Could somebody recommend some motor controllers already tested it with ROS? I'm looking for motor controllers that inputs 48v 1000w, supports CANopen CiA 402 and been tested with ros_canopen package.

Therefore, you'd have your microcontrollers receive serial messages and then send them to the motor controllers/etc . in an format that the hardware is able to understand while programming happens without ROS. ROS framework. (Unless I create ROS nodes with micro-ROS, and then flash it directly to the microcontrollers? Still unsure what I/O will be used in this scenario.) Thanks for the links and keywords. Gives me lots of information to look into!

In my search for hours I've come across a variety of instructional videos for creating and operating a robot using Gazebo for use as a physics simulation however, there's not one that implements this in hardware. TurtleBot3 is a possibility, however it appears that the most affordable version is priced at $500... I would like to know what project was created using a brief BOM and some 3D-printed parts to give me some hands-on experience.

Please don't "answer" when it's not an actual answer. Instead, you should edit your description using the "edit" button at the end of the text, then add whatever additional things you want to say.

You could use maxon EPOS4 controllers, they are CiA402 and work fine with ros_canopen. There is a large range of products so you'd have to chose one that can accept 48V, for example the EPOS4 Compact 50/15 CAN.

I made two tutorials on the ros_canopen page itself that you can use to get some basic demo working. You can also find a sample ROS package and more complete documentation here.

Feel free to open new specific questions here on ROS Answers if it's related to ros_canopen tutorials.

It seems the Elmo Whistle Gold supported and tested with the canopen_402 package fits your bill.
