I admire your robot very much. Another great effort by
BMS and the gang at NBTHS.

I have to questions:

#1 Is your robot done or are you adding more goodies to
the robot as we speak?

#2 Do you thing the railing can take that torque your
machine must put into it as you lift yourself? I see
that your barrier simulator is not supported the same
way that the real barrier will be (no big gussets on
each side of your robot as is goes over the fence).

To be honest until I actually yanked on our practice
field's barrier, I was sure you would just pull the
whole thing over. Now that I have evaluated it with a
new eye, I think it may be strong enough after all.

So... have you tried it on a "regulation" barrier?

Do tell.

1: yes we are adding some other things to the robot but until they are finshed i do not want to say What there are because i do not want to give the wrong impression
2: We have not done it to the full bar yet but i do not think we will have a problem because it fits the the 4X4 on the bottom of the rail

I thought is was a 4x6 that ran across the entire field..

maybe you mis-spoke.. or (i couldn't believe it :-P) the drawings we used were wrong in another place

just wondering.. hope i'm wrong or that functionality is built in

Yeh, AFAIK when we looked up the specs for the bar, it was 2 2x6 pieces of lumber with a 3/8 inch piece of plywood sandwitched in between. Making the overall width 6 inches and the total hight 4 3/8 inches. At least that's what the manual we had said.

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.

ok the arm, WILL NOT destroy the feild in any way shape or form. The arm does not touch the top of the 4x6 but the sides.
