Robot Dog Part 2: Leg Redesign
ฝัง
- เผยแพร่เมื่อ 17 มิ.ย. 2024
- In part 2 of building a robot dog, I'll be redesigning the leg, switching motor control from UART to CAN bus, continuing to program step sequences, and making the leg jump! Subscribe for part 3 where I'll be designing and building the full robot.

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.
very true!
dude the editing on this video is actually slick though
This is currently my favorite TH-cam 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.
I appreciate the feedback. According to my TH-cam 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.
Same! This is genius.
@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.
@@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.
@@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...
Please continue this series
It's the best I have seen till now
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
This is fully amazing man. Fantastic work. You will get the recognition really soon! I believe in you 🙏
Excellent video. You are really pushing forward. I can not even imagine how much work went in to the redesign! 👍 Awesome!
TH-cam algorithm sent me. Nice work! Subscribed!
just found your channel, really digging the humor mixed in to your videos! I just hit subscribe so keep that sweet sweet content coming!
I'd love to see where this goes, can't wait for part 3!
I’ll can’t wait to see your next video, I am in awe.
this is dope! can't wait till part 3.
I'm really impressed with your work!
Redesign looking great!
Unbelievable stuff. Can’t wait for your next videos 😊
Awesome video. Poor Plank! HOW COULD YOU?! Love the editing and this project. Cant wait for more.
great progress, my friend! Keep us updated, please! I know it can be a pain making videos, but we appreciate it lots!
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
Amazing serie, and the level of editing is impressive ! Very impressive project : )
It's great to see another video of your progress. Thanks for sharing.
Cool work!
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.
Appreciate it! I’m probably never going to go full time since I’m in school, but I would definitely love more subs.
You are a legend. Keep up the good work!!
Love your videos!
Great videos!
Very nice Video!
Love the one legged dog!
you’re encouraging me to use my apple pencil! you’re an amazing engineer!
I love it, it’s honestly a great tool.
@@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!
Holy moly youre an engineer
Incredible
Excellent
keep it up 👍
I really like video editing! Great project!
Very nice videos
keep it up nice content
That was awesome, I just hope you can figure out how to get position information natively
Awesome 😎
Nice!
Fantastic work! And awesome that you’re sharing it.
This is so cool. You must spend a lot of money on bearings lol
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?)
Thanks! No I don't just TH-cam.
You amazing 🤩
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.
Reverse kinematics. I studied kinematics. I must have dozed off during the reverse kinematics module! Cheers.
Can you add some springs as gravity compensation? Maybe 3-5kg so the weight of the leg is compensated for
Youre crazy dude
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!
Microsoft OneNote
you should build in some kinetic energy storage device you can wind up and launch the robot into space with much more power than the motors can produce
nice
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 🦾❤
for a low cost project a stepper is probably the better choice for you
Add springs to counteract expected robot mass in neutral position. You can add much more force that way.
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.
Great job man, 🎉🎉🎉
"PIXAR" lmao, didn't see that coming
Nice vid! If you don’t mind, what brand/color of pla is that cyan? I love it a lot
Bahama blue PLA. Sold by Zyltech
@@AaedMusa ty
aweeeesome now that leg needs a brain! any plans? Torch, keras? , Jax,Flax? RL?
Teensy 4.1
👏👏👏
Sub'd!
👍🏾
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.
I would refer to the Odrive documentation or ask on their discord server.
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 👍
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?
Is there a reason for not using your cycloidal transmission you designed 2 years ago?
It didn't have the gear ratio that I wanted, didn't work well, was too heavy, and used a completely different motor.
How does that british guy iterate so quickly
I badly really want to be a mechanical enginer!!!!!!!.
@aaedmusa I can help you port the CAN bus library to Arduino, if you still would like help with that
I would love to scale this up BUT the programming is way over my head
