<p>Read that chapter (169) more carefully then...</p>

<p><img src="https://i.sstatic.net/xytha.jpg" alt="Luffy in Crocodile&#39;s cage"></p>

<p>Here, Luffy <em>stands</em> in Crocodile's Kairoseki cage.</p>

<p><img src="https://i.sstatic.net/2XqdS.jpg" alt="Still in the cage"></p>

<p>Then he states that he has no power. Well, of course, since the cage is made of Seastone.</p>

<p><img src="https://i.sstatic.net/qrbfz.jpg" alt="Smoker kicking Luffy&#39;s ass"></p>

<p>Then Smoker kicks his ass and nails him down. And I think regardless of Seastone any of us would have problems standing if Smoker <em>pushed</em> his weapon to our chest.</p>

<p>So to answer the question: Robin was in a weak state because of the Seastone handcuffs back then, but she could stand because nobody pushed her down.</p>

Maybe i chose a poor example. I'll add a couple where we can see luffy drop to the floor because of the seastone like  at the coloseum where luffy loses his footing after touching the bars. Or the one where luffy and smoker were confined on punk hazard unable to stand up

You should choose pictures for Robin where she looked powerless too. Like when Spandam dragged her all over Enies Lobby to the Gates of Justice.

Also if I remember well Smoker hit Luffy quite some times on Punk Hazard and even that many hits had only a very short effect.

@PeterRaeves you should add picture of Luffy tied in Kairoseki chain in punk hazard where he was talking normally and not showing any behavior of losing his power. Though he is powerless. If Luffy try to use DF power Kairoseki will decrease his energy but if somebody try to stretch his body part it will and he won't feel energy loss. I think its like when there is sudden change we feel uneasy but after sometime it become normal. Similarly when Luffy touch stone for the 1st time, decrease in power make him feel uneasy. Same reason why Luffy acting normal when chained though he is powerless.

Seastone has the same effect as the sea. It does affect energy, health and so on. People with DF powers don't drown in the sea because they "forget" how to swim. They can't, because they are powerless.

<p>In chapter 398 we can see how Robin has enough energy to stand straight, walk around, tell a long story and shout across the ravine, despite being handcuffed with Seastone handcuffs.</p>

<p><img src="https://i.sstatic.net/bNdsbm.jpg" alt="enter image description here"></p>

<p>While in chapter 730 we can see how Luffy becomes completely immobilized after touching the bars of the Colosseum.</p>

<p><img src="https://i.sstatic.net/C8wMsm.png" alt="enter image description here"></p>

<p>Where does Robin get all this energy from? How come her energy isn't completely drained as it was with Luffy's?</p>

probably because the different on its density, they manipulated the kairoseki in both handcuff and Smoker's jitte. It will hard for them if the prisoner can't walk, but with Smoker's jitte, he need to be able to hold his enemy down, so they apply his jitte with more powerful kairoseki, or more dense kairoseki.

They mention the same thing about it in [wiki about those Kairoseki Cuffs](http://onepiece.wikia.com/wiki/Kairoseki#Items) but I don't trust wiki that much

Read that chapter (169) more carefully then...

![Luffy in Crocodile's cage](https://i.sstatic.net/xytha.jpg)

Here, Luffy *stands* in Crocodile's Kairoseki cage.

![Still in the cage](https://i.sstatic.net/2XqdS.jpg)

Then he states that he has no power. Well, of course, since the cage is made of Seastone.

![Smoker kicking Luffy's ass](https://i.sstatic.net/qrbfz.jpg)

Then Smoker kicks his ass and nails him down. And I think regardless of Seastone any of us would have problems standing if Smoker *pushed* his weapon to our chest.

So to answer the question: Robin was in a weak state because of the Seastone handcuffs back then, but she could stand because nobody pushed her down.
