Hi! My team has just started making a chassis for our robot. We have decided to make a H base, to use direct-drive drivetrain, and have 6 wheels, 4 omni-wheels and 2 normal wheels in-between.
We want a fast robot that can also get over the bumps well, and we’re wondering if you would have any recommendations for the gear ratio we should use or thing we should change.
Welcome to the forum!
You state that you are making a direct drive drivetrain, yet you are asking for drive ratios. Keep in mind direct drive means that your shaft goes directly to the wheel without any gears.
You always have the option of running direct drive 200rpm on 4 inch wheels if you don’t want to use a more advanced drivetrain.
Anyhow, it really depends how you want to play the game with your robot.
Ask yourself and your team some questions
- How fast do I want my robot?
- Will it complement my drive style?
Thanks for the advice!
I accidentally put direct drive, I met a gear mesh drive train.
if you are looking for speed, use either a 7:5, 5:3 or 1:1 is fast enough if you do want to go with that, but the other ones that i stated are much faster 7:5 being 280 rpm, 5:3 being 333.33 rpm
Thanks! We decided to put the 7:5 ratio on our robot.
