67101C Early Season Change Up Reveal. This is our early season reveal for the Vex 2020-2021 game, Change Up. We have limited parts to build with so certain areas aren’t exactly how we want them (like the plate on the back that sticks out).
You think that there is extra friction in the drivetrain that is making all the noise? We can mess around with the spacing and see if that makes it quieter. Thanks for the feedback.
Yes, a couple of ways we test for friction is putting a shaft encoder on a wheel that’s not being directly driven and find the rpm value, and compare it to the supposed ratio value. Another way we test is programming the robot to drive straight along a line. One of the factors that might cause a robot to drive crooked is increased friction. Other than that large amounts of squeaks should be a tell for excess friction.
depending on how complicated the gearing is. if you have direct driven wheels it could free-spin for 30 seconds, but once you start getting gears in I doubt you’ll be able to free-spin for more than 10 seconds, and even less if you have a lot of gears.
Ngl, if you 3d print a couple of V5 motors at 75% scale and attach in random places on your robot… It’s gonna be hilarious when some inspectors will notice that…
