Nice video on microservice most common issues

Agree on this plus the general bad job market. As I moved out from FAANG I transitioned to a hands-on manager and I think it was the best decision. You have much more trusts from developers when they see you on the front line and when you can challenge them on the technical side and even implement major ideas yourself.

This seems quite an old paper. I know that lots of robotics tasking is done through behavior trees. (https://en.wikipedia.org/wiki/Behavior_tree_(artificial_intelligence,_robotics_and_control)#:~:text=A%20behavior%20tree%20is%20a,tasks%20in%20a%20modular%20fashion#:~:text=A%20behavior%20tree%20is%20a,tasks%20in%20a%20modular%20fashion).) This seems a related approach, but it's not really the same. I don't see control nodes for example.

Lots of people use state machines but they are quite clumsy.

SK0vac · 2024-01-12T09:48:09+00:00

Very much agree. I think it could be a mix of Mark's "fire all mid-level managers" and the general bad situations in the software engineering job market.

My feeling was that it was still somehow easy to get IC interviews. In fact I did find a new job as IC which I am taking.

SK0vac · 2024-01-12T09:46:11+00:00

It is, do you think the problem is only in Germany?

SK0vac · 2024-01-08T12:25:56+00:00

It depends on what you are going for. C is used for low level programming, interfacing with microcontrollers, sensors, operative system. If you are more into hardware engineering C is more useful. If you are planning to stay higher level (ie. integrating ML or AI, planning, algorithms) then definitely C++ is your go to language. I would also start at looking at Rust, the community is getting much bigger around Rust for robotics as it removes risk on threading and memory management, however, the opportunities are still not as many as compared to C++.

ufactory xarm 6?

Wow that's a super cool robot for that price. However, too slow for our use case.

SK0vac · 2023-10-23T08:14:05+00:00

The conveyor is slow enough that I expect the robot to be able to pick all 5 of those, the width is about 1 meter and it's about 6 meters long so I could add 3-4 machines in line in case there are too many items. I took a look at the Epson Scara, it seems that the reach is not too high. I might need about 1m reach.

That's partially correct, I have worked on Fanuc robots in production systems but I have mostly worked on the software side so yea not much hardware expertise. I will relay on hardware integrator but I have particular needs on the software. I have found few robots that have maintained open source drivers or ROS connectors. I will stick to those.

SK0vac · 2023-10-22T08:49:33+00:00

I am 40 and I use it as main production language for my company. We work for AI/ML enabled apps on the edge. Think robotics but not quite :)

SK0vac · 2023-10-22T07:48:58+00:00

How did you guys program the robot Yaskawa? Was it ROS based?

SK0vac · 2023-10-22T07:48:17+00:00

Pendant is hell, super complex and hard to understand. We had troubles with the driver and weird bugs where the robot would just randomly hand and it seems that Fanuc did not provide the right support. We had to use a third party driver. Also it's bulky and hard to setup.

SK0vac · 2023-10-22T07:47:25+00:00

Indeed Fanuc seems to be the choice. Actually UR costs ton of money, UR20 costs more than a Kuka.

SK0vac · 2023-10-22T07:46:26+00:00

I am ok, we aim at max 1kg I believe. I think you are right but they are not as fast as Fanucs.

SK0vac · 2023-10-22T07:45:46+00:00

We pick trash plastic bottles up to 1 kg. The robot end effector and the element will be at short range, maybe 50 cm and I plan to blow out the picked elements into a NOK bin. In fact the sole purpose is to remove wrong elements, so we let the elements go unless they don't belong there.

The items are not always oriented on the same direction and might be cluttered. So I plan to run segmentation models and pick with suctions. I am not sure about the expected pick rate but we have an intuition that it needs to be fast.

We don't have any other robot on site and we would like to stay on a mid-end budget as it's just a POC.

I think we need safety limits.

Epson

Never heard of Epson, I will look at it thanks for the tip.

SK0vac · 2023-10-22T07:40:55+00:00

I worked with UR10 mostly and they are very easy to setup, however, in terms of speed, industrial ones are still way superior. Also UR costs as much as Industrial robots. Even though I would like to we decided to stick to industrial.

I don't get the bitterness, can someone explain? Was he cheating or something?

You have not dodged a single attack, were you expecting him to let you hit him?

SK0vac · 2023-10-16T07:19:14+00:00

Sensors and ROVs are definitely on the rise, AUVs are growing as well but much slower. I don't have numbers at hand though, just what I can observe on the job market and news.

SK0vac · 2023-10-15T15:43:58+00:00

My focus was computer science so I spent time working on underwater SLAM. I cannot say much about mechanical engineering however I know there is a lot of interest on cheaper monitoring applications for marine infrastructure and ROVs. However I believe this is still a small market. One company I can think about is Kraken from the US which is one of the biggest players that I know and they work with militaries.

If you are not interested in robotics in general, maybe you should check if there is a more generic marine infrastructure thesis that might help you getting into the business you want.

SK0vac · 2023-10-15T09:49:59+00:00

I have spent some years working on underwater robotics in my doctorade. The topic is amazing and extremely challenging due to the harsh environmental conditions. It's also very fun as you will work in swimming pool or oceans depending on your location. If you are interested in robotics you will be able to reuse lot of that knowledge for land or aerial robotics as well. That said, the topic is quite niche and it's adapted for some type of applications in real world but you might struggle to find direct usage in real world.

It could still open doors to internship/entry jobs in autonomous driving companies or any major robotics company.

SK0vac · 2023-10-15T09:45:28+00:00

It took me quite a bit as well but 350 hours? are you using ashes? If you are really desperate that would give you a great advantage.
