Hello BEST teams,

Many of you are aware of the run time issue with the Arcade Module block in VEX Simulink library. We have a fix for the issue and we are currently adding the fix to the official library, however it will not be available until late October. Thus, I am submitting the fixed block here in this post as an attachment.

Please download the attachment ZIP file that contains the fixed Arcade Module block.

Use this block in your own Simulink models and let us know if the fix resolved the issue.

NOTE: This block is now fixed to work as expected on the real robot. Do NOT use this block with the Field Simulator block this year, since we are still trying to fix the simulator block to function correctly with the Arcade module block. Sorry for the inconvenience. Our development team plans to fix the Field Simulator block issue with Arcade Module block in the next release. 

Do feel free to share this fix with other teams who might be running into this problem (Yes, helping other teams is great sportsperson spirit!).

If you have questions or concerns with this fix, please post here or email the support team at

Thanks and all the BEST!
(makers of MATLAB and Simulink)
