From looking closely at the pictures, I notice your robot have two v shape metal pieces that push on the wood bar so the whole robot will pivot over the bar. But those metal pieces look pretty thin…

Well, I know that your team designed those piece so that it will take the force as the robot lift itself off the ground. But how about the wood piece? With so thin of metal piece the ends of the arm are going to rip into the wood. Maybe even cut a piece of wood out. I don’t know… It looks awfully sharp to me.

Also, with the whole weight of the robot twisting the pipe around the wood piece (because that the more stable part), I am wondering if the torque from the arm will bend the pipe toward the field. After all, the pipe is pretty long across half the field.

I am not trying to be picky about the robot, but just want to raise some concern about damaging the actual field.

By the way, to my understanding the wood piece at under the bar is a 4X6. Make sure you check the blue print or the BOM. You want to make sure your metal v shape actually fit that wood piece.
