I’ve had the qdd100 beta kits available for some time up at mjbots.com, I’m excited to announce that I’ve completed a production run of the beta qdd100’s and they are now available standalone as well.
I look forward to seeing what everyone creates!
Developing the moteus brushless servo controller has been a very long journey, and while it isn’t over yet I have a reached a significant milestone. The first batch of production moteus controllers are now available for general purchase at mjbots.com and shipment worldwide for $119 USD each!
I’ll repeat some of the specifications here:
Simultaneously, I’ve got development kits available that give you everything you need to start developing software for the moteus controller out of the box: moteus r4.3 developer kit
I’ve received my first production run of the fdcanusb CAN-FD USB adapters and they are up for sale at mjbots.com!
While this is necessary for interacting with the moteus controller, it is also a fine general purpose CAN-FD adapter. At the moment, the USB interface is a platform independent line based serial one (Windows, Linux, MacOS). It doesn’t yet interoperate with SocketCAN on linux, but hopefully that will be resolved in the not too distant future.
In my quest to create a more dynamic quadruped, I’ve started accumulating a lot of parts from bulk buys that could be reasonably useful to other hobbyists and experimenters. To maybe make life easier for everyone, I’ve started up what may be the worlds ugliest online shop where you can buy some of these components. For now, I have some bearings and custom gears that are useful when building servos for dynamic robots.
moteus is an open source brushless servo actuator designed for use in highly dynamic robots. It consists of PCB designs, software, and mechanical designs necessary to construct powerful brushless servos, and link them together into legged robots. Today I’ve published the full source and designs for all of this work on github under an Apache 2.0 License - https://github.com/mjbots/moteus

These are the software and designs I have been developing in order to replace the actuators on Super Mega Microbot (which will probably get a new name shortly as well). It isn’t done, but at least the controller is working well enough now that I have a pre-production verification run of ~30 controllers in flight. Even still, I expect that further evolution, both on the controller board and in the mechanical systems is inevitable.
