Monica's Icosatetraped

[Animoution]

Its amazing.

and it's got an apple thing lol.

wathever.

Its creepy D:

[1888junkteam]

excellent work!

excellent work!

I have few questions to you:

1) Couldnt you have reduced the number of solenoids and form a different gait mechanism this is to reduce the whole weight of the robot. ??

2) In what way did you calculate how much of air pressure is required for your robot.

3) Why were you using such big compressor's??

Well I am askng this because of I was designing my robot underwater using softer legs which would use suction mechanism to stick to the ground and move forward. And your idea stuck to me.

[notgud20]

But was not able to understand how to implement it. Thanks for the whole video I did understand it clearly. But I need to design in such way as to reduce the number of solenoids and the whole electronics part. But seriously great. Hats off to you.

Thank you once again and looking forward for the answers.

Electronics is cheap; This was a research experiment to determine if soft legs would work at all. I would have used something like an Arduino if I was doing it for real.

It's the energy for the compressors that dictates the design and this is hard to get around, although fewer legs, light legs, and a lighter bot overall all contribute to a lower energy optimum total mass balance.

Battlebots often use bottled pressurized nitrogen as energy source but it's relatively expensive.

[syntience]

Three-stroke motion appealed to me. It went with the three tubes per leg theme. Because of the three-stroke, this one would require the band to play a Mazurka if it was to parade.

Atmospheric pressure is about 14.7 PSI. Vacuum doesn't get better than that. For balance, I decided to aim for 10 PSI either way.

I needed rotary vane type for continuous flow. And the flow can be computed from the deltas of the leg volumes. And I needed DC operation. And I wanted the 10 PSI.

nicely done great job

do have a look at this as well POPPING AND LOCKING DESI STYLE

pretty cool and entertaining

c the whole thing for real fun....

[GRAHAMAUS]

A lot of idiotic negative comments - but actually, that leg triplet is a cool way to position something in 3 dimensions cheaply, so could easily have lots of applications. I'm interested in how you interfaced the Mac to the hardware, and what software it was running?

[syntience]

I used a Keyspan USB to serial converter and the serial-to-parallel converter from Electronic Energy Control Inc. (Columbus, OH). The EECI required an expansion board to get to 24 channels, and three Reed relay driver boards. The code was written in C. It was trivial to open a byte serial output device in /dev (which automatically appeared when I plugged in the Keyspan box) and write to it.

What?, you are a girl?

i'll be damned

[jackhallowatt]

WOO! WOO! get on board the pneumatic macintosh walking machine!

[ThaDmo541]

Next step: Make it ride-able! It would be like a magic carpet ride.

[TheNewVideos]

pointless. Well, maybe it is a jumpingboard for some new robots with similar things, but a lot better

[latsot]

@TheNewVideos Since when is building something pointless? It's a lot less pointless than writing idiotic messages on youtube.

[TheNewVideos]

No you see what I mean is, that we see all sorts of robots, but how many of them have a goal, how many of them are useful and have a potential to be used in action, whatever action that is? Pretty few.

It is a cool robot, I agree, but still useless.

[latsot]

And my point is why should they have to? You don't criticise art for having no practical function, so why do robots have to be 'useful'?

[TheNewVideos]

Would you spend a lot of time and money to built a robot, that has no views of being developed to something useful? I would not. It should atleast be a toy and amuse you. This here is not. But I think this here is just in some development stage and will become something.

[latsot]

Yes I would. Because I would *learn* something. Very likely, a lot of things. And I would have made something that nobody else ever had. Also, I would document what I'd done so that other people could use what I'd learned.

[TheNewVideos]

Thats good. I am a robot fanatic myself and I am disappointed in the robot development a little. Does not make much sense, as far I have seen documentaries.

[latsot]

Carry on watching tv shows and not actually bothering to make a damn thing. Be sure to complain about people who have more gumption than you do.

[TheNewVideos]

Wtf, I did not say anything bad about this robot here and you people jump in my face. Fuck you!

[syntience]

My bot showed that soft legs will work. Before I built it I didn't know if it would work, and possibly nobody knew. Now everyone knows it will work and we can carefully design better things built on this principle. When exploring new areas you may want to first do the cheapest test that can tell you something you didn't know.

We are spoilt by only seeing finished products like iPhones. But buying good products is a lesser joy than building something or discovering something.

[TheNewVideos]

You are right about that!

Keep up the good work!

What the next step on with this robot? Any tasks planed?

[zahraj]

Nice piece of work.

[evolutionsdisaster]

Superb, great, amazing

I liked the explnation of it more, obv icosotetraped is more amazing.

[pbill23]

so can we see it move about?!?!?! sure looks cool....

[stolkachev1]

Great job Monica! And very nice explanation.
