If I remember correctly, speed is less important than last year, both because it is weighted less, and also because of the new rule against going backward (which for good teams tended to make distance scores near-perfect last year, since you could just overshoot and then reverse).rockgirl365 wrote:Finally I have a copy of rules for EV!!

To build on that, speed should be the least of your worries this year. A 2 second difference in error translates to 2 seconds of travel time. For perspective, at nationals the top 6 teams had 2-7 cm errors, so as long as you are in that 3-6 second range ur in great shape in that sense. The big thing this year is the bonus. It translates to about 20cm (so if someone is on the dot and someone is 20cm off and got the bonus, they tie), but it is very hard to implement well, so this will make or break the top teams.Unome wrote:If I remember correctly, speed is less important than last year, both because it is weighted less, and also because of the new rule against going backward (which for good teams tended to make distance scores near-perfect last year, since you could just overshoot and then reverse).rockgirl365 wrote:Finally I have a copy of rules for EV!!

What do you have? If you have metal, use metal. If you have wood and wood-milling machinery, use wood. I strongly believe that the material has little effect on the finished device: use what you are comfortable with. For me, that happened to be carbon fiber and 3d printed parts, but my chassis is no better that one made of wood and has no advantage (weight really doesn't matter, I prefer more weight anyways)hqearth wrote:Hi!
My teammates in this event have no idea where to start. I was wondering where would be a good place to begin and what materials to buy. I already checked out the wiki page. If anybody has any advice for people that are completely new to this event, anything would be appreciated. Thank you!
I would recommend planning out all the aspects of your design before considering the implementation. So first off decide on your counting mechanism (wing nut, stepper motor, encoder) and your steering mechanism. Then consider the implementation; which motors you want to use, which microcontroller, what kind of bearings and gears/gearing you will use, and what your base material will be (3d printed,wood, plexiglass, combination). This is just my preference, and I think it really helps complete the task efficiently and qualitatively. Good luck!hqearth wrote:Hi!
