Ironknight zero asked How to change polarity of a motor with one command source?

The motor needs to be connected to a power source which would be actuated by a wirless command. But, that actuation would cause motion of the motor in one direction only, how do i reverse the direction?

And got the following answer:

Assuming this is a small DC motor with permanent magnets, it can be reversed by reversing the supply polarity. The remote control receiver device will presumably have more than one digital output channel that can be turned on and off. These outputs will operate a switch or relay to: a) Power up the motor (on/off) b) Reverse the motor. The reversing relay is operated using a driver transistor connected between the remote and the relay coil (see second link below), and needs 2 changeover contacts to reverse the supply polarity (see first link below). These must be break before make contacts, so the supply is not shorted as the relay contacts change over. A second method is to have two channels as above, but use one for on/off forward and one for on/off reverse. Some sort of interlock is required to prevent it being switched to forward and reverse at the same time. This logic can use diodes, transistors, integrated circuits, or relays. A third method uses two power supplies with a half bridge circuit using transistors to connect one or the other supply through the motor to the supply common. A fourth method uses a H bridge using 4 transistors to reverse the supply to the motor. You can look this up if interested. If the remote has only one output, it may be possible to use a sequence of pushing the button, like first press on, second forward, third off, fourth reverse, fifth off, sixth back to 1 again. This uses a counter and other electronics. Garage door openers use a variation on this, with a single channel control, where the motor controller choses which direction to move by knowing the current position, and limit switches control its range. If it is closed it opens, if it is open it closes, and if it is in between it continues if stopped or stops if running.
