You could also use a worm gear for Motor B. This will lock the differentical
securely if Motor B is not turning.
Of course, unless you are also using a worm gear for Motor A, your turning
radius while be a little larger :-) (unless you always stop to turn).

| In regard to propelling a robot with both the left and right axles turning at the same speed (or, moving in a straight line): Perhaps this was already suggested, but if not, here is another solution that uses only one differential and two motors, (...)
