Is the U.S. educational system SO BAD that NO ONE noticed this?
''The robot weighs 17 grams, ... able to pull a 20 kg weight. Just 6 of these tiny robots can tow a car. '' (there is an error here, that car would weigh 120 kg)
*Either the robot can REALLY pull 200 kilogram weight OR 60 robots (of 20 kg capacity each) can tow a 1200 kg car* !!!!
@chadcrocfrield Says:
you look like tony stark wich i like it
@TbjrL Says:
this would be a good idea for those stupid portable TVs
@jeju777spidyandmusiccreator Says:
is there a place where i can buy gecko adhesive?
@crispychrissy Says:
10:08 I have never heard someone pronounce produce as “prah-doose” instead of “pro-doose”.
@jah4881 Says:
blablabla just climb the wall
@emirhanozdemir1063 Says:
Is it possiple, make them as tank tracks, and make the robot drive up the wall? Maybe reverse down as well?
@Mak_The_Great Says:
"Cannot make what a gecko has" and yet Ignorant humans believe it came into existence from nothing, by no creator.
@TheOmniBandit Says:
2:15 hmm? *rewinds*
*Spiders or other insects*
WHAT!?
@qunxiuzhu1507 Says:
where can I buy sum
@aliosmansahin1729 Says:
Now, meet the new dinosaur character which will be in next Jurassic park movie.
@joshmellon390 Says:
I enjoy your videos when I'm having a bad day. Thanks for the brain food..
@JohnFiqzer Says:
please climb a building with gecko adhesive
@averageyoutuber113 Says:
so is it more effective than a super smooth flat piece of silicone because the micro ridges can conform to the surfaces better at a micro scale
@Waffel099 Says:
where do i buy this material?
@AsteriskIRW Says:
Now make them into gloves and sell them.
@etrazin7735 Says:
theres a team that created a nano web like structure to help the human healing processes, what if they cut it to make small gecko like skin
@teddeebayre3433 Says:
The Gecco has conquered nuclear physics.
@joshuasolt5005 Says:
It's so advanced that we cannot replicate it, yet it's supposed to have occurred randomly. Hmmmm...
@notoverlyacerbic9574 Says:
What in God's name is
"Prawduce"?
@Mortem201 Says:
Any smooth surface you say? 😏
@Not2day-Satan Says:
First thought, i need tires made of this material.
@surmuffin1945 Says:
I need gloves with these grips.
@DonP83 Says:
God is awesome, we can see how He created Geckos feet and still can't fully duplicate it because it is so intricately formed. Pretty cool.
@stevendwiga1561 Says:
AWESOME!!!
Now do a video on how chameleons change color.
@AasthikKPuthuval Says:
If we can't replicate the gecko's leg, then why can't we just take the leg of a dead gecko and use that?
@Derp_Wolf Says:
9:59 Tires, the most obvious application is for tires. Probably race cars, since a race prepped surface is so smooth. That or golf carts used in shopping malls or airports. That sort of thing. Such a tire could have really good grip under acceleration and very low rolling resistance while coasting.
@Doingstuff56789 Says:
Grip?
@zanderdiedricks1895 Says:
Pretty sure this is because of the Van der waals force
@ChrisJ82 Says:
Can the adhesive break or wear?
@whengale Says:
Has anyone tried replicating this at home? It seems like you could configure a machine to make the razorblade cuts fairly easily, especially for someone with some specialized robotics or CNC knowledge.
@B3anZfr Says:
Isn’t it that material designed to mimic gecko skin?
@lionelonkruid3303 Says:
I really wish someone could just make a glove or something
@금강이조은 Says:
only mimic creator
@schneemannX Says:
I saved 15% on my adhesive by switching to
@thephantomarmor Says:
What i understood from this vid is that gecko uses electricity to climb? Idk im not good in physics😂
@Tommy-c9n Says:
nice
@babycadybug Says:
yes
@OnkarJadhav76 Says:
I've seen this stuff more than 5 years ago on television and still don't know where to buy it. Same thing went with that spider goat fabric. Where do these things go? I dont care about all the science if it is not accessible.
@rizzG9717 Says:
its new for running shoes
@thenextgen1able Says:
Prahduce.
@Stephen-uz8dm Says:
Who do i pay to CRSPR my hands and feet into growing surfaces like this?
@imareader01 Says:
Make the mold softer than gecko’s feet and have them walk in it. Boom, gecko pads. Or lasers. Lasers could work. Expensive though.
@AriThau133 Says:
I wonder if that could be made out of a textile instead of silicone? Special extruded microfiber?
@ThatGuy-k6g Says:
0:58 Legend has it that he was bitten by a radioactive gecko. Now, he can do everything a gecko can.
@JosiahLane-d1d Says:
And that’s just another example of God’s amazing creation. That kind of intricate design isn’t accidental.
@eamonia Says:
Material sciences are _sooo_ cool... 😎👍
@michaelabratzel6371 Says:
Plottwist: they can't produce it. It's cruella skinning gecko feet.
@A-T-M- Says:
7:26 Now we know what experimental tires Adrian Newey was talking about for his Red Bull X10.
