Robotics Distributed System based on Kubernetes

One question I have, for a single Robot that is an Edge cluster that consists of multiple Nodes, is orchestration necessary?

I would not say it is necessary. But using orchestration, I think there would be advantages such as maintenance, robustness and service availability. Our target is distributed system, so that it is not only for single robot like ROS1 but ROS2.

Is orchestration primarily coming into the picture when there is offload to an on-premise Edge Server or Cloud.

I believe so. that is one of the focus.

is there a way for us to discuss offline?

I am willing to do that. Could you send me a PM?

we’ve been investigating KubeEdge also, that works okay and it is built on top of K8S API, so that we can use KubeEdge and Kubernetes at the same time in the same cluster. We actually did contribute the kubeedge-counter-demo

Nice!

@tomoyafujita

there is also K3S , Lightweight Kubernetes . Production ready, easy to install, half the memory, all in a binary less than 100 MB. That works well too.

Yep, I’ve played around with it already. Was fun to play with.

There is another lightweight Kubernetes: microk8s (Apache-2.0).

Hi @tomoyafujita,
I stumbled across this guide, which seems really promising. I’m also very interested in this and would appreciate it if a second updated talk could take place and join you.

thanks, and just for your information, we’ve been already developing some ideas.

here is the presentation slides for KubeCon2021 EU Edge Day.

we are open to discuss
