I currently have a robot that can externally stack about eleven cones on a mogo. Would it be worth it to change the design in order to be faster and stack the cones internally, but only be able to stack 7 cones?
It would depends on the time you take on stacking 11 cones externally. For example, if you can stack 11 cones on a mogo and put it in the ten point zone in 45 seconds, then that would be the better choice, unless you can stack 7 cones on more mogos faster than you can stack externally.
@6318C_Michael The current eleven cones is extremely slow, and the redesign for the robot will take a week at most
Well then it might be worth it. If you realize you're pretty much at the ceiling of your current design then you should redesign. Just make sure the rebuild doesn't end up taking much longer than it should (that was our problem this season, we did a rebuild of some type after each competition)
@biglesliep Are you talking about redesigning your robot between now & Worlds? If that's the question, the answer is NO. DON'T DO IT. You will not have enough time to be an expert driver on the new design, plus work out all the kinks & bugs that will inevitably appear.
100% Disagree. If you have 1-2 hours a day you can put into your robot, definitely do so if it is a major improvement. They don't call them Worlds rebuilds for nothing.
My lift is a four bar that goes into a chain bar. These two are not mechanically linked. The redesign will involve shortening the chain bar, and moving it down. Currently, we have to drop the cone for internal stacking for the first four cones. The new design will allow me to brace the lift better. Also, the program will be the exact same.
If you have enough supplies and a large enough team, I recommend breaking into two groups. One group works on improving the old robot and one works on making the new one. Even if you don't need to rebuild the entire robot, build every new subsystem and test them out. Then simply swap out the two pieces and test. If it works, great! if it doesn't, you can go back to your old bot which was receiving upgrades anyway.
I'm not sure if I'm correct or not, but is your four bar using compound gearing? That is one of the reasons why the lift is slow imo. If you have spare money, I'd recommend swapping all of the lift to aluminum to ease the stress on the motor. this can allow you to gear the four bar at a more reasonable speed like 1:7 or 1:5. As for the cone dropping issue, you can do that simultaneously with the changes to the four bar as they are separate.
Lots of people talking about if OP has enough time left... really, the number of days does not matter so much as the number of hours. I probably work 7 hours/day 5 days/week but it's 7 days/week right now on spring break. That's much different than having 2 meetings in a week, 3 hours each. It makes a huge difference.
@The Electrobotz If you have enough supplies and a large enough team, I recommend breaking into two groups. One group works on improving the old robot and one works on making the new one.

Since we only have one team going to Worlds, we are keeping our old bot and making a new one at the same time.
