Double sine waves are allot of fun. Cue sine scroller...

This guy could probably make big $ doing voice overs - his vocal tones and annunciations are something

What species are those two brown snakes hanging off his chinns?

i saw this kind of robot like 10 years ago in technion?
Anver Dӱzel (10 days ago)
This is so unbelievably interesting
Dirty Poul (11 days ago)
Very fascinating video. I kept asking myself why you'd want to make snake robots, so it was great to have that explanation at the end.
Simo Vihinen (11 days ago)
I think the most important goal of their research must be to eventually perfectly recreate Snake Man's stage from Mega Man 3.
peterJohn gentles (11 days ago)
I will buy one of these robots. Please sell these. Oh gods I need one. Also I can't get over how he has to keep moving it back into frame, it's adorable...

Cue Python programming language joke.

now he needs to get it to play snake

Oh no that snake has taken over his mind. Build me a robot snake army she hisses in his. Yes my master!!!

I feel like you’d want to use pneumatics for snake belly movement.

What a wierd tie

Holy crap! Henry, you're on computerphile! I recognized your voice before I saw you!!!
Daan Janssen (14 days ago)
He has got a great voice for narrating. Maybe some planet earth style robot snake in the wild documentary?
Daan Janssen (14 days ago)
1:36 he looks hungry, you probably should feed him
Dancing Rain (14 days ago)
But... shouldn't a robot snake be programmed in Python?
he said they use Python

This guy is amazing to listen to. Respect for the person, but FTB.
John Quill Taylor (14 days ago)
You should implement Alpha Zero Snake, Self-Learning Code from Google: with merely a dozen lines of code, have it seek most efficient movement, with greatest speed and stealth. - j q t -

"Anyone can string a bunch of server motors together to make a snake robot..." Really????
Naveen Devinda (12 days ago)
yeah, it's just a bunch of servo motors connected in series, each controlled by an arduino individually.. simple as that
Hara Kiri (15 days ago)
Not many places where you can bring your own snake to work: very cool.
Naveen Devinda (12 days ago)
i take my snake and its two eggs everywhere i go..

Amazing research, I'm sure it's going to help thousands of... certainly there are plenty of use... most definitely might help us understand... I'm going to be honest, this seems pretty pointless for a scientific research.

EZ - rapid locomotion across a loose sediment surface, like say - Mars sand that your rovers will get stuck in.

This gotta be the most awesomest dude on the planet. And suddenly my fear of snakes is just gone! More plz :-)

I'm too busy paying attention to this guys beard and the sound of his voice

This guy communicates very well, would love to see more of him
Harshit Sinha (15 days ago)
A guy with a forest beard with a snake around his neck researching in Computer Science. The world can be weird sometimes!!
Dude, is this guy a professional voice announcer? Should be! Another cool video, another cool scientist.

One day he will get too close to a paper shredder and that will be that.

This guy needs more neural nets! Nobody uses old fashioned control theory algorithms anymore!
Dalton Growley (15 days ago)
Im surprised that they use servos instead of a series of hydraulic sacs.
*ArcanHage* (15 days ago)
More videos about robotics plz!!!
xbzq (15 days ago)
Robots have no habitat. Also, who's paying this dude? If it's a hobby, fine, but this isn't a job! Also, "snake locomotion" isn't a thing. Using 24 motors is probably moar efficient when using WHEELS. Bit old fashioned, granted, but quite effective.

Snek bot!
Andrew Walker (15 days ago)
OK is it just me or does his voice remind anyone else of Snake from the Simpsons??? Like if Snake had a PhD

Kurt E. Clothier (15 days ago)
Nice. I used the lynx motion servo controller way back in grad school to control an arm, and later in my robotic flower girl. I've since developed my own drivers, but it's a great, low cost board to start with.

That's one crazy beard. I low key like it.

Really interesting clip. This guy knows his snakes.
Kartikeya Luther (15 days ago)
I just thought all the time... leave the robot snake alone let it do its movement without touching it all the time. Why must he touch it all the time..? Really annoying.

Very interesting. I think I spotted one of Theo Jansen's Strandbeests on the bookshelf.
His beard doesn't lie: a long time Debian user

Wow this man's beard is a complement of mine.
Bo Broadwater (16 days ago)
Holy cow! I knew Henry when he was a postdoc and I was a PhD student at Georgia Tech. My mind was blown when I saw such a familiar face on one of my fav YouTube channels 😄. Henry, if you see this, I hope all is well man!
Dave S (15 days ago)
his beard wins though right?

If you're more interested in robotic snakes, there is a Norwegian company called Eelume developing them for off-shore oil and gas applications

What type of snake does he have on his shoulders?

Jeremy Foor (16 days ago)
Snakes are my #1 fear. I hate them and they give me the creeps like nothing else ever has....but this video was fascinating. After the video I can understand why a snake-like robot would be beneficial. Dr. Astley was very well spoken and you can tell he has a real interest and enthusiasm for his work which is admirable.
Timmy Blank (16 days ago)
The robot will do the the same thing every time!!! Yay come back to me at first robotics tell my team that

i think to solve the problem with energy, u can make a tiny battery for each one 'cell' of snake, and each will works separated, its a lot of battery, but its a thing what u can think about.

"How to Python"
Mpampis sougidis (16 days ago)
Maybe you can make this project more energy efficient by not using arduino based code???
Vinxian1 (15 days ago)
+Mpampis sougidis but the power consumption of the controller is so much smaller than the power consumption of the servos. In comparison it's not really relevant
Mpampis sougidis (15 days ago)
I mean more energy efficient from the mcu perspective (not from servos). Wouldnt be better if he used bare metal programming or some rtos?
Vinxian1 (16 days ago)
Because arduinos magicaly make servos draw more power

Why can't I have a professor like this who walks around in the hallway with a snake on his neck?
Debabrata Acharya (16 days ago)
I want to understand his beard.
YourTV Unplugged (16 days ago)
Spy on a "bad guy" in his house? You better have a warrant for that snake, otherwise YOU'RE THE BAD GUY! And so a snake is quite fitting... Anyway stick with the more interesting reasons, there's already enough ways to do that, there need not be more! :)
miksa (16 days ago)
I learnt nothing from this video because I was just looking at his beard the whole time, very interesting.
KuraIthys (16 days ago)
That snake there, just nonchalantly acting like a necklace the whole time... XD
Matthew Newey (16 days ago)
I'd like to see him do another video with a Boa constrictor.

This guy is so cool!
Vojtěch Janků (16 days ago)
I haven’t watched a Computerphile video in a while, but I clicked on this and stared with amazement for the whole twelwe minutes. This guy was just constantly spitting out a stream of interesting things from between his epic beards. Please give us more of him"

what kind of snake is that? its cute 🐍

I think he said it's a Taiwanese Beauty Snake but I may have misremembered >Sean

The origin story of Snake Man from Megaman 3.
Urpo Lankinen (16 days ago)
Sure, Snakes are good at going through cramped corridors. But I think Computer Science should turn their attention back to the noblest yet humblest of reptiles, the Turtles. Computer Science has modeled basic turtle movement on surface - turns, movement back and forth, and ultimately inconsequential things like holding a pen. But millions of years of evolution prepared Turtles to be some of the most epic tunnel diggers of the Reptilekind. Why is this not modelled yet? That's the real interesting field for scientists who want to break new ground.
