11.6. Selecting the Motor Controller

Because the Seg-bot is intended to be a rideable vehicle, I chose to use the Sabertooth 2×25 commercial motor controller (see Figure 11-13). You may recall from Chapter 10, "Lawn-Bot," that the Sabertooth 2×25 can power two brushed DC motors in both directions, at up to 24vdc and 25 amp each, which is plenty for the motors used on this bot.

You can build your own motor controller, but if something goes wrong, it is your face that will likely suffer. As safety is the primary concern here, I would recommend choosing a tested and reliable motor-controller platform.
