So our lift is made of aluminum. we have linear slides to pick up cubes. but the linear slides are weighing the lift down. we upped the power to 200% and is still no going high enough. i don’t have any pictures for you guys. just need some suggestions before the 7th of December. Thanks.

Lol there ya go Your gears are backwards, your lift needs more torque. it needs to first power the small gear which then powers the big gear at a slower speed

ya i miss said that, it is 12:84

Why do you have linear slides to pick up cubes? a claw would be a lot lighter. [image] Deicer: Your gears are backwards, your lift needs more torque. it needs to first power the small gear which then powers the big gear at a slower speed I think It’s actually supposed to be driven gear/drivi…

this is our design. [DR4B ERS (v3) - Ultimate Passive Intake - Tower Takeover - VEX VRC]

oh, I would suggest making custom linear slides because they are much lighter than the steel vex ones. You should also use the 100 rpm torque cartridges.

how do you go about making custom linear slides?

You’ll probably need more if your lift isn’t working. Our lift is probably similar to yours and we have 8 per side.

I think your example proves my point… They use 2:1 as an example where the motor rotates twice and the driven gear rotates once Regardless, for this thread you’ll want little gear to big gear. Previously you stated big to little

you can use standoffs and high strength bearing blocks. standoffs are just smaller than high strength shafts so it creates i slide. it works quite well

@Deicer You can counter some weight with rubber bands, but eventually you would be using so many rubberbands that the arm will not stay in size at the beginning of the match. Using too many rubberbands can also cause other problems with VEX parts such as; flexing/twisting the c-channels of the arm…
