Message Posture3DFloat

class rst.kinematics.Posture3DFloat

A set of positions forming a posture of an articulated thing.

The kinematic structure, which in most cases is required for a useful interpretation, has to be transmitted through other channels.

Code author: Jan Moringen <jmoringe@techfak.uni-bielefeld.de>

position

Type :array of rst.geometry.Translation

Sequence of joint positions in three-dimensional space.

Interpretation depends on information transmitted trough other channels.

The order of entries is significant since the interpretations of individual positions depends on their respective position within the sequence.
