Can mata and kata pick up items on the floor like potions and rune keys? Can some one make me a list of the things they can carried and what they can't carried?

Can those familiar be picked up by a hero or given to an other?

Thanks!

Copied from the Rule book:

Mata and Kata
These familiars are granted by a Wizardry skill card.
Mata and Kata’s speed is 6. Mata and Kata are each represented
by markers that move independently of each
other. The familiars can each be given or pick up and
carry one item (including potions). They can give a carried
item to an adjacent hero (or each other, if they are
adjacent) for one movement point.

So, yes Mata and Kata can pick up items on the ground (aka Potions), but they can not pick up Runekeys, as these are not items:

Rune-locked Doors
Three of the door markers in the game have a rune icon
printed on them. These doors begin play locked and cannot
be opened unless a hero first finds the corresponding
runekey. Once a hero has picked up a runekey, the token
is placed next to the compass rose to indicate that runelocked
doors of this color are now unlocked for all
heroes for the duration of the game. Runekeys are not
considered items and they do not have to be equipped or
carried in a hero’s pack.

Mata and Kata can give items to other characters, not just their owner, but they may not be picked up by anyone... that's just Pico.

This sentence means that mata and kata can take item on the ground and receive some from the heros? I ask this because I think that there is a mistake of traduction on the french game. This sentence was translate with this meaning: Mata and kata can be picked up and give and carried one item...

Sounds like it was mistranslated. There's nothing in the English rules that remotely suggests Mata or Kata can be carried by other heroes. However, they can carry any type of item (including potions), either picked up off the ground or received from a hero.

The things that you'll wish they could do, but which they cannot do by the rules, include: picking up rune keys, opening chests, opening and closing doors, activating glyphs, and taking items from heroes (as opposed to having a hero give them the item on the hero's turn).

Thanks!!!
