Hi there,

I want to ask if it's worth it to program the robot without openCR for things like odometry, movement, imu, etc?

you do not need the openCR but if you like to drive fast, or realy precise then you need a peace of hardware with an rtos (any bigger mcu) or you program it barematel.

you may look at https://micro-ros.github.io/ to have somethink like ros inside of the mcu.

then it depend witch kind of motor controller you use. if it is a good one you need les realtime see here https://roscon.ros.org/2015/presentat...

The robot is in an indoor and stable environment, it doesn't need to move really quick (approx 0.5 m/s) and its using three dynamixels and two 2D lidars.

No

This depends on how you define "worth it".

I'm assuming, you mean this with openCR. There are many robots out there that don't use this module. Thus, my answers above.

If you have more specific questions or concerns, please elaborate.

Yes, exactly, I want to ask what are the advantages of using OpenCR in your opinion?
