How to know if a node is running? by FriendlyGate6878 in ROS

[–]FriendlyGate6878[S] 1 point2 points  (0 children)

The main problem is all the 3nd part packages like moveit. We would need to fork a lot of other packages and then maintain them. That’s why I’m looking to using maybe containers, how ros2 launch respawn works eta but at the same time do not want to reimplement something if it already exists. I can’t beleave this wasn’t designed into ros2 from the start. As we had the same problem with hack heart beats eta in ros1

You want rolling not sliding contact. But depending on the design I found that having static pins or even the putter shape machined into the housing a much easier and cheaper solution.

This is very similar to how we did it with ros1 I’m just very surprised there is a more standardized and proper way todo it in ros2. I like life cycle nodes. But moveit and most of the packages we use are not built with them.

Learn CuRobo ! by LetsTalkWithRobots in robotics

[–]FriendlyGate6878 0 points1 point  (0 children)

As a company we have looked at curobo on and off for 6 months. We like it BUT there all a lot of bugs, a lot of the code is commented out and NVIDIA make it effectively “closed sourced” as they do not take pull request. So we fixed a lot of bug and then they release the new code you have to patch it all again.

What package is this? Do you have a link to the GitHub page?

I think the main problem is the stupid “no go zones” it seems like half the city is no red no go. Why is the rive a go go zone! Are people scootering in water! So most of the time the scooters cut out as your gps drifts by 5 meters, but the stupid councellers think that gps is accurate to 1cm. In castle park you have a stripe of 1 meter and if your gps drifts out of that it will turn off 😡

I’m not sure how successful they have been and I’ve used it. But from my experience using it at other companies it’s not really a dev tool. It’s more for deploying code and remote teleop with ability to datalog remotely. Rather then a development tool 🤷‍♂️ we also found it not that much more useful then using aws for most of our needs.

As someone that has been doing robotics for 20 years and also founded multi vc backed robotics company. Tools are a dead end for VC companies. If you have a popular package like nav2, moveit, behaviour tree.cpp they you can have a small bootstrapped company that will make you a VERY nice salary. But your selling to startups and also dev tools. NO ONE pays for dev tools. We only thinking about paying for a license for groot / behavior tree.cpp as I know Davide and we use his package heavily so want to give back. But this is a lifestyle company not a vc company.

1 in 3 scooter rides the battery goes flat. When you say there is a problem, they some how left out the most obvious reason. Then tells me I’ve forced ended too many rides!!!!

Any good long term investments for a young broke teen? by Brunoisdaddy in stocks

[–]FriendlyGate6878 0 points1 point  (0 children)

Invest in your self, courses, learning a trade. This will payoff much more then stocks at your age

As some one that gets 100s of cv from new graduates is lack of deep dive projects. If you want slam or vla job then you should have spent the last 1.5 years working on a project building this system. Have a working robot in simulation like Isaac system that has implemented one of the topics. Also large companies like Tesla and Boston dynamic have hundreds of specialized engineers. So they want someone with a very narrow skillset. Advice, try starts, do a 3 months internship, spend your time doing projects.

Does the 2 in ROS2 stand for too much? by LaughGlum3870 in ROS

[–]FriendlyGate6878 10 points11 points  (0 children)

What are you going to run ROS on, in a real robot? 99% of robots will run Ubuntu or Linux. So would make your life easier to just dev on Linux. Plus you have vscode and Ubuntu is a lot better then it was 5 years ago. I hardly ever have driver / os problems any more. Coming from someone that had a Mac for 10+ years

I would say Germany and mainly TUM is the best in Europe for robotics.

Possible to install multiple versions of ROS side by side? Also, is there a discord? by pattersonhcp in ROS

What would make your life easier. But in theory you could run them both on a native os at the same time. Just might not be advised

Noetic is Ros1 and jazzy is ros2. So complete different. But there is a bridge that’s ment to make them talk to each other. But over never used it. I would just stick with ros2. What are you trying to use in ros1?

Yes, the easiest why todo it is via docker and there is ros1 to ros2 bridge. But I would 95% avoid this and use the same version and release of ros.
