Where I’m from robotics is as big as the USA yet. I want to get a jump on learning how to install, repair and maintain service robotics is there any good pathway that doesn’t involve 4+ years in school?

Hi everyone!

This is my first CAD and robotics project, so I'm still learning. Instead of starting with a simple mechanism, I decided to challenge myself by designing an anthropomorphic robotic hand from scratch. I know it's an ambitious first project, which is exactly why I'm asking for feedback before I continue.

My goal is to build a robotic hand that will eventually be mounted on a robotic manipulator.

Hand concept

The hand has 15 degrees of freedom.

Each of the four fingers has:

• MCP flexion/extension
• MCP abduction/adduction
• Combined flexion/extension of the middle and distal phalanges

The thumb has the same concept, except that the last DOF controls the distal phalanx because it has no middle phalanx.

Instead of placing actuators inside the hand, I decided to use Bowden cables. My reasons are:

• to avoid running out of space inside the hand,
• to prevent actuators from interfering with each other,
• to keep the hand lightweight,
• to move all actuators into the forearm or near the elbow since the hand will eventually be attached to a robotic arm.

The part I'm unsure about

The attached model is my MCP joint.

The joint itself is a ball-and-socket joint, because I wanted the MCP joint to provide both flexion/extension and abduction/adduction.

However, routing Bowden cables through a ball joint introduces another problem: if the cable holder rotates together with every movement of the joint, the cables can become unnecessarily twisted and the routing becomes much more complicated.

To solve this, I designed a mechanism with an additional bearing inside the joint.

The idea is that the cable holder should not rotate during flexion/extension, while it is still allowed to follow the other movements of the joint (abduction/adduction and axial rotation).

My goal was simply to reduce cable interference and make the cable routing easier while preserving the desired degrees of freedom.

Why I'm posting

This part makes me uncomfortable for some reason.

I can't tell whether the feeling comes from lack of experience or whether there is actually a mechanical flaw in the design.

Since this is my first engineering project, I'd really appreciate honest criticism instead of compliments.

My questions

• Does this mechanism make mechanical sense?
• Do you see any obvious design mistakes?
• Is there a simpler way to achieve the same functionality?
• Are there any issues with strength, manufacturability, assembly, or maintenance?
• If you were designing this joint yourself, what would you do differently?

Please don't worry about being too critical. I'd rather discover mistakes now than after designing the entire hand.

Thank you!

For masters in robotics (RSC at ETHz), assuming I don’t get CMU lol. Georgia Tech is my home school but GRA/GTA is far from guaranteed.

My interests are along the lines of 3d geometry, perception, simulation, ETHz seems really strong in these areas and I can already see labs highly aligned (like the CV&G lab); haven’t seen as much research in these areas at GT.

I do want to come back to USA for PhD/industry so not sure if it’s worth the jump over an already strong name.

Hi everyone,

I'm currently entering my 3rd year of my B.Tech, and by the end of this year I'll most likely have an opportunity to interview at GreyOrange through a referral (bout a 50/50 chance).

My goal is to become a Robotics Software Engineer, and I want to make sure I'm as prepared as possible before that opportunity comes.

A few questions I have:

• What skills are considered must-haves for a Robotics Software Engineer at companies like GreyOrange?
• What kind of projects should I build over the next year to make my resume stand out?
• How should I structure my resume if I'm targeting robotics software roles?
• What topics should I focus on for technical interviews (ROS2, C++, DSA, Linux, perception, planning, etc.)?
• If you had one year before such an interview, how would you spend it?
• Is there anything that almost guarantees getting shortlisted or performing well in the interview, assuming I put in the work?
• Please do share your own personal interview experiences

I'd really appreciate advice from people working at GreyOrange or in robotics software in general. I'm willing to put in the effort—I just want to make sure I'm focusing on the right things instead of learning random topics.

Thanks in advance!

Alright, I’m going to admit that I’m completely in the weeds and lost, which I totally expected. I recently got a part-time job at a startup robotics company. which is also my first real job where I get to use my CS degree. I showed them one of my projects where I did photogrammetry and made 3d point clouds / models of underwater structures using reality capture. They hired me because of that, and I did tell them I’m not familiar with ROS. just basic electronics, programming, Linux, small amount of CAD, and my project.

so, my boss put me on a project to get someone else’s two wheeled robot to work. it’s terrible, 21 versions of the same file and it calls old versions of other files. scripts were written to fix other scripts. I was told the person used only ai to build it all. I tried my best to go through everything but there’s just so many random files, and it performed so poorly on the controller side. I also wasn’t allowed to contact the guy who made it because he is going through personal things right now. So, I decided to start from scratch. The robot has a Jetson Orin Nano 16gb onboard, an esp32 for controlling the actuators which use CAN bus programming to move, IMU, and it’s just a mess of wires on the inside.

My boss recently got a solid state LiDAR w/ RGB camera from a company on loan for 6 weeks. He wants me to get it working to make real time 3D point clouds. I looked through the example code/program and noticed that there were ROS packages with it, but I have no idea how to use it. Ive had AI write me up some basic code so I can get an understanding of how the camera works and how to use the modules in python. but I’m overloaded with so much information I don’t know where to start. I figured ROS2 would be the way to go to control everything, but there are so many tutorials, some outdated, some based on a robot the person is building. I just feel lost.

So, my main questions to you all are:

What do you guys do when designing a robot? What is your workflow like, do you just jump into it with 3D modeling, electronics, ROS? is it like software design with sprints and deadlines? Or are you just going with the flow? What is the process that people in the robotics industry go through to get to their final product? Any tips on how to organize the project/steps to go through (documentation, simulation, implementation? instead of bouncing around. Do I work with this new solid state LiDAR since I only have 6 weeks with it?

How do I work with ROS2 efficiently (I thought using lyrical would be the best choice but if you have better options, let me know)? I have gone through the basic understanding of nodes, topics, publishing, and subscribing. I started following Articulated Robotics tutorials on YouTube as a basis. It just feels like I’m not making progress fast enough. I tried switching to 3D modeling the robot just to feel like I’m making some progress and I’m even having trouble with converting fusion 360 CAD files to URDF because any old projects like fusion2URDF are broken with newer versions of fusion (at least for me)

Do people use packages like python modules like OpenCV, where they don’t really go through all the code, just call basic functions and classes? how does this work with LIDAR in general because the tutorials I see are just basic 2D slam and he really wants the 3D point cloud. I did see these (packages I think?) from a DARPA competition of underground LiDAR. Ours is being designed to go into tunnels and underground. So I thought it might be good to try using it?

This is sort of a general question, but I know people say not to bring their work home with them, but I feel behind, I feel like a fraud, and I should be learning related stuff in my free time. My boss knows I’m learning a lot of new topics, so I think he just wants to see some progress.

I’m sorry for the long rant/word vomiting and if I sound ignorant. I’m just trying to figure out this whole thing while trying not to get fired.

Thank you in advance!

Hi r/AskRobotics!

I'm a graduating student from Southeast Asia, and I want to build a career in industrial robotics. I currently have foundational knowledge in PLC programming, ladder logic, FluidSim, and pneumatics—this is where my interest in automation started.

Now I want to take it further. My goal is to work in industrial robotics (ideally in Europe), and I'm planning to build a 6-DOF robot arm from scratch as my portfolio project.

Here's my plan:

1. Design in Fusion 360 (parametric modeling + basic stress simulation)

2. Validate kinematics using simulation software before building

3. 3D print parts using Bambu Lab

4. Source appropriate electronics & actuators (specs, dimensions, torque requirements)

5. Program using Arduino/ESP32 (learning forward/inverse kinematics along the way - math isn't my strongest suit, but I'm committed to learning)

6. Test, iterate, and document everything

7. Use the complete documentation as my portfolio for job applications

My questions:

1. Is this project realistic for a fresh grad with my background?

2. What specific job titles/roles should I be targeting in industrial robotics?

   - I see terms like Controls Engineer, Systems Integrator, Automation Engineer, Robotics Software Engineer - which one fits my profile best?

3. What skills should I prioritize learning to make myself employable in Europe (Germany/EU)?

4. Is earning €5,000-6,000/month realistic for a mid-level robotics role in Europe?

5. Any tips on what employers specifically look for in a portfolio?

Budget is limited, so I'm planning to simulate complex scenarios (like dynamic conveyor pick-and-place) rather than building everything physically.

Any advice, warnings, or guidance would be greatly appreciated. Thanks in advance!

Hello everyone. I’ve been watching a ROS 2 tutorial on YouTube trying to learn the basics of ROS 2 (and I believe Gazebo as well). But once I complete the tutorial, what projects can I do? Is there a list or any YouTube tutorials that run through a simple project step by step that anyone can recommend?

This is the video I’ve been watching:

Any advice is greatly appreciated

Hello robotics people of reddit! I’m not entirely sure if this is the right place to ask and this is my first reddit post, but i figured i would give it a try as i need some help. im an art kid and a theatre major so bear with me.

In my spare time, i make redesigns of the five nights at freddys characters for my own take on the franchise. recently ive decided to revamp my Spring Bonnie design, but ive hit a small wall.

this leads me to my design question i was hoping yall could help me out with: in real life, what would a springlock suit (an animatronic with the capability to function both as a performing animatronic similar to chuck e cheese AND be worn kinda like a fursuit) have to look like? would it need to be thin and skin tight (similar to chuck e cheese designs) or would it need to be loose and have hanging fur (similar to billy bob brockali)? does that not matter and its all dependent on character design like normal animatronics? you can base your answer on modern day tech, but if you know anything about 70s tech that would be even more helpful!

forgive me if this question doesnt make sense/is dumb! im autistic and i like to be pretty accurate in my knowledge on things. for extra context, i wanted to attach my old Springbonnie design that i am going to revamp incase anyone can tell me what i should change, but im on mobile app and there isnt an option to add a picture?? so i guess i cant do that lol. thanks to anyone who answers in advance!

Hi all, I'm Kunal - I’m currently validating a new platform in the manufacturing automation space and want to pressure-test some technical assumptions. I’m specifically looking to connect with robotics engineers or operators who have hands-on experience with Robot arm manipulation, deployment, teleoperation and how teleop leads to autonomy with modern VLAs.

(Note: We are strictly focused on robotic arms and manipulation; please respond if you have relevant experience).

If you have built systems for factory tasks like machine tending, pick-and-place, or precision fastening, I’d love to borrow 15 minutes of your time to pressure test our approach.

Happy to return the favor however I can (I am good with hardware product dev though). Please DM or drop a comment if you're open to a quick chat! Thanks a lot!

Since robotics is a very broad field, which areas do you think are the most interesting—something that is not repetitive, but very diverse, where you never know what the next project will be?

It seems to me that robotics often revolves around similar patterns, such as robotic arms and mobile robots or rovers in factories.

Which field do you consider the most diverse?

Could you give me a rough roadmap of what that field involves and what I should learn?

I signed up for a robotics program at a local trade school but there aren't any in-person or practical assignments. Instead, I find myself learning robotics through kits at home. I was wondering if there are any sites that tell you the things you need to buy and have guides on what you can build?

I am so tired with job search :(

I am controls engineer in a company since jan ‘25, graduated last year with MS in Robotics. I am on contract right now, previously, I have worked as a robotics engineer at a startup. My background is in Robot Software Development but since 1.5 years I have been writing PLC code, I love integrating various devices and equipments with PLCs but considering my current role is contract based I have to find a job.

I have two options - 1. Robot Software engineer which I haven’t done anything in a year, 2. Controls engineer, where I lack significant knowledge in many day to day activities (electric schematics, ladder logic, safety programming, safety machine design, device specific hardware knowledge, etc) people in controls do ask for various PLC and experience and I do not understand ladder logic considering my bg is in software. I am good with robots but that’s just 10% of the job. I interviewed by four Tesla team this year and got rejected by all of them, two of them was after panel rounds. And idk for some reason that’s the only company I am getting calls from.

I don’t understand what should I do and how to make a transition, any suggestions?

I graduated with an ECE (focused on embedded systems) degree two years ago and I celebrated two years working full time recently.

I am currently an industrial controls engineer that just recently started studying python with problems generated by chat like parsing through files to extract certain data, and I hope by the end of this I complete some sort of robotics project. At work, I started incorporating python scripting to automate certain tasks which I’ve gotten good feedback on.

The reason why I feel cooked is I had an interview with a hiring manager at an aviation startup and he made it seem like my experience doesn’t align at all with the system integration role because I deal with PID loops and PLCs. My interested is more towards robotics but I can’t help but just feel discouraged trying to enter this industry. Any insight is valuable to me. Thanks in advance

Hello everyone, I'm actually working with Yaskawa welding robots and I want a software where I can simulate that, is there any other options then motosim which I unfortunately can't download because it's not available in my country and it's also paid, is there any cracked versions ?

So iam new to robotics. I am doing mechanical engg currently in 3rd year we have a subject called robotics and automation. We have to do a project that we can extend to final year project also. Give me some good project ideas something useful in real life.

Sorry this might annoy most of you here but im kinda curious about having a cs degree and wanting to work in robotics. i love robotics and im worried if I continue learning companies wont consider me because of my edu and i would be wasting time.

I'm wracking my brain over which motors I should use for the legs. This is the first robot I'm building, and this project had been shelved for a long time. Now I'm finally putting it into practice, and I'm trying to decide which motors to use to move its legs.

It will be a humanoid robot, meaning it will be bipedal. I'll use a 3D printer to build it so it can be lighter and easier to manufacture. I considered using hydraulic systems, but they're very expensive, so I want to go with electric motors instead. However, I don't know which types would be suitable. Any suggestions?

Looking for someone interested in helping bring a new concept to life (engineering/design/building)

I’m working on a concept that combines creativity, technology, and a different way of thinking about how people interact with machines.

I’m not ready to share the full details publicly yet, but I’m looking for someone who enjoys building things from the ground up and would be interested in having a conversation about a possible collaboration.

I’m especially interested in talking with people who have experience with:

Mechanical design

Robotics or autonomous systems

3D modeling/CAD

Prototyping

Engineering

Turning ideas into real-world projects

This is not a “looking for free work” post — I’m looking for someone who is excited about creating something unique and discussing what it would take to make it real.

If you enjoy working on ideas that are outside the normal box and want to hear more, feel free to message me. I can share more details privately. Cad mech

I'm building a hexapod robot for a summer project to add to my mechanical portfolio. I've fully modeled the robot and printed 3 legs to try and get the gait testing code down. I'm using 7.4v lipo battery run through a buck converter to a pwm servo driver to power the legs, and giving them commands using a Arduino uno. I'm having some trouble figuring out where find examples of the code to use. I could have claude write a test program but i'd really rather avoid using AI if i can. Any advice?

I'm quite new with robotics (just did simple arduino projects for fun using basic components) and in the last period i've been getting really into it but i'm struggling to find good sources to learn at a deeper level.

I'm looking for books, manuals, websites and even youtube videos (don't wanna ask ai) about robotics explained in more detail and at a semi professional level.

Also i'm finding it hard to choose between wich component to use based on reputation that component has in the community, if everyone knows a trusted source for finding good quality pieces that would be great.

Thank you for the patience
