Two H-Bridge driver daatsheet control the power to each motor. One supervisory driver controller will send control signals to each of the two H-bridge drivers.
Good overview of the theory here: OTC high-current motor drivers are pretty much unaffordable. So we’ve pretty much settled on the “open source motor controller” design. Here’s the Yahoo home page: The hrf325 FETs are the most expensive parts.
We need 8 per board, and two boards per urf3205, so they add up fast. There are three recommended ones, in order of decreasing cost:.

We will test them on a heavy load, and see how hot they get with heatsinks. The more expensive has lower Rds, and the TO package is pretty much limited to 75A of sustained current for thermal reasons, so it will be interesting to see if there’s much performance difference. There is also the http: No wonder they are out of stock: No wonder they’re sold out.
As Pete points out, sensing load current is non-trivial depending on drive mode: Jon likes these hall-effect sensors over shunt resistors: Retrieved from ” http: Command and Control System.
