Servo Motor Template component
Base component for creating custom servo motor simulations. Recieves messages from the the 'Servo Controller' component.
Macro 'SetTarget' allows external objects to be moved by the servo for mechanical simulations.
This component can be used as a base to create child components
The following components all inherit the traits of Servo Motor Template:
 Micro Servo (Tower Pro 9g)
|
Small size 9g servo motor suitable for control by the 'Servo Controller' component.
Use the 'Link to...' property to attach other objects to the rotor for emulating mechanical systems. Send a virtual PWM signal to the servo by selecting it as a target of the 'Servo Controller' component. |
 Standard Servo
|
Standard size servo motor suitable for control by the 'Servo Controller' component.
Use the 'Link to...' property to attach other objects to the rotor for emulating mechanical systems. Send a virtual PWM signal to the servo by selecting it as a target of the 'Servo Controller' component. |
Examples
Please note that the servo motor template and child components require the Servo Controller component to control them.
Controlling a servo with an analogue input
This example reads the value of the analogue potentiometer and uses this to set the position of the servo motor.
Servo Example 1
The Servo controller is linked to the standard servo component but this could be linked to any object on the panel.
Creating a multi-axis actuator using servo motors
This example links two servo motors together using panel primitive objects and groups.
Servo Example 2
The Servo controller can handle up to 8 motors and is used to control both of the standard servo components on the panel.

SetTarget
Set a panel object to be 'connected' to the servo's.
The connected object will then move as if connected mechanically to
the servo's actuator.
Parameters
- HANDLE Target
- Object to be moved by the motor
Return value
- This call does not return a value
Property reference
Moving Part
This property is of type Panel object and can be referenced with the variable name moving_object.
Set an object on the System Panel to be the servo's actuator.
The object's position at the moment of selection is taken to be the 'rest' position of the actuator - the
maximum and minimum angles will be measured from this position.
Axis Object
This property is of type Panel object and can be referenced with the variable name axis_object.
Set a panel object to be the centre of rotation of the servo's actuator.
Move Around
This property is of type Fixed list of ints and can be referenced with the variable name rot_axis.
Set the axis around which the actuator will revolve.
If an 'Axis Object' is chosen, this will be a local axis of the chosen object, otherwise it will be the
current world axes.
Minimum (degrees)
This property is of type Floating point and can be referenced with the variable name rot_min.
Angle that the servo turns when the PWM signal is at its minimum.
Measured from the actuator object's 'rest' position, chosen at the time of connecting the object.
Maximum (degrees)
This property is of type Floating point and can be referenced with the variable name rot_max.
Angle that the servo turns when the PWM signal is at its maximum.
Measured from the actuator object's 'rest' position, chosen at the time of connecting the object.
