Will a solid piece of metal extension, like a linear slider, be allowed to be used with the purpose of helping a robot push another robot away from a goal stash? Which one of these examples will be considered legal?
A c-channel or a linear slide as a blunt, small extension that can get between (not inside) the field wall and the drivetrain of a robot that is surrounding/defending a stash
or
A short piece of c-channel or a linear slide that can be used to gain leverage against other parts of the robot, such as its tower mechanism
Edit:
Both of these mechanisms will be short in length (less than 2 inches) and therefore, in my opinion, should pose no risk of entanglement, nor are they designed to cause damage to opposing robots.
