For a while new grads had a severe lack of hands on ROS experience. Though many companies don't use ROS, it is so entrenched in the industry that most solutions look similar enough for transferrable skills. (Src: was hiring mgr in robotics) Highly recommend if you want to get into robotics you have ROS experience and demos / stories at hand.

I'm really intrigued by robotics as future career. How would you rate it for the next 10-15 years? I'm seriously thinking of investing in a masters degree focused on robotics (CMU). I'm close to 50 and already have a cs PhD. Just intrigued by it and feel it might have a longer career (when it takes off).

Robotics is already taking off. It’s just not evenly distributed. I think several companies are being highly optimistic in their projections of millions of humanoid robots in five years. But, I think it’s the common mistake of overestimating the short term and underestimating the long term.

Based on the Andino robot project [1] the price is greater than USD 250 [2] I wonder how far we can push the price down for schools. For example, putting an [old] mobile phone (with a camera and replacing the battery), and moving to ESP32 and use another OS.

I suffer it so much every single time I have to interact with it that sometimes I really really want to do something else, but I can't. Unfortunately is not my call, is part of my job. I have already made my opinion about ROS in a previous thread, but another user synthesized it very clearly: it's a trainwreck. Now we can be more precise: it's an academia trainwreck tool.

Robotics is a very hard topic. If on top of that you add ROS which almost everyone is using you will end up very disappointed and without much enthusiasm to do robotics at all. My major criticism to ROS is that because robotics is already hard, ROS does not make it a single bit enjoyable or easy, all the opposite as a matter of fact.

What is your opinion of ROS? I can’t find the previous thread you mention.

Trust me, having your own crufty cobbled-together robotics code base that gets more and more insipid over time is way worse. 10/10 would start anything new with ROS.

ROSCon Macao, 2019. As a time hack (our food robotics R&D facility, the "Noodleplex", was right across the border) I dragged all the academics down to the best bar (little resistance offered) instead of attending. While an interesting set, I was gobsmacked how little industrial nous attendees had and came to form the opinion that ROS use goes hand in hand with a "ROS can do CV ... everything is a nail" mentality. CV is a niche tool. Deployed, commercially relevant engineering generally uses something else unless the explicit system goal is visual input, because something else is always faster, cheaper, more reliable and has a supply chain stability half life greater than six months.

We replaced ROS with GRPC, foxglove and our own code. Works reliably, much better to handle. Would recommend everyone else to try it

Can you explain what ROS does/is to the uninitiated? Why is everyone still using it if its such a trainwreck?
