im not in vexu but every time i watch a vexu match i wonder why have a 24 inch bot? my first thoughts are that its harder to drive around objects since your base is bigger. there aren’t many parts that are longer 18 inches. you’d be slower because your bigger and composed of more parts. and in turning point, would it be harder to park?
just thinking about it, the only game where you’d benefit from a bigger bot would help is Skyrise for sure and maybe In The Zone.
I think that a 15inch bot and an 18inch is optimal. especially since in tower takeover, you have to drive around the poles/towers.
But why try and compact it down? One team (full of people taking college level course, so not much time to spare) has to build two different robots with a much longer auton. There is no point in making the robot smaller if it completes the same task in a bigger size that is easier to build without planning
Turning Point had an expansion limit, Tower Takeover is the first year that teather-bots are f̶u̶l̶l̶y̶ ̶a̶b̶u̶s̶a̶b̶l̶e̶ err… usable to their full potential.
You know, in VRC many of us are resulting in 25-30 holes wide robots despite having the capabilities for 18" size restrictions. We do this so we can move around the field much easier without much problem of clipping grounded field elements. By literally taking up 24^3" you’re literally making it a difficult task for your driver. If you’re VEXU and you’re having a robot taking up the 24^3" it must be a wall bot, otherwise there seriously should be no reason to be 24" wide.
when you compact things, it tends to become more simple and more efficient. and im not talking about the average team, im talking about like a top 50 team.
The problem with this is some of the current limiting the brain has with more motors over 8 motors here is an excerpt from a document I have been writing about tether bots
Yes even more so as in VEXU with 24’ 24’ 24’ Bot’s that allows you for a more standard drive base of 12’ and in VEXU skills the 448 pt skill runs requiring 0.025 Actions Per Second could be more accessible . The 15’ 15’ 15’ bot could be achieved with standard bot. The tether bot the VEXU teams would use have 6 motors each but 12 total with (4M drive 2M Lift/Claw) not much more due to the current being limited when more than 8 motors are on the robot by number of motors divided by 20(A). Having 1.6 (A) per motor. Any more motors might not get enough power as P=IV and V=IR as Ristince is the same and voltage and current go down so does power. With this VEXU could even have a tether wall bot combo if they manage to engineer a good wallbot whether that be NORCAL style or any other style that can fit in 15’ 15’ 15’ and have two bots playing the game and in doing defence making the game a 2v0. Doing this might make VEXU world champions.
I’m brand new to VEXU, but personally I’m not looking at building a 24"x 24" bot. I’ll use just enough space that my mechanisms need which so far is looking like 16" wide and 19-20" long. I don’t think its about reaching the 24" limit, but more along the lines of have the freedom to do what you need, cause y’all are right 24" isn’t really practical for the size of this field, but 19" or maybe even 20" might be if done correctly. I think VEX made these size limits to give almost unlimited freedom in design options for the big robot to help people escape the design meta and try more creative designs. Then for the small bot they do the same with the challenge of the small size limit for the other bot, so you have to find unique solutions to get around that challenge.
The 24" limit must be very helpful if you’re doing a tray bot; you could make your base normal sized (26-30 holes), but the intakes would not have to flip out at the start which is, and some of you understand, a huge pain regarding the intake compression. Also the tray segments could be way taller- instead of using 18" segments, you could use 24" segments, which 2 of these could probably hold 9 cubes.
