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’ve been trying to keep project notes useful without turning every experiment into a report. What do you write down after a test fails? A photo and one sentence? Measurements? The guess you started with? I’m curious what actually helps you pick the work back up a week later.

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?

This week we filmed a mechanism rebuild using only workshop sound and short on-screen notes. The footage feels calmer, but two steps are probably hard to follow without narration. We’ll post a rough cut after we get the edit together. Has anyone found a good balance between showing the work and explaining it?

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.
