Detailed Description

Adapts the tracked end points of the operator to the robot's body proportions.

Author:: Marcus Liebhardt The adaptions uses the transforms of the specified operator end points, scales them according to the robot's body proportions and maps them onto the robot. The orientation of each end point is mapped unchanged.

Member Function Documentation

void MotionAdaption::adapt ( )

This method consists of a hierarchy of all private methods of this class. Each method gets called, if the previous method has finished successfully.

Definition at line 182 of file motion_adaption.cpp.

bool MotionAdaption::adaptElbows ( ) [private]

The elbows are placed inside the arm planes at the intersection of the circles around the hands and elbows. Their radii are given by the upper and lower arm lengths. If arms are not completely stretched the normal vectors of the arm planes are used to chose among the two possible solutions. Further additions are made to handle small calculation errors, such as assuming stretched arms, when they are very close to stretched.

Returns:: true, if all necessary transforms have been retrieved successfully

Definition at line 312 of file adapt_transforms.cpp.

bool MotionAdaption::adaptHands ( ) [private]

The hands are placed at their scaled positions. The orientation is added manually in the way that the hands are aligned along the elbow. The plane normals are also used to define their orientation.

Returns:: true, if all necessary transforms have been retrieved successfully

Definition at line 407 of file adapt_transforms.cpp.

bool MotionAdaption::adaptHead ( ) [private]

Simple adaption of the operator's head transformation, which only applies the orientation of the operator's torso to the goal transformation; the position is a constant offset from the reference frame

Returns:: true, if all necessary transforms have been retrieved successfully

Definition at line 90 of file adapt_transforms.cpp.

bool MotionAdaption::adaptShoulders ( ) [private]

A constant offset from the reference frame defines the position of the shoulders. Their orientation is calculated based on the position of the elbows and hands. Therefore arm planes are calculated for both arms, which contain the elbows and hands.

Returns:: true, if all necessary transforms have been retrieved successfully

Definition at line 179 of file adapt_transforms.cpp.

bool MotionAdaption::adaptTorso ( ) [private]

Simple adaption of the operator's torso transformation, which only applies the orientation of the operator's torso to the goal transformation; the position is the same as the reference frame

returns always true

Definition at line 78 of file adapt_transforms.cpp.

bool MotionAdaption::adaptTransforms ( ) [private]

Contains the hierarchy of methods for adapting the several end points of the upper body.

Returns:: true, if all adaptions of the end points returned true

Author:: Marcus Liebhardt

Definition at line 44 of file adapt_transforms.cpp.

bool MotionAdaption::getTransforms ( ) [private]

Retrieves transforms from the operator's torso to the upper body end points hands, elbows, shoulder, head and the transform from the torso's reference frame to the torso.

Returns:: true, if all transforms of the operator have been retrieved successfully

Author:: Marcus Liebhardt

Definition at line 41 of file get_transforms.cpp.

void MotionAdaption::publishData ( ) [private]

Deprecated! Publishes the goal frames as messages. Not used anymore.

Author:: Marcus Liebhardt

Definition at line 41 of file publish_msgs.cpp.

bool MotionAdaption::scaleUserHandsAndElbows ( ) [private]

First part of the more complicated adaptions of the hands: This method scales the position of the hands and elbows using both the body proportions of the operator and the robot.
