IMHO robotics is 90% mechanical and electronics. The programming part is minor. When someone tells you that you can learn the field by buying a third party device and programming it, they are either lying to you or to themselves. I'd put this one down to "well meaning academic".

Totally disagree. To a very large degree, the mechanics are a solved problem. Robots have all the mechanical capabilities they need to solve all sorts of useful problems. The challenge is figuring out how to control them to do anything useful. That's mostly software. Sensors too, and electronics to run the software. But it's mostly an algorithmic and coding challenge.

ROS 2 is in this uncomfortable place that python3 was in for many years. It's clearly the future. Everybody wants to move to it. But too many of the useful libraries haven't been ported over yet, so people mostly stick with ROS1.

We might be getting close to a tipping point. I hope so. But it's probably still 1-4 years out.

I do think the mechanical and electrical aspects of robotics (ie the mechatronics) are ignored or glazed over when teaching robotics, especially through simulation. One has a new appreciation for how wheels roll on carpet once they try to implement a control / path planning algorithm on a real robot in their living room! It would be valuable to gain these "appreciations" by learning robotics more intimately with real robots.

Not sure where this idea comes from. While certainly important, the biggest barriers to robots being more ubiquitous are in software not hardware. The hardware for self-driving cars, warehouse robots, etc. is not the reason they haven’t made much market penetration.

Do you have experience in the field?
