2019-09-09 09:39:45 -0500	commented answer	Expected behaviour when cmd_vel == 0 Thank you for such a detailed response. This is exactly the information I was looking for, and it makes perfect sense.
2019-09-09 09:38:35 -0500	marked best answer	Expected behaviour when cmd_vel == 0 I've just finished writing a hardware interface for my custom robot. It finally performs as hoped, but I'm not sure what `cmd_vel` == 0 m/s should actually cause. Does it mean: Stop powering the robot's wheels, allowing it to coast downhill (i.e. robot is not powered) Hold the robot still, as if it were being actively braked (i.e. robot velocity = 0 m/s) Maybe it's just personal preference, but I am very interested in hearing what the ROS official convention is.

2019-09-09 08:46:59 -0500	commented answer	How can I convert PWM values to velocity? After encoders are added, you will also end up needing PID controllers to correctly transform effort into velocity.
