The Versaplanetary has 2 10:1 stages for 100:1. It then goes into a 24t gear which goes into a 60t gear which brings the reduction to around 250:1. A chain is then driven by a 12t Sprocket which goes to a 36t sprocket making our end reduction about 750:1.
The reduction was pretty much perfect for the arm (It originally had a giant cylinder mounted to the back). The biggest issue that we cantilevered a shaft which had to deal with loads that big on a plastic gearbox.
