| Jun 13, 2016 at 23:24 | comment | added | Chris Stratton | 6 volt motors expected to be well under an app would probably point to a TB6612FNG. Some of the newer motor shields use those, as FET devices they are much lower loss. | |

| Jun 13, 2016 at 19:24 | comment | added | shurup | @IgorStoppa I was looking at buying something based on L298N. Thank you for warning me. Now I will probably get the one you advised. The one I was previously planning to get: ebay.com/itm/… | |
| Jun 13, 2016 at 19:20 | comment | added | Igor Stoppa | So far, the driver I linked seems to be ok. I do not have experience with the one from Sparkfun. But I can advice to not buy any based on L298N because of the much higher internal power loss: ebay.com/itm/… | |
| Jun 13, 2016 at 19:16 | comment | added | Igor Stoppa | @NickSolonko when dealing with motors, you laso have to account for peak current consumption: overcoming the initial inertia will draw much more current than when steadily cruising. In general any change of speed (including steering) will cause a temporary increase. | |
| Jun 13, 2016 at 19:16 | comment | added | shurup | @IgorStoppa Do you recommend getting the Sparkfun driver or did the one you got from ebay work fine? | |
| Jun 13, 2016 at 19:10 | comment | added | Igor Stoppa | If you want to add a feedback loop to each motor, I found these optical end stop detectors to work quite well: ebay.com/itm/… | |
| Jun 13, 2016 at 19:00 | comment | added | shurup | @IgorStoppa Each motor draws 120mA at 6 Volts. I have read about people controlling 2 motors together. I will probably control them individually so that I don't risk anything. | |
| Jun 13, 2016 at 18:34 | comment | added | Igor Stoppa | In theory, it's true that the 2 wheels on each side could be controlled by the same driver (assuming it can output enough power), however I'm not sure how this would play out when motors are either not sufficiently similar or subject to different load (say one has to overcome a small bump). So I preferred to play it safe and have each wheel controlled independently. | |
| Jun 13, 2016 at 18:31 | comment | added | Igor Stoppa | If it can help, I have some code I'm using exactly for that purpose: github.com/igor-stoppa/ChibiOS/tree/car I haven't had much time lately to spend on it, but it does the basic. I'm using 2 of these: ebay.com/itm/… | |

| Jun 13, 2016 at 17:07 | comment | added | Majenko | Each motor needs a driver. If a driver board can drive two motors then you need 2 driver boards for 4 motors. If a driver board can only drive 1 motor then you need 4 driver boards for 4 motors. Find a driver board that is powerful enough for your motors and then do the (very simple) maths. | |
| Jun 13, 2016 at 17:06 | comment | added | shurup | @Majenko would I have to use 2 drivers then? | |
| Jun 13, 2016 at 17:02 | comment | added | Majenko | Use motor drivers that aren't on a shield. | |
