Robot Dog Part 2: Leg Redesign

[@googleyoutubechannel8554]

I can't believe a single person has gotten this far, def. the best robot build right now on YT, I don't think most people realize the amount of design / redesign / integration required to get a robot project with these conflicting simultaneous goals to a working state.

[@AaedMusa]

very true!

[@acect]

dude the editing on this video is actually slick though

[@HEMASimian]

I'm really enjoying your videos. I'm not an engineer, and don't know what you're talking about 90% of the time. But your editing and presentation makes it entertaining to watch nonetheless and am enjoying following this series

[@sebastian_abreu]

This is fully amazing man. Fantastic work. You will get the recognition really soon! I believe in you 🙏

[@ericeide6230]

just found your channel, really digging the humor mixed in to your videos! I just hit subscribe so keep that sweet sweet content coming!

[@EliSmith]

This is currently my favorite KZbin series, can't wait to see more great videos like this! Hopefully longer ones come too, I think a lot of people would be interested in more depth of how you solved these problems and not just the end results of days of work.

[@AaedMusa]

I appreciate the feedback. According to my KZbin analytics, on average, people only watch the first couple of minutes of my vids so I'm trying to cut down the video time. This might change in the future.

[@suomi35]

Same! This is genius.

[@johnrutkowski9005]

​@aaedmusa I feel like 10-15 minutes is my optimal watch time if I really like a channel, and maybe a little less if it's someone new to me and up to 20 minutes if it's cool I'd assume once things get rolling for you your average watch time will increase as well. Upload frequency also probably has an effect, there are channels that only put one hour long video out a year that do great, so if you only do one a month or so I don't see why 6-12 minutes would be too much. Personally I would have watched the whole thing if you had combined the pt1 and pt2 videos, but it is nice to have chapters to it if you don't want to commit the time.

[@AaedMusa]

@@johnrutkowski9005 interesting insights. I definitely feel the same way about watch time when it comes to the content that I digest. The only reason I’ve divided this project into chapters is because it’s such a long project. I try to put out a video once a month or so which means that I hadn’t done or thought about part 2 when I finished the part 1 content. I also try to only put relative meaningful info in my vids. This video could have been over 10 mins if I talked about my entire process, but my entire process isn’t relevant to the audience.

[@jacquesandre2565]

@@AaedMusa Your entire process might be more relevant than you think. If your public is people who want some entertainment watching a robot dog jumping, you're right. But if your public is people who also are interested in making robotic projects (even if not walking dogs) then your process is very relevant because what you're struggling with is probably also what they're struggling with...

[@havoklad7616]

I'd love to see where this goes, can't wait for part 3!

[@oban3773]

Awesome video. Poor Plank! HOW COULD YOU?! Love the editing and this project. Cant wait for more.

[@victorsaisse1340]

can’t wait for the full robot! awesome content mate, you inspired me to finally buy my 3d printer after years of just watching videos lol

[@ChrisLocke1969]

great progress, my friend! Keep us updated, please! I know it can be a pain making videos, but we appreciate it lots!

[@z0mb13h0rd3]

I’ll can’t wait to see your next video, I am in awe.

[@julianeulderink6172]

this is dope! can't wait till part 3.

[@Animator-s5t]

Unbelievable stuff. Can’t wait for your next videos 😊

[@kavorka8855]

you’re encouraging me to use my apple pencil! you’re an amazing engineer!

[@AaedMusa]

I love it, it’s honestly a great tool.

[@kavorka8855]

@@AaedMusa I just attached it to an ipad 5, it's zero battery percentage! Thanks to you, I might begin to use it. I think the way you design and calculate with it is just awesome!

[@TotalTimoTime]

Some small advice from one mech eng student to another: 1) dont use even numbers of teeth on your gears. Gear pairings should be co-prime to another, especially on soft gears like ones made from pla. Go ask your mechanical design textbook as to why. 2) dont use angled gearings when straight will do. Angled increases contact area between teeth which means your gears will wear out faster. Not a problem on case hardenend steel. Def an issue on pla. 3) belts arent great for transferring torque and since the one place you used them is the one that needs it most, consider using a beam or leaver connection between the wheels.

[@ChillGuy511]

Cool work!

[@RoccosStuff]

This is so cool. You must spend a lot of money on bearings lol

[@lint2023]

Reverse kinematics. I studied kinematics. I must have dozed off during the reverse kinematics module! Cheers.

[@unusualfabrication9937]

Incredible

[@Adam-oq2lq]

I really like video editing! Great project!

[@sebe4199]

Holy moly youre an engineer

[@clonkex]

"PIXAR" lmao, didn't see that coming

[@erikringwalters]

Awesome 😎

[@redles4212]

This is quickly becoming one of my favorite series, best of luck to you my guy. (also do you have a discord server by chance?)

[@AaedMusa]

Thanks! No I don't just KZbin.

[@shad303]

keep it up 👍

[@Ryan_Sauer]

Love your videos!

[@emillykke]

You are a legend. Keep up the good work!!

[@JC-Robotics]

I love following this project! I am about to order my first 3d printer in hopes of starting robotic engineering projects like this. Can I ask what program you were using to write your equations on your tablet please? Keep up the amazing work!

[@AaedMusa]

Microsoft OneNote

[@stefanguiton]

Excellent

[@amccfpv]

Very nice videos

[@ad9218]

Nice!

[@xgeneralpotatoes4941]

How did you calibrate the BLDC motor with the Odrive S1 for your actuator? Mine keeps saying Pole pair mismatch on the odrive GUI even though I put in 20 pole pairs.

[@AaedMusa]

I would refer to the Odrive documentation or ask on their discord server.

[@ewenblack4174]

👍🏾

[@diywithadvait9050]

nice

[@odonotso3941]

This, is Elon Musk Ps: honesty as a designer I'm very jalous of people's who are able to model AND code things at the same time to make actually stuff work, wish you luck and waiting for your next videos of this 👍

[@QuanrumPresence]

@aaedmusa I can help you port the CAN bus library to Arduino, if you still would like help with that

[@MarkTow]

Pixar 💀

[@adityavinayak7357]

Please continue this series It's the best I have seen till now

[@JoshGladstone]

KZbin algorithm sent me. Nice work! Subscribed!

[@marvintraxel6955]

Can you add some springs as gravity compensation? Maybe 3-5kg so the weight of the leg is compensated for

[@Emeth-d1c]

I badly really want to be a mechanical enginer!!!!!!!.

[@christophermacier]

Sub'd!

[@klausnielsen1537]

Excellent video. You are really pushing forward. I can not even imagine how much work went in to the redesign! 👍 Awesome!

[@johnrutkowski9005]

I've watched another channel similar to this one go from where you are now to hundreds of thousands of subscribers, and I can easily tell that is where you are heading. The combination of skills, knowledge, and video format is perfect. A year from now I expect you'll have over 100k subs and be doing this full time. Good stuff man.

[@AaedMusa]

Appreciate it! I’m probably never going to go full time since I’m in school, but I would definitely love more subs.

[@xenontesla122]

I'm really impressed with your work!

[@irkedoff]

It's great to see another video of your progress. Thanks for sharing.

[@matatisan]

Great videos!

[@systemG3000]

That was awesome, I just hope you can figure out how to get position information natively

[@uldurulenemoji]

keep it up nice content

[@birdgirl0073]

👏👏👏

[@Dagor]

Redesign looking great!

[@erk_viewer]

Very cool project! As a noob in robotics id like to know what will be better for a robot arm if ill’ use servo or stepper? The arm has to be small and be not fast. Ty for the response and keep it up with ur awesome vids 🦾❤

[@noahboursier]

for a low cost project a stepper is probably the better choice for you

[@RoohollaKhorrambakht]

Is there a reason for not using your cycloidal transmission you designed 2 years ago?

[@AaedMusa]

It didn't have the gear ratio that I wanted, didn't work well, was too heavy, and used a completely different motor.

[@xarlixe7565]

Amazing serie, and the level of editing is impressive ! Very impressive project : )

[@whatthefunction9140]

How does that british guy iterate so quickly

[@bruceboggemes9724]

[@raudy6-]

Nice vid! If you don’t mind, what brand/color of pla is that cyan? I love it a lot

[@AaedMusa]

Bahama blue PLA. Sold by Zyltech

@@AaedMusa ty

Add springs to counteract expected robot mass in neutral position. You can add much more force that way.

[@AaedMusa]

The FOC motor controllers already allow me to change leg stiffness in the software. Springs would just add weight and make the motion less compliant/dynamic.

@@AaedMusa The leg should have springs that extend it passively (help motors to lift robot weight). This way you can add more strength to the leg with little more weight and really cheap.

[@L3X369]

Quite awesome progress! I wish I had the guts to make something like this. Your dogo will be quite amazing! PS: Who the f would thumb down a video like this?

[@billstrahan4791]

Fantastic work! And awesome that you’re sharing it.
