I have built a robot that can launch preloads in roughly 7 secs. (no designs will be released) and is fast around the field. But, what about lifting, in Texas just about every finals mach has swept the field with 30 - 15 secs. to spare, just about enough time to elevate. So here is the question I have been faced with: will it be better to free up some motors and make a high lifting mechanism and shoot preloads a little slower, or keep the fast preload time (14 sec.)? Also, at worlds, how important will a lifting mechanism be? I think it will be just like last year with autonomous, the mach will will be decided by who elevates.
ok
- I think elevating will be essential, and I think that your going to need a lift to win at really competitive events
- have you used all of you motors (as in all 12) or are you using pneumatics
if you are using pneumatics and can get more pistons use those to make a lift.
if you are already using more than 4 motors on your shooter I think you can safely do 4 without a huge hit to speed
I would definitely try and do it. I just today tried taking off two motors to un y-split my base and see the effects on the flywheel. The base now works, and the flywheel only has a minor hit to speed due to it being tuned for 6, and running on 4. You also will draw more current, so battery voltages will have to be higher than for 6 motors.
Elevating is going to be important, but the closer we get to worlds, the more people that are going to be lifting bots. At this point, we may not have enough good teams that can be reasonably lifted and still perform well. Also remember that if you add a lifting system on a robot that you did not originally intend a lifter to be on, you might run into more tipping and friction problems. You may have to slow down your drive too haul around the extra load.
Good luck on the build!
Ok, I have been thinking about the same thing, lifting will be needed. But what about worlds, will there be enough lifting bots to not need an elevator yourself? I think that most qualification matches will be able to be won with out lifting, and if you are one of the pickers than could you pick a lifting bot?
I think that at worlds, the alliances that win will have a slightly slower lifting robot paired with a fast robot clearing the field. It really depends on what you want your role to be on the alliance. and I don’t think qualification matches will need a lift to win but it will be essential during eliminations especially at worlds.
Ya, I would agree. I just looked at a scoring app, and if the bonus balls were split split evenly (5 in each goal), you would need 53 balls in the goal to beet them (assuming no balls leave the field and the opposite team has a high elevate, and they score all the balls left on the field).
Sorry, i did not see this, I am using 11 motors, 6 on the launcher(s) which could be slowed down with 4 motors, leaving 3 motors.
