grab a object

[FirstSanny]

How can we grab an object if we stand next to it?

[Ju1yy]

We can use
bool ALRobotPostureProxy::goToPosture(const std::string postureName, const float speed)
to make the robot sitting (Posture is "Sitting" ?)

And i found
void ALMotionProxy::closeHand(const std::string& handName)
where handName is “RHand” or “LHand”. I'm not sure if this method does the right thing, the API says
Closes the hand, then cuts motor current to conserve energy. This is a blocking call.
Maybe we can grab an object with this method, or maybe not. But if we can, we need the perfect perfect position of the hand that it works

-i don't know how to catch the ball because i can't see a function for the hand. we should ask the professor how todo that. The perfect way to do that is making a new posture of our robot catching the object, but i don't know if we can do that. we should ask!
