I know that this topic is a bit oversaturated with new posters but I have a genuine question. My team is planning on running a 77w drive train geared 400 on 3.25. We only really have 200 rpm cartridges. I would like to try to get some 600 but for now that out of the question. I have attached a schematic but it seems really in efficient and bulky. I think going like this though would have a good balance of space and speed although it would only have 4 wheels on the ground. Any way i could make it smaller but at a similar speed?
My main issue with this is that by using a 5.5w motor mixed with 11w motors, you’re putting a lot of stress on the less powerful motor which may lead to faster overheating or burnout.
I also recommend using more than just 4 wheels, this helps reduce the amount your robot sinks into the tiles and reduces friction (spreads out the weight).
Yes! You can move the wheels and adjust the location of the gears. This shouldn’t change the speed either!
You could also find another gear ratio that is similar to your current one.

There’s realistically no other option to make it smaller unless you run 600 rpm as then you gear down and can use smaller gears and bigger gears on the wheels. Unless your happy with a lot slower speed on the wheels
This setup which im assuming uses staggerd 72t gears doesnt really work. The spacing in cad is just slightley off which could cause gear meshing issues under high torque senarios.

There is no need for 77w. I had a 22pound bot on the same linear speed you are describ8ng and i never had over heat issues or accel issues at 66w. I would find a bettwr usw for your motors like splitting intake for faster intake speeds or making a wallstake mech
