Redesign, 36mm question.
Turns out we have to resort to plan B, we have to abandon our forklift due to weight and time issues.
Luckily we have prepared for this to happen, and have built an arm incase the forklift doesn't work out, or if we want to try a different manipulator (both built from 80/20, can be switched in under 5 minutes).
Now, I was thinking about using two FP motors with the KOP gearboxes. BUT, I was also thinking at the same time that it might be overkill, and we are also starting to face space constraints. Now, we HAD 2 42mm 64:1 gearboxes for the FP motors, but we wound up returning them because we decided not to use them before we even opened the box. Seeing as this is the 6th week, and since we operate off of purchase orders, we can't sit around waiting for another order from BaneBots to come in.
This brings me to the 64:1 36mm gearboxes given to us in the kit. Could two power an arm that weighs about 15lbs max? We can reduce it even further with an 11 tooth sprocket on the gearbox, going to a 30 tooth sprocket on the arm. I think it'll have more than enough torque to lift it, I just want some input from somebody who has a little bit more experience with them, I've never ran them before.
Thanks
