KintThreads.

We’re rebuilding our drivetrain before our first scrimmage. The robot is about 13 lb and our current setup feels quick on tile but loses a lot of speed on carpet. For teams using 4-inch wheels, what gear ratio gave you a useful balance of speed and pushing power? I’d love to hear what you tested and what you’d change.

We checked the sprocket alignment and tension by hand, but the chain still walks off after a few hard starts. What should we inspect next?

We shared a short build diary about one mechanism decision and the tests that shaped it. It made us wonder how other teams choose which idea is worth building first. Do you reach for cardboard, CAD, or a quick physical mockup? We’d love to hear what has helped your team learn something early.
