The rules call for a "rigid fastening system to form a tight, robust connection to the main structure/frame". Does your mounting meet that requirement?

In generally, inspectors look for two things to determine if it is a robust connection: What will happen during normal game play (we don't want to see your bumpers falling off!), and what will happen when a student picks up the robot by the bumper (We don't want to see it breaking off!)?

IMO, mounting with just those short sections of angle on the sides is probably not robust enough.

And as for the tape... a lot of inspectors and LRI's read Chief Delphi here. If a team at one of my regionals posted on here that they used tape in the bumpers and I saw the post, I would feel obliged to ask them about it at the regional.
