Unofficial Response to: Gear Ratios

Advanced gear question

One of my team mates thinks a 1:3.125 gear ratio for the arm is impossible, we use a 1:5 right now for our arm. Many people on the forum say that they have that gear ratio, so can someone explain how they do it?[what gear arrangement]
Thanks

This is a 1:5 gear ratio using speed motors. The gear ratio for the speed gears is 1:1.6. If you do the math (5÷1.6) you get a 1:3125 gear ratio.
