Grabing on the ground

[DARKAGE]

My team and i where thinking of putting the suction cups from 2007 to grab on the floor to prevent from sliding and holding us in place. but in the rule you cannot grab on field pieces does that count aswell. using the cup to grab and hold the robot in place?

Everything that I have read, indicates suction cups attached from the robot to the floor are not legal.
