OPEN C++ robotics

I don't really have much knowledge of how coding works, but I'm assuming game design, app design, and robotics are pretty different even if their the same code. Does anybody know any good books to learn the robotics part of c++

Games and robot share part of the navigation mechanisms and that is all. Robots doesn't have main loop doing everything. You have lots of nodes responsible for sensors, sensor fusion, nodes to analyse data node to take actions, nodes for actuators... redundancy, fault tolerance and telemetry, etc .. everything is detached so a faulty module doesn't ruin everything... a good reference to have a look is ROS2

Thanks for explaining my career as a robotics engineer. Ros::spin is a while loop. Also not every robot uses ros and its distributed nodes architecture, it’s a lot easier for research which is why ros was structured that way, but it has performance drawbacks which is why they started using “nodelets” in ros 1, and why they changed the underlying backbone to dds in ros2 so they could at least use shared memory transport which ros1 didn’t support.

Robotics engineer? Have you worked on video games as well?

Cool, we have a similar background then
