Go to Post The great thing about autonomous mode is that it doesn't require any additional effort from anyone else on your team... (You could do that yourself...but I've noticed that people will usually offer to do it for you, rather than let the programmer touch power tools.) - jgannon [more]

Re: Worm Gear Gearbox

Team 107 also used a worm drive transmission a few year ago,it work ok but there are things to be aware of. The main issue is your reduction should not exceed 50 to 1 on the worm ,for the reason that it will not back drive or coast. You can compensate for this by adding a ramp down in your code, but in humble opionion worm tranmisson is better suited for arms or lifting or any application where there are not sudden loads ,like stopping a moving robot.
I may still have one of the transmission we used if you would like me to sent it to you to look at I would be happy to help. I will try to post some pictures of a new worm tranny I designed over this summer If anyone would like to see it.

thank jim schaddelee
