Humanoid Robot - Project Update (August 2020)

In this video I share what's new in terms of reading sensor values and controlling actuators, I fail (several times) in having the shoulder working, and I'm designing a way for the robot to a bit more mobile.

looking good!

[@paulaslab]

James Bruton Thanks! :D

[@marianaurel]

:O when James Bruton himself comes to comment on your channel, you know you are doing it right!

[@coryshannon449]

It looks good. A bit of advice. If you coat/fill the 3d printed part in/with plaster and heat it up in the oven it helps strengthen the piece a lot! Also you can control synthetic muscles without pneumatics, instead using coiled fishing line and CNT or silver coatings/a wrap around the line. Look up "fishing line artificial muscle" and you should find stuff on it.

Outstanding project Thank you for sharing. Kids Robot academy Miami Florida USA

[@ChrisLocke1969]

Great project, Paula! I suggest simply putting 40lbs of weight at the lowest point of your chair when you need to stabilize it... that should hold it!

[@paulaslab]

Thank you Chris! And good suggestion. What I added now on the base is a lead battery that weighs 7.4 kg (16.3 lbs). It does feel less likely to fall back now :)

[@Badg0r]

This is so cool!!! Thank you for sharing this wonderful project.

[@coryshannon449]

Sorry to be commenting a second time so soon. And I think I have some advice for the arms. I rewatching parts of the video to get a better idea of what I was looking at. And it appears that you're robot's arms are not only too heavy, but aren't fixed to the joints in a way that reduces the stresses and forces on the parts. Going metal to plastic is a bit difficult to get just right but my previous comment does mention how to strengthen the plastic print. My advice here will be one that might be acceptable to your humanoid project. Have the joint be a ball and socket joint that you fix it to using a sleeve/net to prevent it from going off to the sides, and a few bits of elastic or rubber to give tension so the integrity remains. Then using a cord, wire, fishing line or whatever you have around use two actuators for the rotation of the humorous and to pull it down and two more for the longitudinal motion and one for pulling it up. This should put the motors and the bulk of the weight in the chest. I might email you a sketch as an example. If more of the weight is center of mass it will be easier to move around and balance. A human arm for an average 73kg person is typically 4kg, and a leg is 11kg-12kg. If the arms are too heavy then minor motions can throw it off balance. The most a human can swing around is 20% their weight, and that will throw them off if they don't counter balance with their body. Ideally the objects interacted with are under 10% of their body mass.

keep it up madam hard work make perfect

[@dodiddoneinc4003]

Wow. Looks good. I also tried making a robotic head. But I don't have so many things. Thanks for your video. For give me some courage. And God bless you.

[@MichaelDeeringMHC]

You could put hooks or eye bolts in the ceiling at places around the house where you typically work on the robot and have cord with some kind of quick release clasp to attach to the robot when you are working on it.

[@derubersoldatx]

poor guy the look in his face when he was about to hit the floor! thank God you grab him! Looking Great! love your work and dedication.

[@paulaslab]

Thank you! :)

[@daltonlightfoot6889]

You’re a robot looks great! Have you thought about decreasing the weight by switching out some of the components in the arms so that it is a cable pully system instead of a servo system? You might be able to pull off some multiplication of strength with a geared system with that. I am also looking forward to building something similar to yours, but I figure I need to get a 3-D printer and some basic Arduino/pi compatible parts.

[@wei1224hf]

So cool! You changed the Inmoov design a lot . Changed the arm from 3D plastic to aluminum , I did it too, I also changed the chest into aluminum. but I did't make it at last

[@HumanityAsCode]

Maybe use a harness to attach it to the ceiling just while you're working on it, but let it hang low enough so that it would be resting on that chair. That way if the chair falls, the robot is okay, and if you need to move it around you can just detach the harness from the connection to ceiling. Your project looks really cool

[@makelabsindia3092]

nice mam and we waiting more videos

[@marianaurel]

7:16 I would add an "EXTERMINATE....EXTERMINATE....EXTERMINATE" audio file to that face haha

[@robottinkeracademy]

add some weight to the base of the chair/wheels and it won't fall off. I am using a fairly wide pvc pipe on wheels which doesn't fall because it has a wide base and the robot is in the middle.

[@paulaslab]

Thanks for the suggestion! Yeah, I added a weight to the base (7.4 kg, i.e. 16.3 lbs) and it seems to be less likely to fall back now.

[@seok_vin]

I'm always watching your video,from "Philippines"♥️🙏

[@paulaslab]

Thank you so much! :)

[@seok_vin]

@@paulaslab You're welcome🥰🥰

[@Mnogarithm]

Wow this is beyond incredible. Hoping to be as good as you one day, great work!

[@Paul_Bearden]

I like your enthusiasm.

[@saravanakumar2765]

I love your project and your passion. Love from India.

[@daltonlightfoot6889]

You could have a four point tank tread on both sides with a swivel tension arm so that you can change the angle of the forward tread.

[@richardgilks2581]

I'm super impressed. I will be coming back to see further updates.

[@josshammer1886]

I just discovered your channel and I love it!

[@paulaslab]

Thank you! :D

[@sorooshb007]

Big progress this is awesome keep it up very interesting

[@paulaslab]

Thanks for your encouragement and support! :)

[@yoashuain1]

Try printing 100% infill pcs of smaller parts to get the weight down. Also using fewer servos that are more efficient will help alot. Pause on the torso disign , and work on the legs. Keep in mind if it can't stand on its own it will not be able to carry weight. Here's where it.gets tricky; think a 2 leg table. That's what we are and so your Android must be the same. I hope this helps, a little anyway. Keep up the good work. 🤖🤔

[@455329]

Great Job !! I simply love robots!! Greets from italy !!

[@jimkirk1701]

This might be too late as this video is from August, but you could use a car engine crane? Engine cranes usually fold up relatively small(ish) and can hoist and move an entire engine block about a workshop. It might be a much safer, more long-term solution, especially if one day you intend to test mobility, walking etc.

[@john2759]

Thanks, I love your videos. Cool 👍😎🎸

[@paulaslab]

Thank you! 🦾🤖🎸

[@madshroom]

I LOVE ROBOTS! I WANT TO SHOW THIS VIDEO TO YOUNGER ME I WOULD HAVE LOST MY MIND WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@johnathonwalty8915]

You might try printing nylon or ABS for parts that need more strength. Thanks for sharing. 😁

[@trstquint7114]

I like your videos and your work and progress on this robot!!

[@AltMarc]

Look out for an old office chair, remove the chair part and mount the torso. It won't fall over, bc it works for humans...

[@saravanakumar2765]

I am mechatronics student. Your video inspired me lots.

[@paulaslab]

BUILD ROBOT thank you, great to hear that! :)

[@SCWatches]

Brilliant. You probably have heard this already but now metal can be printed would that not be better for all the weight and action the shoulder has to deal with? New to this so forgive me if I have overstepped your enthusiastic and excellent work. Meant kindly.

[@jimp6576]

I think the chair is a wheel good idea. A patient lift would work. It is kind of like an engine hoist for removing the engine from a n automobile, but smaller. .

[@harjeetrawat3638]

It's so cool where are you from I am interested in robotics

[@CyberSyntek]

W00 more robot vids! Keep the build going!!!

[@JaviCarmona]

Wow!! Nice !! Can't wait to see the next video! 👍👍👍

[@yaroslavkiselev7310]

Nice job.(compliment)

[@danielkraus5662]

One way to keep the robot upright would be to put 2 hooks in the shoulders and have something similar to an engine crane.

[@Milky_GT]

it is beautiful what you can make at home

[@SuryanshInstrumental]

[@jimmymark8232]

thats awesome work，keep it up. like to see it walk soon.. You can do it..bravo for you lady🌹. 👍👍👍

[@Agamimg360]

okay so Ive herd you say you are an engener in 1 of your videos So stay with me on this 1. go to hardware store and buy a set of 6 heavy duty swivel style locking roller casters, a lazy susan with a weight limit of 550 lbs sorry don't know metric or what ever. also find a 30 gallon industrial grade plastic drum might have to get it online, Get 2" x 8' and 1+" x 8' heavy wall PVC pipes, heavy duty cotter pin maybe 2. When you get it all together build base assembly like this. add casters evenly around base of L/S then mount barrel on top of this, next take the finished height of you bot and add a couple inches to it and cut the pipes accordingly. put smaller pipe inside larger one clamp them together or use a screw to bind them for a couple minutes. drill holes in both pipes at regular intervals, { while you have them together check to see that the cotter pins will go all the way through and work to provide a temporary hold for later ) Put the pipes in 1 of the small holes in the top of the barrel. mount the bot to the upper pole some were at the neck. Fill barrel with water for weight and you should now be able to move it around at while . Keep the videos coming as my Grandson and I are also building our own humanoid bot and like to see what everybody else is doing to get new ideas. have you seen were 1 of the college labs has developed a synthetic skin that can give your humanoid bot a sense of touch. We are planning on using this on several layers of our multi layered skin. we also cheated a bit and are using a store bought precast plastic human skeleton, This will give us a lighter weight to start with and we can add more plastic to in fill the hollows if need be, If not we might run wiring through them ( except at joints were we will need to exit the bones to prevent pinching & there by shortening the life of the wires ) Any way I'll cut it off for now or I'll ramble all day . Thanx again your friends in the bot world.. P.S. have you seen Ricky Ma's build he used Scarlett Johanson as his body model. He calls it M-1 but every body else calls it Scarlett Lol....

[@abidemiadejumo5563]

This is splendid

[@arranciske7297]

looks amazing

[@studiovolantis6650]

Add a kick stand to the back of the chair so it doesn't flip back and maybe some wheel locks.

Cool. So Paula I recommend to visit the Miraikan Museum of Emerging science and innovation. The museum is located in Tokyo ashimo is currently being displayed in the mirikan museum. Ashimo is a amazing robot. I really hope you can see this robot one day

[@mohammedaasri2774]

Great

[@tomburns5231]

Perhaps put on/off locks on the wheels?

[@paulaslab]

Thanks Tom - yeah, actually one of the wheels (the one in front) can be locked, so that does help with keeping the entire chair/robot in one place while I'm working.

[@anuragalvino7630]

better try making the video with stable camera next time... literally wasnt able to figure what actually u were tryin to show or how does it work

What kind of engenering you study?

[@catserver8577]

Maybe try an office chair that has 5 wheels.

[@paulaslab]

Yeah, at least 4 wheels would be an improvement. I basically used things that I had around at the time, and after completing it, I realised... I kinda created my own office chair, only more restricted in motion and less comfortable 😂😂😂

[@catserver8577]

@@paulaslab Where I am, stores are not even allowed to sell office chairs without the five wheel set up, due to the instability.
