Describe your question.

I have TB4 that use create 3 platform. I see from TB4 forums that this platform have issue of 100% utilization in CPU.
It avoids me to continue my work with TB4. The robot have delays in data packets and also it harms the navigation due to the fact it cant avoid obstacles

there is no mention of this in the bug fix list for just released firmware update, so afraid it may still be an issue :(

[sashag1991]

Is there a workaround to overcome the issue? change to other ROS2 version or something else ?
I can't proceed with my tasks because the robot cant navigate properly, it not avoids obstacles.

TurtleBot configuration is not technically in scope for this repository. (The Create 3 robot on its own does not normally consume 100% CPU.) However, the iRobot team is working to reduce CPU utilization in general on the Create 3 robot. We have just released G.5.2 and H.2.2, which reduce core loading by about 9%. Please give the appropriate version for your release of ROS 2 a try (I assume Humble if you're on TB4). I'd suggest following #381 for updates.
