Move object(s) to default position

Previous pageReturn to chapter overviewNext page

In of this task, the human model brings the object to certain position in relation to its own hip coordinate system. This task can be used to adopt a suitable object carrying posture.

 

Subordinate tasks:

Move object(s) to target

 

Parameter

Type

Mand.

Meaning

Object to move

Object

yes

An object parameter defining the object to be moved.

Body movement type

Selection

no

A selection parameter used to select to the upper body motion to be used.

Target height/

Distance /

Transversal position

Selection

no

Several selection parameters that define the relative target height of the selected object in relation to the human model coordinate system and the distance of the selected hand(s) forward or toward the center of the body.

 

By default, all three parameters are set to automatic, determining an achievable, ergonomically favorable, and collision-free carrying position. The carrying position can be adjusted manually using the additional selection parameters.

Reference bodypart

Selection

no

A selection parameter specifying a part of the body to which the object is to be moved. Mainly used for putting on/attaching protective clothing. To function correctly, the coordinate system of the part to be put on (e. g. helmet) must be aligned with the coordinate system of the part to be picked up (e. g. head) (see figure Example: reference body part "head" and helmet).

Target to look at

Position

no

A coordinate parameter representing the point at which the human model will look.

Change object orientation (both handed only)

Checkbox

no

A decision parameter determining whether the object will be turned during the motion or whether it will maintain its orientation. The parameter has an influence only when the objects are handled with both the hands.

Local 'object up-direction'

Selection

no

A selection parameter defining the local axis of the handled object which shall be turned “upwards”, if the option “turn object” is active.

Allow change of grip

Checkbox

no

A decision parameter determining whether the hand or the object need to be manipulated to match the orientation constraint between the placement target and the object. Disabled by default, i.e. once found or manually set grip points are retained in position and orientation. When activated, the ergonomically best possible grab point(s) with the best possible orientation is/are selected at all times during the object movement.
