scoring in center goal from platform

[Daniel_H]

how can an opponent's robot pin me on the platform if they have to be in a 30º ramp (maybe less because some of them can put the front wheels on the beginning of the platform, but yet....)? Well, it's possible but our chances to get rid of him are higher

the problem with that is that your speed is limited to something like 28 mph
and its to far to shoot with that much speed


hope this helps

A few people on my team (including me) were joking about a robot that could climb the Plexiglas with high strength suction cups mounted on "climbing arms" and then pour the balls in the center goal. Of course they could never hold the weight and I don't want to think about what would happen if the robot fell.

I'm sure if you got up there your accuracy would be very high but you have to keep in mind how long it will take you to get up there and how long it will take you to go back down and reload. If you only have enough time to get up once you might not have time to reload and do it again. Also, if this is your only means of scoring then with a little bit of scouting opposing teams will figure out that you need to get up there and when they are on defense they will just put a bot in front of the ramp to prevent you from getting up there and leave you totally ineffective. It could be an effective strategy but I wouldn't count on it.

I find it funny that people are dismissing doing this quickly cause you don't have the height to jump. (What's up with that?)

7" is a lot less to worry about shooting to then a 15-20' shot from quarter field accurately.

Hasn't anyone ever heard of a finger roll?

Get on ramp, if someone traps you against the wall, who cares, they can't hover over you if you are max height.

Shoot with backspin much slower than 12m/s to prevent penalties and get ball(s) in goal.

I think this is a great strategy, and something even a rookie team can do once they figure out how to gather balls effectively, and make a nice release system with some backspin.

I see this being the 2nd simplest of robot designs, and only one step up from a herder/lower goal scorer.

The most challenging part (and testing with my team tonight proves this real easy even to just do that) will be to actually get on the platform.

Has any one thought about instead of shooting if u could figure out how to get it high enough in the air but instead of a shooting the ball have the bot to kick it.

See, if I were defending against a robot doing the finger roll, I wouldn't bother pushing them against the wall. That's where they want to be anyways. I'd jump up next to them on the ramp, then shove them sideways to the edge of the platform. Pin them there if I can, but they wouldn't be scoring any time soon after that. This is assuming I can push them around and they can't push me, of course.

If the ball goes higher than 60" and then you try to kick it (think of it as a spike in Volleyball), you will be penalized for a height violation.

If you are talking about a (football) placekicker effect mounted on your bot below 60" to shoot the ball into the goal, that's an interesting concept, and to tell you the truth, I hadn't considered that.

hehehe.. Now that you said that out in the open, I would add a curved multi-positional attachment to my shooter to shoot from anywhere on the ramp. Your best defense would be to get me pinned in the corner of the ramp between the lexan wall, and the players station wall, so my angle of shooting was so unbelievably shallow, it couldn't make it most of the time.
Or any of the time in some cases.

But, if I designed a drive system with enough torque because my object was to get on the ramp anyways (new cim motors) good luck pushing me.

also if u go with a shooter how are u gonna manage getting the balls from ur holding area to ur shooter without over filling ur shooter.

The platform surface is made of daimondplate right? (I read the field elements materials list) In addition, you may want to consider the grip your treads provide on the platform. For defensive/offensive purposes, even a robot with enough torque may be beaten if its wheels are not well suited for a smooth surface. Eg. skyways haha. (for that matter skyways probably won't even provide enough grip to get up the platform).

And if you are scoring from the platform, at that angle it may be difficult to score if the firing device is low to the ground. My dad suggested using the angle of the ramp itself to allow you to aim balls at the goal.

I wonder. If you didn't want to be pushed around, maybe pneumatically deployed suction cups would do the trick. Sure, maybe you score 15 points for the opponent, but if your robot scores every ball and your bot is loaded with a ton of balls, you may walk away the winner.


*runs off and dreams new robot*

Correction. The Ramp portion is diamondplate, the platform portion is made of Lexan on the top most layer (the layer the bot would be sitting on), and the sidewalls are also Lexan.

See... I don't try to contemplate defending against robots that can push me around and score at will and a bunch of other things. Exercise in futility. Also, one of the kids did some geometry on the goal profile at different areas on the field. It gets remarkably bad remarkably quickly, really.

Also, off topic, but why is everyone so hot on the new CIMs? They're neat, and have half the revs of the smaller CIMs for less gearing, but they also have 60W less peak power. The only advantage is the increased efficiency. And the gnarly faceplate and lack of mounting holes.....
