We are trying to decide on whether or not we should have our robot be more on the light side or should it be heavy?
We were thinking that heavy might be better so that the opponent wont be able to push us around, but then that might burn out our motors faster. But if we do light, then we could be easily pushed around.
I’d suggest building light and look into other methods to prevent pushing. Those other methods could include locked omnis, traction wheels, pneumatic brake, using break type hold, or using a active break program. Building heavy robots both puts more wear on your notes it also increases the chance of wearing down mechanisms. Most important it slows you down during the match which could cost you the win.
It can sometimes be useful having a little bit of weight to throw around, but it’s almost never worth it to intentionally be adding weight where it could be lighter. There are much more effective ways to be defensive that don’t make the robot heavier, and being light is just always going to be more efficient on your drive motors.
It all depends on how you intend to play the game (and hence the importance of game analysis).
Latching on technik3k example of 169a TP robot - that season we actually had 2 very contrasting style, and both highly performing robots that were alliance and went on to become the worlds div champions.
169a - light and fast flywheel, with wedges at the side
8059a - heavy and still (deceptively) fast enough, with locked omni and c-channel blocks/box for chassis.
Having heavier robot will also help in pushing other robots around (of course provided you can catch the nimble and faster robots).
Go YouTube and look out for their worlds TP matches. And it might give you a better sensing of what you intend to achieve.
I agree. I did write this on my phone with not to much thought. What i mean to say is if the goal is to desgin a robot that leans on the heavyer side then it should be added in a way that is not extraneous. Redndance in bracing is a very good way to adchive this.
