Conclusion
Motion control options for robotics range from basic, dedicated-function ICs
to highly integrated, extremely flexible MCUs with a large array of auxiliary
processing and support functions. Although embedded devices may seem
limiting, some of them allow selection of a variety of motion profiles and setting of
critical parameters, and they are quite adequate, have low cost, and are easy to
use. For advanced designs with unique or extremely sophisticated requirements,
or designs needing additional levels of connectivity along with control, MCUs offer
effective solutions with evaluation and development kits supported by verified
code packages, debug and code-development tools, and validation suites.

microcontroller together in the same IC with a 3-phase gate
driver for N-channel power MOSFETs. This enables designers
to realize very precise field-oriented control of the electric
motor, 6-step sensorless or other advanced driving algorithms,
including the speed control loop. (Source: STMicrolectronics)
