Position, velocity and current/force are the currently supported modes, see: https://github.com/madcowswe/ODriveFirmware/blob/master/Moto... Coming soon will also be go-to commands which track 3-rd

The hobby outrunners come in both varieties: the cheaper ones are surface magnet ones, like this one: https://hobbyking.com/media/file/1010923149X745660X9.jpg and the slightly more expensive ones have the magnets

One thing to keep in mind is that for many robotics applications, the duty cycle for high torque (i.e. acceleration) is often quite low. So they may still run fairly cool.

I have compiled a small list of motors that I think are suitable for robotics applications, along with some useful calculations, here: https://docs.google.com/spreadsheets/d/12vzz7XVEK6YNIOqH0jAz... You can take a

Thank you! 1. Thanks for the suggestion, I have DB-DTFC to my motor control theory bookmarks. There are a few reasons I am sticking to FOC for now. The main one is that it is, as you say, the more standard one used, and hence there is more

So this product is still in development. Hence the hardware is ready for regeneration, but right now the firmware doesn't support it yet. In principle it works by just putting a high charge current capable battery on the DC bus, and si
