3D Printed Robotic Actuator

Great work!

[@AaedMusa]

Thanks

[@tcratius1748]

For the noise, add some plastics gel lubricant, silicon I think, will reduce the noise a little. Otherwise nice work! :)

[@AaedMusa]

good idea, I haven't tried that.

[@kylewatson952]

Keep up the good work man love this

[@AaedMusa]

Thanks

[@seanbosse]

Hi, aside from adding to the encoder, how did you convert the Riorand speed controller from velocity control to position control? Awesome job, btw! Thank you for sharing.

[@vanlife4256]

Awesome job! Great content! Thank you for sharing and contributing to the Maker’s community! Are you using the Imperial (or Freedom lol) units for designing your projects?

[@AaedMusa]

I use both unit systems. I usually use imperial units for bigger dimensions such as the diameter of the gearbox. I use metric units for clearances and tolerances.

Nice work ...

[@antonwinter630]

looking forward to seeing the quadroped leg moving!.

[@AaedMusa]

Hopefully soon I’m working on a new, better actuator

[@DWIRobo]

cool job

[@AaedMusa]

Thanks

Hey man! I'm using the exact same motor for my quadruped build. I think you're going to have a hard time with the stability of the bot with such a high reduction ratio. You generally want a very backdrivable box to have natural compliance.

[@AaedMusa]

Yea I have realized that now. I'm currently working on a new cycloidal gear drive with a 28:1 reduction so that backdrivability isn't an issue. Love your content by the way and thanks for the tip!

[@emmittcolten38]

instablaster...

[@lukefischer7880]

do you think 6:1 is too little reduction

[@Dagor]

@@lukefischer7880 I've been using the same brushless as the video and I have 9:1 reduction. I wish I had gone with 1:10 or 1:11

[@wei1224hf]

哇！厉害厉害！

[@pedrokdc]

Great Work!!

[@AaedMusa]

Thanks

[@3dprintwiz378]

Please do an actual torque test on the actuator. Thanks.

[@AaedMusa]

Already did kzbin.info/www/bejne/sKXNi3eml7uknJo

[@Build_the_Future]

I love it, I'm glad you're using an encoder and brushless motors. I'm building a biped walking robot on my channel I have a lot of problems to work out, but it's only my first version. Check it out if you're interested. I look forward to your next video.

[@AaedMusa]

Thanks! Currently working on a new planetary gear box and I make it a bit more compact. Your bipedal robot look awesome. Your definitely on the road towards making the next Atlas! What kind of bldc motors are you using by the way? And have you considered using a QDD actuators?

[@Build_the_Future]

@@AaedMusa It's my first attempt to understand what I didn't know and test my software in the real world my next version will have better actuators, but I don't know what yet. I'm using 192kv 50v 80amp 4000w (That's more power than the timing belts can handle)

[@AaedMusa]

@@Build_the_Future nice, definitely check out MIT’s Hermes bipedal robot for some more inspiration. I look forward to viewing your future versions and any of your other projects!

[@kingmasterlord]

tell us about it SoCal Norm Macdonald

[@REDPHOENIXVR]

what the toque in Kg ??

[@marobugvanyen8737]

Do u have link for buy drive motor ?

[@einzeln00]

Assuming 3 stages of 5x reduction planetary gear sets, and very small module of teeth, the final efficiency will not be ideal even for a 3D printed gearbox. kzbin.info/www/bejne/sGPVf4Glba6po9k is a differential type of planetary reduction, which derived from flex drive, and same principle from "gear down for what" type, maybe you will be interested and bring you some idea.

[@AaedMusa]

Interesting, I've played around with a split ring gearbox before but I just couldn't get it it be backdrivable. May be worth looking into again.
