Please develop some kind of flag stand, over the many events we have been to we have often had to use broken flags because other teams have had inadequate flag holders. All it takes is an axle vertical.
I woud like to quickly hijack this post. Is it legal to use your arm to prevent another robot from moving, or lifting its arm. Technically it wouldn’t be considered pinning, since pinning is prohibiting all movement.
Also, I don’t believe its entanglement.
I had a discussion with several Refs at the Ohio FTC event about pinning, specifically, pinning a robot behind the crossbar. What they told me was that if a robot was trapped behind the bar and it was clear the robot could not get out then they would start the Pin count. This means that the robot may be able to move a little bit but all effective mobility is lost. How this applies to your question is that if the Refs at your even follow the same idea then yes I believe this might be pinning. However Pinning is defined as “<SG6> A robot cannot pin (inhibit the movement of an opposing robot while in contact with one or more field elements) an opposing robot for more than five seconds. If a referee determines this rule to be violated, the offending robot will be disabled for the match”. From this I would gather that the first field element would be the floor, in your case, thats all that is needed. I believe the refs would call that pinning. You should ask before every tournament to get an official ruling on what interpretation of pinning the refs will be using.
Side note: I don’t think you would be able to effectively keep a robot from lifting it’s arm without pinning it against a wall in the first place.
