Change Release Notes

  1. Disable Check for ARC Update Added to Preferences: We understand that uninterrupted workflow is crucial for our users. To enhance your experience, we've introduced a new feature that allows you to turn off automatic update checks for ARC. This addition, found within the preferences, gives you control over when you wish to receive updates, ensuring your creative process remains seamless. By opting to update on your terms, you can maintain stability during critical development phases and choose the most opportune moment to access the latest features and improvements.

  2. New JavaScript and Python Command: setVarObject(): In our continuous effort to expand the capabilities of ARC and facilitate more complex interactions between robot skills, we are excited to announce the introduction of the setVarObject() command for both JavaScript and Python. This powerful new command revolutionizes how variables are handled within ARC by allowing you to set variables as objects in the global storage. Read more here

    With setVarObject(), you can now effortlessly pass entire objects, including arrays, multidimensional arrays, dictionaries, and other complex data structures, between different compilers and robot skills. This feature benefits developers looking to implement sophisticated algorithms and data-handling techniques within their robotic applications.

    The ability to store and retrieve complex data types enhances communication and data sharing across various components of your robot, paving the way for more advanced functionalities and interactions. Whether you're working on data analysis, sensor fusion, or AI decision-making processes, setVarObject() empowers you to build more robust and intelligent robotic systems.

    We encourage all our users to update to the latest version of Synthiam ARC to take advantage of these new features. Embrace the full potential of your robotic creations and continue to push the boundaries of what's possible in the realm of robotics.
