2021.1.1208.2 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 Logic Simulator). 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 > Add Physical Component

It will automatically be attached to a selected GameObject. Otherwise it will create a new GameObject to attach to.
A WheelJoint will be created automatically, this is 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

  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 > Kinematics > Add Kinematics Controller. Make sure the Cube is parented under the Kinematic Controller in the Hierarchy.

     

  3. Add a Control Panel and set the Target

     

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