If a data connection to the input port exists the controller sends old data as new commands even if no new input samples are available. This results in a dangerous behaviour commanding the robot to move without any timeout. The new implementation repeats the command until a timeout interval passed. After this stop commands are sent until a new input sample arrived. This ensures that if the commanding component freezes or forgets to send a stop command the robot stops after n seconds.
base/MotionCommand2D is the old name and currently a typedef for base/commands/Motion2d. MotionCommand2D is going to be removed from base/types
