I need to make a forklift with about 2 inches of travel. I like the idea of using a servo as I can mooch power right off the Arduino. The other reason is I would prefer to direct connect without gears or pulleys as latency could be a deal breaker. I don’t want to mount anything to the slotted slab as there is no clearance for it to recess into the shelf at the bottom (the slot bottoms out just above the shelf).
The problem as I see it (aside from the mechanical linkage design), is to convert the rotary motion of the servo to a linear up and down motion. Here’s an illustration of the gizmo. Any hot construction tips appreciated.
