Currently we are exploring options for articulating our intake on the end of our elevator with about 90deg of travel. While pneumatics are an option, we’d prefer to have variable control over the position of the wrist. So the next option we see is something like a bag or 775 motor. The issue we are running into is getting the rpm down to a manageable level in a relatively compact package. So my question today is what would be a good gearing option for a wrist like this? We’re probably looking at similar loads to wrists from power up last year. What setups did teams run on their bots?
Using the JVN design calculator, even a 256:1 reduction with a 775 will result in the wrist going 90deg in 0.25s (albeit at full speed/power). This seems rather fast to me. Thoughts?
