Touch multiple sides of an opposing teams Mobile goal

Hello, I was wondering if it was illegal to touch multiple sides of an opposing teams mobile goal. If so, can we use a concave piece to push the mobile goal?

Pushing an opponent’s Mobile Goal is legal, so long as you do not grasp, grapple, or attach to the goal as noted in SG6. Please see this Q&A post for more details on this type of interaction: https://vexforum.com/t/answered-definition-of-grasping-sg6/43019/1
