I know you lifted the robot into the air and it *seemed* fine, but we're trying to explain some of the finer points of drivetrains to you.
Measure the motor current with the wheels in the air. It should be only a few Amps. Let us know if you don't know how, happy to explain. (What this tells you is IF the gearboxes really are tight or not. They often are, and need an hour or 2 running time, unloaded, to loosen up. You can lose 25% or more of your power here!!!)
Please, please, tell us the sprocket sizes top & bottom! And how big those wheels are! We are problem-solvers by nature, we just can't help it, but a problem with insufficient data is our version of Hades. Have pity on us, tell us...

We may have gotten it working today, but we are going to test it tomorrow. We have an assembly, so we were more focused on getting the kinks worked out to drive in the gym, so we will test the adjusted sprockets tomorrow, and I'll get back to you. All of you, thank you so much for the help!
