BTW, what is the ratio on that gearbox, and how many game pieces are you looking at lifting at a time? We geared ours down 8.45:1 (KoP equivalent gearbox), then another 32:15 (2.13:1) with chain, and drove that on a 15 tooth #35 sprocket. As I figured at the time, we had a theoretical 40A lift force of about 250 lb and a free lift speed of 2.3 ft/s. That speed seemed like plenty, as we would rarely be lifting more than a foot at a time, and we wanted to have plenty of surplus force so we could get a load of six totes with RC moving with authority. As you appear to have about a 2" sprocket, you'd need a gearbox somewhere around 30:1 to get the same force and speed.

As it turned out, we rarely lifted more than four game pieces at a time, but it was due to our inability to form interlocked stacks, not our lift that limited us.



The longer I'm involved with FRC, the less likely I am to count gravity as an ally beyond providing normal force for wheel traction. Don't just carry game pieces; hold them.

It's a 27:1 Banebots p80.
