Could you design a drivetrain where the left wheels are connected by a gear train with one motor on the front left wheel and the right wheels are connected by a gear train with one motor on the right rear wheel? It seems odd, but since the power is transferred to both wheels by the gear train, would it actually make a difference? Thanks!
Yes.
It is easier if the front and rear wheels are the same size.
My VRC students did that for Change-Up. It was especially interesting since the front and wheels were different sizes for that design. The programmer did a great job with the different motor speeds, but the different gear ratios (torque imbalance) still lead to some … interesting … handling behavior.
Don’t be afraid to try something different.
Good luck!
This is doable. The only issue is weight distribution. The front of the robot will have more weight on the front left wheels and the back of the robot will have more weight on the back right wheels. This weight difference can cause uneven traction differences between left and right side which might make the robot not drive as straight. But this is all theoretical since my kids haven’t tried this set up before. Worth a try and test to see. Cheers.
