Well im new at this and i am building a robot for this competition and i need to lift a box that weighs around 5lbs and i was think of making a forklif but i don't know what i need to make it go up

 so like do i need a chain (to make the platform that the item will go on rise up and down) or do i need something like tracks and i need some kind of motor to right?

airman00:
any website or something?


All you need is a motorized lever , like a seesaw (except motorized)

Forklift requires a rack and pinion gears

Trumpkin:
yep you do need a motor don't use a servo unless you wanna spend big $. i would not do a forklift (very complicated). if I were you i would use windshield wiper motors because they have reasonable torque and are cheap. here is a CAD of my arm design

airman00:
windshield wiper motors are over kill  ;)

just look for motors with the torque you need , there are PLENTY out there for cheap

5 lb box is pretty hefty. and you can get windshield wiper motors at surplus stores with no shipping costs. although it may be hard to get a big enough battery, you would have to use lead acid batteries.
