https://hackaday.io/project/179234-moteus-brushless-controller https://hackaday.io/project/28512-bldc-motor-driver-for-robotics was trying to build a robot but did not like servos, I wanted smooth direct drive. This controller acts as a smart servo, it receives commands via RS-485, writes back angular position and can apply constant torque in when stalled or moving very slowly. https://hackaday.io/project/159404-opentorque-actuator OpenTorque is an open-source implementation of the quasi-direct-drive actuation scheme pioneered by the MIT Biomimetics lab. The basic premise is this: use the largest possible motor with the smallest possible gear reduction. This results in an actuator that is robust, highly backdrivable, and capable of proprioceptive force sensing and open-loop impedance control. These are all ideal attributes for building legged robots. Used by https://hackaday.io/project/160882-blackbird-bipedal-robot and A sub $500 open source walking robot that can be used to test out control algorithms and simulation fidelity using semi-direct drive torque control.All design files are available here: https://github.com/DarrenLevine/TipTap. BLDC motor controller (DizzyServo from dizzy.ai) manufacturing details: https://github.com/DarrenLevine/DirectServo from https://www.dizzy.ai/documentation/motor-driver/ DirectServo is a microcontroller that drives BLDC motors as servo. It was tested on gimbal motors but can technically drive any motor that has magnet attached to its rotor.I initially intended it as a servo for humanoid robot but it turned out to not be strong enough (just). However the design is successful and can be used for less demanding applications. It was designed to apply constant torque in stall situation or when spinning slowly. No matter what resistance the rotor experiences, controller will measure its electric angular position and apply SIN PWM at +-90 degrees.

Motor control
https://github.com/ytai/ioio/wiki/Motor-control The Motor Control API, which was added to the IOIO library in version 5.00 makes it easy to control a large variety of such setups with very high accuracy and speed. What it does essentially is generate digital waveforms of various kinds, which correspond to different kinds of actuators.

filter
Remove the low pass filter on the ESC, allowing higher P(proportional) control values, which stabilizes the quad in wind gusts.
