The ROSA (Remotely Operated System of Actuators) system is a system I created in order to achieve cheap and reliable onstage automation of objects such as curtains, windows and doors all triggered wirelessly via OSC. Although primarily designed for motor control, the system is flexible enough to output PWM signal and even DMX as required. With a reciever which is small enough to fit in the palm of your hand and able to run of a USB powerbank, the system is small and flexible enough to fit in a pocket or microphone belt pack, yet powerful enough to automate small set pieces.
A breif 10 minute rundown of the system and some of the available modules can be viewed here:

Below is some further information regarding all of the currently available modules, :
Between all of these modules, the system can be attuned to any desired configuration to output whatever the show requires cheaply, reliably and efficiently.
ROSA Job Statement:
I, Ethan Kent, creator of the ROSA system want to make it clear that the ROSA system is not a replacement in any way for competent technical staff. Instead it serves as an aid in order to reduce the risk of backstage crew being put in positions which have the potential to either be dangerous or seen by an audience.
The ROSA system should not be used in situations where the implementation of said system may result in an increased risk of injury to actors, audience members, or crew. Instead these tasks should be carried out an alternative manner.
In instances where the ROSA system can be implemented there is still the need to maintain the system during a theatrical run, and to operate the system during a show. Thus, meaning that there is no threat to the jobs of backstage crew members.
In Summary, The ROSA system could open a window, but it can’t place a vase of flowers on the windowsill, and shouldn’t be used to move the flat into position. As a result of this, it is not a threat to the jobs of technical staff, merely an aid.
