Re: Low bar or not

I would agree with JohnFogarty, it's pretty late in the season to be making the decision for such a crucial feature, as it basically defines how your robot will look.

The benefits for a Low Bot:
-Low Bar
* Your robot can feed balls to a shooter, making you a strong support robot
* significantly decreases time spent maneuvering other defenses if going for pure cycling
- Low robots tend to have low CoG, making them effective pushing robots, a strong consideration for any alliance's second pic
- Potentially better at crossing defenses than a High Robot due to CoG

cons of Low Bot:
-It's much harder to fit mechanisms in, and represents a very significant design challenge to fit a lot of features into a smaller space.
-Shooters are in general less effective, since the ball has to travel farther/you have to take a greater shot angle since you're so low
-Potentially faces robot defense issues, as they are unable to block shots and their own shots are easily blocked


Benefits of High Robot:
-Higher shooting platform may lead to better accuracy
-More space to put components and mechanisms, increasing versatility and value as an alliance captain's pick
-some defenses may be easier if you are able to manipulate the defense from the top
-It's almost impossible to block you from taking a shot
-possibly easier to climb, as your mechanism moves a lesser distance if you mount it high
-Significantly greater capability when loading balls AND playing courtyard defense, as your height will allow you to block

Cons of High Robot:
- Higher CoG means that you may face tipping issues against Cheval, Ramparts, Rough Terrain and Rock Wall if balance is not taken into consideration
- Higher CoG also means that tipping is a possibility against powerful drivetrains or collisions
- You are entirely unable to use the Low Bar, making it easier for opponents to plan their match
- Possible weight issues, due to extra mechanisms
