Very cool! Impressive specs. I love that we all use XT30 connectors! The only thing it misses is an Ethernet connection. Absolutely phenomenal that it's all open source!

@awesjosh 2 ай бұрын

Yeah, standard ethernet connectors are very large for many of the applications moteus is used in, besides that since the micro mjbots has standardized on doesn't have an ethernet controller it would require either an external controller or a switch to a different micro. ethersweep is looking cool, keep up the good work! If you ever need performance beyond what steppers can provide, moteus is there for you!

Nice work! For my needs I would like to see a little more voltage, 60v or more and higher amps. I would be willing to pay more if it had that capability.

@awesjosh 2 ай бұрын

You might be interested in something like SOLO: www.solomotorcontrollers.com/shop/ However, you will find very few inexpensive drives that go all the way up to 60V.

The small hoverboard robot looks amazing! Do you plan on releasing the buildfiles for it? The moteus-c1 lookes really nice for this application.

Yes, eventually! Thanks!

Stupid question here, but why couldn't you just add more MOSFETs in parallel to be able to control more current or in series to control more voltage?

@awesjosh 2 ай бұрын

You can't really put FETs in series, or at least not in a practical implementation. Putting FETs in parallel is common, but to a point you can also just use bigger ones. For instance, the moteus-n1 has about 5x the peak current output capability of the moteus-c1, and has a higher voltage rating (54V vs 51V) to boot.

in the example at the end 1.5 was a fault because the range was set to -1 to 1. however after you power down completely, will it still remember that it was at fault? while its on its recording how much the position has changed and knows the position went beyon the bounds. but will it still be at fault after cycling the power?

@awesjosh Ай бұрын

Faults are cleared by sending a stop command, in tview that would be: d stop Power cycling will also work, but with the devkit you will need to remove power from the PSU for some time before it discharges completely. Also, don't hesitate to join and ask questions in the mjbots Discord, it is a lot easier to get support there than in youtube comments! discord.gg/W4hUpBb

Balancing robot is amazing! What algorithm for balance control do you use? Do you have other videos or information about this robot?

@awesjosh 2 ай бұрын

Thanks! Not much other info or video yet, but @mjbotsrs on x/twitter does have a video with a few new cuts. The control is just an inner pitch PID loop using the pi3hat ARS, and then an outer PID loop that controls velocity through selecting pitch.

Do you offer brushless out runner drivers for smaller diameter pancake motors? Like a 1803 motor? Would love to drive small robot parts (like in animatronics) in place of noisy traditional servos.

@awesjosh 2 ай бұрын

The smallest driver mjbots offers currently is this moteus-c1, which is 38mm x 38mm.

In the balancing robot, are you using C++ or Python?

@awesjosh 2 ай бұрын

C++, although it would likely be just as possible with python.

I almost bought a bunch of them for my company, but It has no Rust bindings. 😑

Heh, I guess that will severely limit your choices!

@@awesjosh Absolutely. We are memory safety first. Security is our highest priority. We just ended up designing our own Rust based ESC!

@awesjosh 2 ай бұрын

Yep, it is the way of things! In any event, bindings are not really a big effort and I would expect writing the rust code to generate and parse frames for the things you are using would not be a significant fraction of your integration effort.
