V2020.1.56.3_ Limited Servo Motor



Overview

The Limited Servo Motor is a component to simulate an accelerated rotational motion on an axis. It consists of two components; Physical and Logic. Both are needed to control the motor through a logic adapater (connecting the Limited Servo Motor to an external controller through a https://unit040.atlassian.net/wiki/spaces/PUD/pages/280987237 ). Adding a Control Panel gives you the option to control the motor.

 

A succesfully created Limited Servo Motor shows up with this gizmo.


Where to find

The Limited Servo Motor can be found under

Standard Components > Motors > Limited Servo Motor > Physical Component / Logic Component 

It will automatically be attached to a selected GameObject or otherwise it will create a new GameObject to attach to.
A https://unit040.atlassian.net/wiki/spaces/PUD/pages/281673729 will be created automatically as part of the component.

Selecting the newly created GameObject gives you the following menu in the Inspector.

Please note: this is an example of a GameObject with the Physical Limited Servo Motor component.

How to use - Physical Component

  1. Add a Limited Servo Component to a GameObject, in this case a simple cube

      

  2. Add a Kinematics Controller, this can be found under Mechanics > Add Kinematics > Kinematics Controller. Make sure the Kinematic Controller is visible in the hierarchy and not connected to the Cube

     

  3. Make sure the Cube is parented under the Kinematic Controller in the Hierarchy

     

  4. Add a Control Panel

      

  5. Set the Target

     

  6. Press Play to see the rotation of the cube, controlled by the Limited Servo Motor
