Detailed Description

Used for bodies that are part of a robot.

A link is a dynamic body that notifies its owner robot when contacts have changed.

Member Function Documentation

bool Link::externalContactsPreventMotion

(

const transf &

motion

)

Check if contact against a body not belonging to the same robot prevents motion.

This acts like contactPreventMotion, except in the case of a link belonging to a robot. In this case, contact against another link of the same robot does not prevent motion, as we assume the entire robot is moving.

Definition at line 2218 of file body.cpp.

int Link::getChainNum

(

)

const [inline]

Returns which chain this link is a part of.

Definition at line 656 of file body.h.

position Link::getDistalJointLocation

(

)

Returns the location of the distal joint in this link's coordinate system

By convention, in GraspIt! each link's origin is located at the next joint in the chain

Definition at line 2236 of file body.cpp.

int Link::getLinkNum

(

)

const [inline]

Returns which link in the chain this link is.

Definition at line 659 of file body.h.

virtual WorldElement* Link::getOwner

(

)

[inline, virtual]

Returns a pointer to the robot owning this link.

Reimplemented from Body.

Definition at line 653 of file body.h.

vec3 Link::getProximalJointAxis

(

)

Returns the z axis of the proximal joint in link's coordinate system

Definition at line 2253 of file body.cpp.

position Link::getProximalJointLocation

(

)

Returns the location of the proximal joint in this link's coordinate system

The translation component of the previous joint transform gives me the location of that joint in this joint's coordinate system

Definition at line 2244 of file body.cpp.

void Link::setContactsChanged

(

)

[virtual]

Sets the flag that indicates that contacts have changed.

Sets BOTH the worldElement's AND the robot's contactsChanged flag.

Reimplemented from WorldElement.

Definition at line 2207 of file body.cpp.
