$300 120Nm robotic actuator from aliexpress - ROBSTRIDE04
Просмотров 32 тыс.Месяц назад
Setup with Python: ruclips.net/video/-IVK60lWsBg/видео.html I was browsing Aliexpress, as one does, and found a robotic actuator that advertised a peak torque of 120Nm. I checked out the spec sheet and it is rated to do 120Nm for 10s but its nominal torque rating is 40Nm. I’ve been trying to design my own actuator and this one being only about $260 ($300 after shipping/tax), blew my mind. I did...
Arcane Pixel Staff Test (DIY Handheld Persistence of Vision Display)
Просмотров 154Месяц назад
I wanted to build a persistence of vision display for my Renaissance Fair wizard cosplay with the intention to display arcane sigils and designs, though it should be able to display anything. This was the first test, it is displaying a square (although it appears very pixelated). Inspired from the normally static fan-like POV displays, this display is designed to fold from a walking staff to a ...

Took me a while to figure out what was going on lmao, awesome thingamabob!
Oh my God, I fucking love you. This is exactly what I've been racking my head trying to figure out for the last month, exactly with the brushless motor, simple foc, as5600, 3D printed design, deciding to not use roller pins any more, the fucking black colour scheme, etc. I love you man
P.i.m.p
I have the O3 and just keep getting this error: 1 [2024/11/05 21:04:18] Connect overtime, try baud rate: 9600 2 [2024/11/05 21:04:19] <ERROR> USB-CAN module configuration failed, please check physical device! I have tried swapping can high and low wires, unplugging usbc etc. I was able to get it connected once but now it wont connect at all, any ideas?
I have exactly the same problem! Does anyone have a solution? I tried contacting Robstride for support, no reply yet.
Yeah you have to change the baud rate I fixed it
@@kaydenk where did you change the baud rate? In windows settings or somewhere else? What did you set it to?
120 Nm, in kgf/cm please
Did you make these AR glasses? Or buy them?
these are a pair of Xreal Air’s, seems they go for around $200 now
Hi, I do have questions about this actuator. Does the encoder on it work well?
Question : Do you think this could output 30Nm for ballscrews?
What would be the minimum movement possible? Like the step angle for stepper motor
I just got 2 in the mail, the manual isn't really too helpful it mentions 14 bit (absolute value of a single lap) but it also mentions it has a built in 9:1 reduction
Thanks for the files... I love your design!!! I tried it myself but would love to compare my mistakes to your design to learn from it
can you share the lazer cut files for me to try?
wonderful walk through the steps my friend. The only thing i don't understand is why go through virtual machine just to send serial messages to a com port. I just ordered the same motor. It actually went 42 dollars up in price :) .... propably they realized that they made it famous up to a point with the cheap price and now slowly they will follow the ordinal prices. I am looking forward to see your next videos and more demos on running this motor.
It’s not necessary to use WSL, it’s just my preference as I need a windows machine for SolidWorks but prefer my software development environment to be Linux, and this way I can have both, and thank you! stay tuned!
@@kindaovermyhead i envy your skill to use linux :)
Would this set up be relatively similar for the O3?
it should be relatively similar but I do not have one in hand yet to confirm
Simple fact If it weighs a lot it cannot be good for robotics im making an actuator that will be super light weight and strong
keep it up 🥰
Se puede igualar la velocidad de respuesta?
The program is really bad to be honest, i’m surprised it’s running at this speed. it can be improved- it’s xrealsdk->unity->flask server->python->serial library for the servos
This is just a CAN bus geared servo. Nothing special here... The gain looks a bit low and its position holding looks really bad (by CNC machine servo standards anyway) so you need to adjust the PID parameters.
yeah the pid tuning is my own and not great yet, i’ll find out soon if it’s special or too good to be true
Actually, can you do me a favor and program that thing to wave around 20lbs at full speed?
will be doing that dw
I see they have a ROBSTRIDE03 as well .. this one looks very interesting too!
it does, i hope to try it!
so did you make any more checks? does the actuator actually handle 120Nm or near this value? What commands are supported throught the can bus?
the commands are available in the docs on their site, and i’ll find out soon if it’s capable but gotta improve my setup first cause..safety :)
what power supply did you use? also how did you make a joint to both sides of the motor? I am impressed with the video
i’m using a 24V 15A power supply from an old ender 3, and it’s a bearing on the other side in the 3D printed part
Seems like a great motor, but $300 is awfully expensive, given you'd need like 4 of them for a humanoid, if not more. What do you plan to use this for?
i mean you’d need at least 5

dang that is nice
Woah, that's impressive!
Looking forward to more testing.
Good but not great. Snapping jump cut needs work.
idk at what voltage you ran it but of course you cant hold 120Nm or even 12Nm with that 2 cm leverage... you are trying to counter equivalent to over 1000 pounds with your fingers there.. Itd probably be impossible for you to do even with a normal sized wrench(30cm). Cool motor tho. I would love to see the gearing and more of the inside. I wonder if its just one set of planetaries or multiple and what kind of machining and material quality its for that price. Sometimes chinazon really delivers
$300 product and the give you only 10cm of cable like come on, spend 50c more and give a meter...
W ENDING
So this is driven by CAN signals. The "controller" is built 8into the drive? You are just supplying Voltage and CAN?
yes just supplying power and a CAN signal via their own CAN to USB adapter
i am the landlord , it will be 4000$ to change those breaked tiles 😅😅
"breaked", Uneducated moron like you can't be the owner of any house.
120Nm because of gear reduction
yes, it advertises a planetary gear reduction
Dozen of these for robodog 🤩
So did it manage 120 Nm or not? what was that ending lmao
i will be finding out soon with a stronger testing setup
120 Nm... I know! Why not make a hub out of flimsy 3D printed plastic goop 😑
just gotta use stronger goop
Ham and cheese outro is interesting :D
The software looks like the Xiaomi cyberdog Motor Software...be careful 🤞
why did you say to be carefull? what is wrong with xiaomi software?
Market Basket #22 in Tewksbury?! How was that cheese?
Reminds me of the ones Unitree robotics use in their heavier quadrupeds , i recall that the heavier quadrupeds do have motors that achieve 120nm (or more) , thought these motors cost 1500 dollars without taxes or shipping fees
That looks so cool. That sensor has a lot of use.
May know this already: * Rated current on actuator is peak phase current (which is not related to supply current unless at peak rated speed of motor at 48V, which is kinda unachievable) * Therefore your supply should handle peak torque (even at 30V) at low velocity, so just dial down those gains. * Your supply may have cut out due to an over voltage event due to BEMF generation during backdriving of the actuator (not an issue so mych with battery powered) * To handle these BEMF event your need a "regen shunt" (check o-drive for that) * The BEMF exhiibits itself on the voltage bus by exceeding the voltage setpoint of the supply. * You'll note when the weight is being lowered, due to the potential energy of the lifted mass, the current in the supply should drop ~0amps at times. * the above is predominantly just a warning so not to blow the control board or other devices connected to the voltage bus if they're not able to handle the transients and over voltage events. * testing at 24v, and getting a baseline of behaviour is safer, you have a much higher chance of damaging the controller when running at max operating voltage and then having a large Regen event (backdrive)
this is seriously very helpful, thank you!
@@kindaovermyhead All good, keep at the testing and I'll be folliowing the progress, you're doing good. Shout out if you hit any hurdles, happy to give direction. Breaking things is all part of the process.
@ZedDead-n3s zeds dead baby, pulp fiction and the music big fan
@@ZedDead-n3s Sir, i face the same problem ... when my motor accelerates with some weight on it, and i want it to stop in a specifiv position , it shuts down when it is supposed to stop. I was thinking that there is reverse voltage that with the one added from the one that comes into the motor results in low voltage so the motor shuts down. In the odrive they give you a breaking resistor. But in my motor i don't see how i can implement it. Is there another way to avoid this problem? what is the regen shunt that you mentioned above?

u print that at 0.24 layer? what filament u use?
yeah 0.24 and generic pla for a temporary mount
No statement anywhere about backlash...
knew I forgot something! Its backlash isn’t advertised, it feels near zero, but I didn’t have my dial indicator on me to test this time around
@@kindaovermyheadfor lots of applications this is more important than pure torque. It is a planetary gearbox so probably not that good I'm afraid...
This actuator is meant for dynamic applications (e.g. robot dogs) where backlash is not as critical as transparency (i.e. reflected inertia/efficiency) and torque
does that continuously roatate?
yes
@@kindaovermyhead perfect. Would be great to drive a small capstan.
@@docdailey sure, a small capstan lol
@@AnnaVannieuwenhuyse exactly what I need. was going to repurpose hoverboard motors... but i need tight control of position. Multiple capstains working in concert.
probably interesting but couldn't watch. video made me sick
