To All Ramp Bots.

[Pavan Dave]

To all of the slitted ramp bots:

I have seen many ramp bots with a slit cut through the center of their ramps, and for robots like our teams it would be very difficult to get up. How hard would it be to cover the "Slit" and what would you cover it with?

This is what I'm talking about.

Our ramps don't have slits in them. This is what they look like:

Team 102 Ramps

Would something like that be able to allow your robot to drive up?

I think that the issue with tracked ramps is that those robots (the one you showed and countless others) will not make weight otherwise. Robots always cut it close, and slotted or tracked ramps are built with that weight in mind. Good luck with finding ramps to climb, but i think that most teams who have slotted ramps have that as a final design and won't be likely to change it.

Our "slit" is there for two reasons.
#1 to allow room for our arm
#2 weight

Our ramp is 37” wide it. The slit is 13” wide. Most robots will fall of the edge before they fall into the middle.

Do you have wheels in the middle?

No, they have an uber-awesome crab drive... like us.

Crab drive is awesome, but it is only uber-awesome when you can climb ramps too.

Our tracks are there for a purpose. We used angle aluminum for the structure with the angle 'up' so a driver would have an easier time driving up using the sides as a guard rail to stay on. If you can climb a 17 degree slope and have 1 inch of ground clearance, you can climb us. And I would think that teams would design this into their chassis right from the start.

I was amazed at St. Louis how many robots put zero thought into climbing ramps. We never had two robots allied with us that could climb an 18 degree ramp during all the qualification matches. We never got to test our ramp lift until the quarter finals when we finally had two partners who could climb a ramp.

no slits for us
and have your choice of ramps

No slits for us either.

I’m not sure that crab drive was the way to go this year. This can be a very defensive game.

Team 45 had a very maneuverable robot and a skilled veteran driver but during the competition in St. Louis they added weight to the robot and traction to their wheels and sacrificed a little maneuverability so they wouldn’t get pushed around as much.

I disagree... But I guess we'll see in a couple of days...

[Jimmy Holmes]

I hope we are ok?
