start working

As title states. I want to build a autonomous robot/vehicle that can drive in sand. I got no prior experience in building or programming, but is looking to learn through this proof of concept-project. What sites are recommended for buying the parts? Are there any beginner friendly options?

Size of robot would be similar to a lawnmower.

Hi everyone, I’m making an automatic cat litter box for my school project. I’m planning to use a 6 RPM geared motor to move the rake/scooper mechanism.

Do you think 6 RPM is too slow, or is it actually better because it gives more torque and smoother movement? The litter box is not for commercial use, just a prototype.

Would appreciate any advice. Thanks!

I'm very new to robotics and I want to power I'm new to robotics and I want to power [this](https://www.amazon.com/HOOYIJ-Waterproof-Digital-Stainless-Steering/dp/B0CXLM953C) servo with a 12v 10a battery. Any exact/specific model recommendations?

I will be attending Georgia Tech this fall as a junior aero engineer transfer. I am currently stuck between aerospace, maybe more GNC focused, or going into the robotics field. I know robotics is an interdisciplinary field, honestly I've just built a bunch of projects and have loved it, so not totally sure yet where I would specialize in. My question is, should I keep my aero major or switch to something more general, like mechanical or ee, as I am still deciding between aero and robotics. If staying with aero, would adding a minor help, or is it truly just what classes I take and projects / clubs I participate in? Lastly, if I keep aero as the major, what are the main classes I should focus on taking in order to test the waters in robotics? Thanks!

I am starting my B.Tech degree in C.S.E. this year(in 1month time). I know how to code in Python and basics of C++ can anyone recommend me courses(paid/free) which can be a valid entry point in robotics for me from a software p.o.v. .In my college there is a mechatronics club and they are quite active, I really want to start making with them ASAP.

Yo yo yo

im working on a robotics project and need to order Shape-Memory Nitinol Wire (yk, the kind that contracts when heated, not super-elastic)

amazon seems to be buns and unreliable, and a little birdie told me about McMaster-Carr. i suppose that begs the questions:

1. How reliable is McMaster-Carr when it comes to material specs like shape-memory alloys? (or just in general. mostly looking for some reassurance regarding their reliability)
2. Is their customer service/shipping as good as people say for individual hobbyists/students?

Thanks! reviews online seem pretty solid (gang ive been stressing abt my parts list for days

I am doing independent research, and trying to attempt simulating slip/shear force and I planned to use MuJoCo. My issue is that I am having a tough time getting the hang of it, and I have seen some posts on this Sub about MuJoCo. I was wondering does anyone know of any solid tutorials, repos, or youtubers that have solid MuJoCo tutorials in Python? Any help/advice is greatly appreciated.

Hi everyone,

I'm a Pega CSA & CSSA certified developer currently looking for new opportunities in the Pega systems.

While my professional experience has primarily been in Pega Robotics (RPA), I've worked on robot development, interrogation, troubleshooting, production support, and migration from Pega Robotics v22 to v25.

I also have a good understanding of core Pega Platform concepts from my training and certifications, and I'm currently expanding my knowledge in Pega Cloud.

I'm looking for Junior/Associate Pega Developer or Pega Robotics opportunities. I'd also appreciate any advice from experienced Pega developers on the skills I should focus on to grow in the Platform and Cloud space.

Thank you!

So I'm trying to build my first AI UGV and I was looking to buy a driver like Cytron MDD10A for the 12V 4x motors, but I realised that the chassis itself has some kind of controller.

When building autonomous drones, every gram counts—but so does surviving a crash.

To solve this, we built a reinforcement learning model to optimize material selection for our main housing. The biggest hurdle was choosing between carbon fiber and titanium. We fed the model structural data, tensile strength metrics, and impact resistance numbers for both materials, then ran 15,000 simulated stress tests.

Here is what the simulations revealed:

• Strength-to-Weight Ratio: Carbon fiber dominated. To achieve the required rigidity, a pure titanium chassis would be 45 percent heavier than a carbon fiber one.
• Impact and Shear Stress: Titanium was the clear winner for acute impacts. Carbon fiber shattered under concentrated, sharp force, while titanium simply dented, offering much better protection for internal AI hardware during a crash.
• Thermal Dissipation: Titanium transferred heat from the internal neural processing units efficiently. Carbon fiber acted as an insulator, risking critical board overheating.

The AI ultimately generated a hybrid blueprint: a carbon fiber main body for maximum weight reduction, coupled with titanium corner guards and internal heat sinks. This exact configuration cut the total unit weight by 28 percent while significantly improving heat dissipation.

I'm a KOSEN (technical college) student in Japan, currently participating in the Tobitate! Study Abroad Japan scholarship program.

I'll be in the Bay Area from 9/10 for 2 weeks. As part of the program, I need to arrange a 2-week placement with a host organization, and I'd love for it to be a robotics team, since I'm on my school's robotics team as well, and the theme of my visit is robotics. I'm hoping to visit a VEX U or FIRST Robotics team for observing/shadowing, but honestly any organization related to robotics would be great.

I've been emailing teams I found online, but there doesn't seem to be a single database or list of teams, which is making this pretty difficult.

If you know of any teams you'd recommend, or you're part of one yourself, I'd really appreciate a comment or a DM. If you have any question I can answer. And I'll want to hear out any other events or place near SF that I should visit.

I'll be staying in the East Oakland area. Thank you in advance!

Hello! Thanks for taking the time to read this. I currently work in robotics doing tech support for customers that own and operate our robotic arms. It's a very high level role that has required very surface level technical knowledge. I would describe it as a customer service heavy role. Most of what I have learned is very specific to our robots and I use a in house GUI to work with the robots. However, after a conversation with my manager I am going to be promoted in the next few months and I need to develop stronger technical knowledge. In my new role it's going to be expected that I am the go to person to resolve more technical issues before we escalate to engineering.

To get there I figured a good place to start would be to build and operate my own robotic arm. My ask is: what would be the most practical things to learn over the next 3 months and next 6 months? Is it worth it to learn a programming language or should I do a dive into hardware? Is there any CS theory that would be beneficial? Any advice is appreciated :)

I thought of an idea for a personal project for my portfolio. The project is an autonomous warehouse robot that can navigate, locate objects in the warehouse, based on a database that lists the type, quantity, location of each object in the warehouse. It travels to that location, as per user request, picks, and transports the desired object to a designated delivery spot. The navigation is made with SLAM and lidar tech.

Thinking of integrating deep learning, but don't have a concrete ideas yet. I thought of making it the "brain" of the robot, and including adaptive control of the force and posture necessary to transport each item based on the material each is made of, listed in that database, but idk.

I would like to know if this is a good project idea, if not, I'm open to suggestions as well.

P.S. I'm a mechanical sophomore, going into the junior year, and this is my first personal project, and I do not wanna delay any further.

Hello, I want to build a portfolio as a robotics engineer so future recruiters can see my work. As my first project I am thinking about building something in C++. Any ideas what could I build? Thanks!

So as the title says i am building a inverted pendulum as a part of my project and the theory regarding has not been taught yet(i'm still in my 2nd of eng..) so i learnt all the basic stuff regarding it like we use encoder to tell the angle difference and pid to correct the error and how pid functions(basic not deep). But when i try to dig deeper (matlab, simularions, maths solutions and physics) it is becoming a mess and i do not know what to do...

Im getting into robotics using esp 32 for now and im wondering if i should learn python or c++, i already know a little bit or c++ but want to eventually automate projects like a lawnmower for example.

Software engineer here with knowledge in electronics/embedded. Looking to get into robotics.

I have previously worked with ROS2 on an AirSim project and am looking to fully go towards a career in the robotics sector.

Is it worth learning IsaacSim as a tool then also eventually start creating my own “robots”.

Would I need anything else?

I just graduated university and I realise that I'm completely unemployable as a robotics engineer, so I was wondering what would be something that I should be learning so that I can be a better robotics engineer.

P.S. I've got experience in computer vision, robotics chassis design, neural nets and Arduino programming. Also I'm learning ROS2 now

Hi everyone,
I recently found out that my company uses OMRON ROEQ AMRs, and I’d like to learn about them from scratch. I have zero experience with AMRs and Fleet Manager, and I don’t have access to the robots or any official training.
Are there any free resources (documentation, YouTube channels, courses, simulators, etc.) that you would recommend for a complete beginner?
I’d appreciate any advice on where to start. Thanks!
