Resource kinematics

 



The dynamic capability of a resource is defined by its kinematic skeleton. This kinematic skeleton is a series of interconnected joints forming a chain that controls the motion of (parts of) the resource.


A joint is a frame, a coordinate system, with several predefined motion properties.


Property

Description

Coordinates

The position and orientation of the joint.

Axis

The axis of the coordinate system to which the joint refers.

Type

The type of joint:

Joint_Translation translation

Joint_Rotation rotation

Parent

The parent joint or root frame to define the dependency in the kinematic skeleton.

Limits

The maximum and minimum values of the joint movement.

Max. velocity

The maximum velocity of the joint movement.

Max. acceleration/deceleration

The maximum acceleration or deceleration of the joint movement.

Connect undriven joint

The rigid connection of an undriven joint to the parent driven joint.


The root of a kinematic skeleton is set by the root frame of the resource. This root frame is associated to the fixed part of the resource, from which all (relative) motions are derived.


During simulation, the exact values of the driven joints within a kinematic skeleton are set by the controller that is connected to the resource.
