autonomous sensors

would it be allowed for a team to have an array of sensors on their robot so when one is hit (by the coach or driver) it starts the autonomous program

Do you mean like, prior to the game, to start off the autonomous period, or during the autonomous period? Maybe this will answer it…

"<SG5> During the Autonomous Period, Drivers and Coaches may handle their own Robot while the Robot is in contact with their own Alliance Starting Tile. During contact with the Robot, the Drivers or Coaches may not intentionally manipulate or modify the position of any Scoring Objects (aside from any which are being loaded into the Robot), either by direct hand contact or indirect contact via the Robot. Drivers or Coaches also may not change the configuration of the Robot other than in the act of fixing the Robot (i.e. it is okay to reposition the robot relative to the field, but it is not okay to manually lift up the Robot’s arm).

The intent of this rule is to allow teams to fix Robots that are unable to move, to load Match Loads into the Robot, to reposition and/or reorient Robots, and to activate additional autonomous modes by interacting with the Robot via sensors or buttons. "

yes this helped and answered my question
thank you!!

One of the Q&A mentions something like :
“Allowed and encouraged to operate Autonomous like FLL (First Lego League)”.
You can probably find videos on youtube.
