The moteus brushless controller turns a hobby brushless motor into a high performance servo actuator.  It integrates the necessary drive electronics, a high performance 32 bit microcontroller, an absolute magnetic encoder, and a high-speed data interface in a compact package.  Power and data are daisy chained for integration into multiple servo systems.

They can be used to build dynamic robots like the mjbots quad A1 (inspired by the backflip capable MIT mini-cheetah).
