Hobby Motors For Robotics Stepper motors are ubiquitous in hobby robotics projects: If you make a robotics or automation project today, it is very likely you will use them. Almost all DIY projects from 3D printers and CNC mills, to various custom robots and automation solutions use them. However in industrial automation, brushless servomotors have taken over, and it's clear why: They don't lose steps, are much more powerful, efficient, and silent. Brushless motors are not unique to expensive industrial automation equipment.
In fact, you can get some very powerful and cheap motors at hobby shops. The electronics to drive these motors are also dirt cheap. So how come virtually no non-industrial automation systems use them? To be honest, I have no idea.
Seriously, a driver that allows this should clearly exist. But since it didn't, I decided to make one. And you are invited! This project is open source, both in hardware and software, and I warmly welcome anyone who wants to join. Oskar Weigl. Key specs. Controls two motors.
24V and 48V versions available. Peak current 100A per motor. Continuous current depends on cooling:. Encoder feedback for arbitrarily precise movements. Supports two braking modes:. Brake resistor. Regenerative braking.
Optional use of a battery means you can achieve very high peak power output with only a modest power supply. Open source:, Interfaces. USB - Custom protocol, open source. PC, RaspberryPi, etc. ROS node (coming soon). Step/direction - Existing motion controllers.
UART - ), mBed, etc. Servo PWM/PPM - RC Recievers, Arduino, etc. CAN - Synchronise multiple ODrives (coming soon). Some general purpose digital and analogue pins Protocols. Many types of command modes. Goto (position control with trajectory planning).
Position commands. Velocity command. Torque command.
Example: Let’s say you purchased the Unsync annual plan at $39, and after 4 months, you want to switch to the new Premium subscription. We will apply $26 credit toward the cost of the Premium plan. Don’t worry about doing math! It will be automatically calculated for you at the time of purchase.

If you wish to remain with your old subscription plan, you can. We are not retiring the old subscriptions or mandating a move to the new plan. However, if you do upgrade to the new plan, you can not revert back to your old subscription or any other subscription. To buy Premium for your group at once, go to activate the feature. You'll learn how you can create an Org and invite users with their email addresses. After inviting your team, you'll be able to upgrade the Org and pay for all of your users at once (one credit card, one transaction). If you have any questions or need help, please and we'll make sure you are successful buying for your group.

NOTE: Orgs will have other team-oriented features coming out, too. Group purchasing of Premium is the just the first available public feature. There's more coming soon!
