Bearing blocks from Servo City 545444
A: Per Rule <R05.l> bearings are allowed but non-Tetrix bearing mounts are considered a COTS and are not allowed.

A: The intent of the rules is to allow only the Servo blocks that are listed in Rule <R05.d>

Anti-Static Coatings

However, there are some anti-static coatings that produce a coating that can rub off on the field during a match. These coatings are not allowed as they will result in field damage.

A: Sandpaper is legal unless it's use causes field damage. This includes any damage to the blocks.

and <RG11> "Game elements launched by Robots should not have a velocity greater than that required to reach a maximum of four (4) feet (1.2 meters) above the playing field surface, nor travel a horizontal distance greater than ten (10) feet (3 meters) from the point that the game element ends contact with the robot."
How would a launching mechanism, likely made with elastic or springs, with the purpose of launching an individual robot mechanism be judged? The mechanism would stay attached to the robot at all times, by a cord.
Would it make a difference if the launch mechanism were not to be drawn taught until ready to be used in the game? And of course that it be clearly identified by warning labels on the robot.
A: Launching parts of the robot is not allowed due to concerns over the safety of such devices. Therefore the mechanism you describe would not be legal.

A: Yes, this is legal.
