6:51 the large gear warping under the load. This isn’t what I usually watch on YT, but the thumbnail got me. It’s pretty amazing what a small brushed motor is capable of, especially when it’s connected to some bit of plastic.
I think this is QUITE impressive, i must say, Lego wasn't ever meant for this kind of lifting but youre solving problems like an engineer should, replacing string with nylon rated at 65kg, splitting the load over two separate points, here i thought i was smart putting together a 3 speed sequential gearbox to solve my power issues in an rc convered lego technic model, i could learn a lot from this. If i put something like this together for my rc car it would be awesome as a single gear system pushing 12kg of force out of a regular medium motor! Hmmmmmmmmm
Rens Basically a 3 speed transmission, like in a manual transmission vehicle (most are 5 or 6, semi trucks use 15, 18 or more). RC means Radio Control.
I particularly like the fact that your videos are devoid of distracting music. I can listen to my podcasts and still watch your videos without loosing anything. Thank you!
Rather think more than rest. Majority of people are resting, not thinking any more too much and are getting dumber... Where are brilliant minds like were Tesla, Maxwell, Einstein, Schroedinger? There are already almost 8,5 billion people and coal, gas and oil are still the most important energetic sources... People did not even return to the Moon since the early 70s... today this mission rather seems a mission impossible! And landing on Mars seems like a thought from a scientist from the early 50's - non reachable!
Typically the rated strength of something is about half of the test strength, which is below the failure point. Because a rope lifting a load off the ground at a 60 degree angle to vertical has tension up to twice the weight of the load plus the weight of the line and associated hardware. If you're making something in the 25kg rated load range, you expect a bunch of amateurs to try crazy stuff that doesn't follow any kind of best practice; if you're int the range of hundreds or thousands of kg, you expect a bunch of professionals lifting expensive things over expensive things; either way, a safety margin of 2 is reasonable.
This is absolutely astounding, I teach with Lego Ev3 for a living and I've seen those exact problems you've encountered where the axles sheer in half, the gears bend side to side and disengage. It's crazy that little plastic parts can lift 120 lbs. I'm going to have to show this video during one of my lessons (and of course explain how many kilograms are equal to how many lbs). My students after seeing this shouldn't ever had an issue again with lifting weights for their challenges
Thank you so much. This is the best compliment I've had so far. Hope your students find the video useful. I've always thought the fastest way to learn is from mistakes, preferably someone else's. :)
Brick Experiment Channel if I get a chance I'll have to send you a video of their robots in action at the end of the week with these new gear ratios fresh in their minds. They don't need to lift 120 lbs, but still their robots will be climbing
Maybe you should focus less on weight conversion and focus more on the principle of reducing pressure by adding more load bearing points? How come you’ve skipped this so far? (While problem solved by this have apparently been common)
salmjak on his channel he had an entire video showing the usage of pulleys in the system to reduce stress exerted on the motor and thus adding more load bearing points. The issue with Lego is that it is plastic. The test was really more about what the little Lego motor is capable of on its own with the proper gear ratios. For more of a load bearing and building techniques for gears that be a whole separate topic. The main points there would be utilizing the technic beams/liftarms to distribute forces across a larger area, using axles through sections instead of the axle pins, then using other gears or dual redundancy so the gears do not slip. (Ex: there are two different models of the Lego 8 tooth gear, one has just ridges in the middle and little tube ends that can slide into a technical lift arm and disengage under pressure (link: www.bricklink.com/v2/catalog/catalogitem.page?P=3647#T=C) whereas the 2nd type has teeth in the middle and lower ones on the sides and will not slide back and forth on an axle if sandwiched between two liftarms. (Link: www.bricklink.com/v2/catalog/catalogitem.page?P=10928#T=C) All that being said someone could make an hour long video on proper gear techniques and tips. Like there's so many little subtle things that will make or break a gear train
This is fascinating and truly is great engineering. I just cannot understand how such simple thing like adding more gear and making it more complex can create such strength
LOL.... dang son, that was violent, I must subscribe after that... had me on the edge of my seat.... I may have to dig out some of the Aluminum parts that I made back in the day, of course a full selection of gears, pulleys, axle shafts, and the fun ones to make, the U-joints, and send'em off to your P.O. Box to see how much abuse they can take to the point of failure. That was fun to watch...
Dru Bradley why do you think aluminum has godlike strength I could bend aluminum with my fingers so can anyone else I would recommend something other than aluminum.
Always knew Lego was good for teaching kids about engineering, load, stress and weakness, gearing ratios plus the excitement of catastrophic failure (on a Lego scale). This should get some kids off the computers and work things out practically. Well done.
I did build stuff like that to pull the early 2000s Lego train up from the floor to my desk. That stuff really is durable when done right and that's really fun. (It was 4 m length and 75 cm up, which is a lot for Lego, the train itself couldn't do it, so I built it some help.)
You get the feeling that around the 4:00 mark, he was kinda getting pissed off with all of his pieces breaking or snapping or being constructed or slipping or the frame falling apart
lego actually made a crane with pully built into the metal technic hook, that should DOUBLE the lifting capacity assuming the wheel in the pully held out (it wouldnt but i would like to know what its limits are)
Without doubt the most interesting video I've seen on RUclips all day. And as someone else has said, I absolutely thought the red bricks would fail! Seriously, just how strong are they!?
That was cool. Pushing legos to their limits! I was following along for a little bit but i got lost rather quickly. Perhaps do a video with the same concept but with pulleys?
Great Video. Remember trying to get something similar for a mousetrap-car back in school, but never got it working well. There's one thing I don't get tho. Why do you first upgrade to a string that can handle 65kg, but when that tears downgrade to a string that can handle just 25kg?
The video wasn't very clear on that, but did you notice I used the 65kg fishing line only once? The bush and axle broke pretty fast, probably because the string was too thin and hard. I then changed back to the black string that I don't have specs for. After that teared, I went to look for new strings from local stores and found the green/white 25kg which proved to be quite good.
Lubricating the gears will get you faster speed, but negligible additional stall torque, since there's roughly zero static sliding friction on the gear teeth. Lubricating the bearings might give you more torque and should certainly give you better speed and probably higher stall torque.
Test gear efficiency next! use an ammeter to measure power into the motor and time lifting a mass to measure output power. You could test straight gears, bevel gears, worm gears. Bonus points for measuring efficiency at different speeds.
I would have never in a million years had been able to guess that the s-hook would be the component to fail on that last pull... I would have guessed that one of the shafts would fail due to torsional shear long before that hook would deform... Fascinating 👍
*@Brick Experiment Channel* A rough estimate of the formula is: *new_weight = (baseline_weight*2)+2* for every new row of small+large (24/8) gears. then for the next line of gears, use the *new_weight in the place of baseline_weight* Eg: baseline_weigh = 3 kg row 1: (3*2)+2 = 6+2 = 8 kg row 2: (8*2)+2 = 16+2 = 18 kg row 3: (18*2)+2 = 36+2 = 38 kg row 4: (38*2)+2 = 76+2 = 78 kg row 5: (78*2)+2 = 156+2 = 158 kg ... Let's say it has an error window of +-5%, just to be sure.
You should make a video showing all the calculations of torque used behind each system. (I just found your channel and this video is a little older so maybe you already did that but it'd be super cool)
Lego Motors are crazy powerful these days. I still only have the Mk2 technic motors which were somewhat pathetic, but I loved the way they were designed.
lego gears to a solid object. I saw one in the San Francisco museum where the gears are running full speed but eventually gear down to like millions :1 and the last gear is locked to concrete.
Remember that mythbusters episode about lifting an individual with a grappling hook and motor. Mythbusters had difficulties. This guy made it from lego ;)
8:19 apparently "E" on this weight scale thing means "Explode".
Hahahahaha!
I saw it and then looked in comments saw anyone it too :>
Yah dowh

It means Error not Explode.
this is actually ridiculous how a tiny motor can lift so much weight with some smartly placed gears, im actually intrigued

those are hard to use because you can't build them with one line of bricks so they would split at some force
Worm gears and lego Technic would be a good combination. Can build much more robust and compact with Technic.

Aviv Zaberko, if you used a worm gear and a 20t bevel gear, then you get a 100-1 gear ratio. That will be 20-1 then 5-1

use it to wind back a crossbow
Now this is the high quality content I watch RUclips for
Use some lubrication on these gears and you will get more torque whit same power and same gear ratios. I guess something like a 10-20% more torque.
Lubricating the gears will get you faster speed, but negligible additional stall torque, since there's roughly zero static sliding friction on the gear teeth. Lubricating the bearings might give you more torque and should certainly give you better speed and probably higher stall torque.

*@Brick Experiment Channel*
A rough estimate of the formula is: *new_weight = (baseline_weight*2)+2* for every new row of small+large (24/8) gears.
then for the next line of gears, use the *new_weight in the place of baseline_weight*
Eg: baseline_weigh = 3 kg
row 1: (3*2)+2 = 6+2 = 8 kg
row 2: (8*2)+2 = 16+2 = 18 kg
row 3: (18*2)+2 = 36+2 = 38 kg
row 4: (38*2)+2 = 76+2 = 78 kg
row 5: (78*2)+2 = 156+2 = 158 kg
...
Let's say it has an error window of +-5%, just to be sure.
Sion why so complicated? the gear ration is 24/8 = 3. So torque increases at about the factor of 3 (ignoring friction).
Because the legos are acting as a spring so it loses quite a bit of energy from that
I cannot believe there levels of ASMR I'm getting from these videos.
6:11 scared the shit out of me! hahahahahha
You make generally entertaining videos, although there's nothing really complicated here. It's kinda impressive.

it actually amazes me that Legos look so small, but can do so much
Anyone else think that the gears should have had better housing?
Max Mawby Lego Technic would be good for that, but it could be made strong without as well. Agreed.
You should make a video showing all the calculations of torque used behind each system. (I just found your channel and this video is a little older so maybe you already did that but it'd be super cool)
