Ramp bot vs. Arm bot - Page 3

Fe_Will · #31 20-01-2007, 11:01

I my opinion a ramp bot is only as good as the drivers on the alliance. Trying to drive a robot on another bot with the same footprint is difficult at best. And I know that all teams will build to the fullest dimension possible making the task even more interesting.

The one thing I learned last year is that 30 degrees may not seem like a lot but many bots required a running start to get up and the number that rammed the back wall was staggering. Now imagine the back wall is your arm.

That might depend on how clever the ramp design is. 27" wide ramps on top of the robot don't need to be only 27" wide on the floor.

Good point. Although I don't think that that would happen often. Any team that can adequatly create a robot with a working arm and a ramp then I think that they would be able to find some way to shield it or protect it.

Ramp VS. Arm? How about both, duh...

The perfect alliance is 2 score-bots and one lift-bot.
this is because with three score-bots the other team is able to score without anyone trying to prevent them.
with one lift-bot the other team has atleast one bot trying to prevent them from making the points.

Who says a scoring bot can't play defense, keep in mind ties in your record are decided by the average number of points the losing alliance in each of your matches had, it is in your best intrest to just score more than your oppnents can rather than prevent them from scoring.

Obviously it would be best if you could make a ramp and arm bot. But it would be hard. Especially because an amatuer driver on your alliance might crash into your arm and damage it. I think that it is better to focus on one attribute and then if there is time, try the other one.

The perfect alliance would be 3 scoring robots, with atleast one with ramps as well.

the way i see it,

if you go for arm bot, you really need to know how you want to play the game, and come up with the right strategies for it. If played right, it will obviously be a great advantage for your alliance.

as for the ramp bot, it could easily become a decision maker for any match, because if you are in fact able to lift those robots high enough, that's a big chunk of points.

2 cents.

Here's what I'm thinking: What if your goal is to build a robot with an arm as its main attribute, but you're team is feeling ambitious and decides that if they can lift two robots 4" off the ground, that would make the robot that much more desirable. So you build the bot and you do reasonably well in the qualifying matches, but you still need to be picked by someone to play in the elimination round. If the top-placing teams are looking for a good ramp bot, wouldn't they want one that can lift the robots 12" up, making the ramps superfluous as a desirable feature?
How likely do you think it is that the top teams will want a 12"-lifting robot on their side?
Do you think that some would value 4 inches and an arm more than the above or do you think that a robot like this will have to rely on simply their arm to get picked on an alliance?
Will the points that a robot with 4" ramps wins off of them in the qualifying matches be enough to make the ramps worthwhile?
Just something else to think about...as if we needed more...

SSMike · #42 20-01-2007, 21:32

Thanks for replying. That was a really good point. I think if the you have a ramp bot and are not one of the top 8 seeds at the end, then you will probably be picked. This is only because I think that arm bots will make up most of the top 8. If you have 2 or even one arm bots, they are going to be looking for a ramp bot. So if you have one that elevates 2 bots 12 inches off of the ground, then you have a good chance of being picked.

If that ramp bot also has an arm that can score, if not perfectly, but here and there, then they will definitely be picked.

Just my opinion. Good luck at your competitions!

I know atleast 3 teams doing it, I only know of three because I have only talked to 3 teams.

I'll ask the Team it would be cool to meet someone from another team that is in the area

It happens every year ... most people grossly underestimate how hard it will be to score, in any fashion.

This year we have the "we are going to do it all" people. If you can do it all, then great, but I doubt you will "do it all" well. In this game it is not necessary to do it all. Not by a long stretch.

A good team who concentrates on being a two robot lifter will have a better two robot lifter than a good team who tries to do it all.

A good team who concentrates on being a fast ring scorer will be able to score faster than most of the "do it all" scoring robots. History has shown this time after time.

Now there will be the top few percent of teams who will do it all, and do it better than most, but it will not at all be necessary. This game needs great scorers. This game needs great lifters. This game is played by 3 teams playing together and will be won by 3 teams that combine to have great scoring and the ability to lift.

And of course, we will be doing it all
