I have seen threads that say 2 motors are better than 4 motors and the opposite. My team and I have gone back and forth trying to decide which is better. What do you think?

Honestly I defiantly see some 6 motor designs popping up. Highly defensive strategies that will probably sacrifice either making stacks quickly or scoring posts quickly.

X-Drives go faster, but have less torque.A X-Drive is about the same as having a 1.41:1 gear ratio. If you build 4 motor x-drive and a 4 motor base, the X-Drive will beat it in a race but lose in a pushing battle.

I can see how that might be possible, especially at a light load. It would definitely be the case if the motors were being controlled by speed of rotation. I’d be curious to see the experiment done with a decent sized load. Based on A = F/M… you know what top speed IS going to be faster on the X dr…

I don’t think it’s reduced torque per say - although the effect is the same. The motors are twisting just as hard, but they are pushing at a 45° angle, so force in the forward direction = force × Sin(45°). Same result though.

this was a joke I posted a while below, but I’m thinking about it for real now: a 30 pound robot with 8 motors for drivetrain geared to insane ratios. Is this worth it?

Mine was under the assumption that V5 is approx 2.5* stronger than a standard 393 motor.

for the 100RPM to 100RPM settings on both. The 200RPM setting is still overall stronger than the high speed gear set on the legacy motors, but not that much stronger.

Hi There, I haven’t been here for a while, and missed this explosive conversation. I’ll try and sum up a few things that I’ve noted, as well as put in a few of my own views (instead of studying for exams) Holonomic or Not In my opinion, it’s never ben necessary to have a holonomic drive, and wit…

3 wheeled drive. (Or in this case, 3 motored). [image] (Not mine, I just found it online):wink: Front 2 wheels are main power, and make it turn. Also the back wheel would have to be an Omni wheel. Probably not very viable, but it would work if you just had to have access to an extra motor. I t…
