High performance open source server ODrive

ODrive is a high-performance FOC servo driver based on STM32. It can drive two brushless motors at the same time. In the early days, it was widely used in the design of 3D printers or homemade CNC lathe electrical systems. The well-known geek James Bruton used it as most of his own To make the core unit of the robot servo drive, Stanford's previous open source 8-degree-of-freedom quadruped robot Doggo also used Odrive as the core driver.

The author also wrote a set of configuration and debugging tools based on Python, which are used to set drive parameters, view drive feedback, etc. At the same time, the hardware part is also open source. You can ship the PCB yourself or buy it on Taobao. For about 600, you can buy a high-performance servo motor that can drive two servo motors at the same time and have a single current of more than 60A. You must know that Elmo's drive, ODrive with this performance, costs 10,000 yuan. So ODrive is the best choice for making robots.
