algiogia

Yes, I figured that out. On one side they're half ground to dust ?

Yes, skid steering works fine. 42069 looks neat but would add more complexity to the model.

Thank you. I've posted some more pictures here: https://imgur.com/gallery/kn4hDSm

I recently built a custom tank and had some issue with gears and axles. The tank is probably heavier than it should be so there is a lot of friction and I am struggling to prevent the gears from grinding. There are two sets of reduction for motor. I have tried to holding the sets together using liftarms but at higher torque they seem to struggle anyway. The second issue I have is with the axles connecting the independent treads to the body of the tank. Since the treads are suspended the axles are the only thing holding it. That is not optimal as the treads spread out or even come off. The suspensions don't seem to hold much, probably due to their "mobile" nature. Any suggestions on how to solve these issues?

I'm trying to build a quad-tread tank (i.e. 2 treads per side). It powered by 2 XL motors - one per side - and I figured I would need a differential for each side so that the treads can spin at different speeds. Not a big deal really but I'm having issues keeping it compact, since the outputs of the differential need to to the front and back rather than the sides of the tank. This makes the motor-differential block either too wide or too tall to fit in the tank. Has anyone links to compact motor/diff blocks? Or any suggestions? I'll try and post some pictures later.

Thanks brunojj1. Where does the rubber band go?

Yes, sorry. I've just realized I could put a cog at the end to transfer the movement.

Thank you Didumos69, very neat. However that only has 4 positions. I was looking into a linear movement, where I can go left or right indefinitely. P.S.: your models are amazing!

Is anyone aware on a way to use the servo to make multiple steps in a given direction? I.e. rotating it 2 times clockwise would move something 2 "steps" to the left. Then rotating 2 times counter-clockwise would bring it back to the center. Basically I need a mechanism that does nothing when the motor re-centers.

I'm algiogia from UK. I've been a fun of LEGO Technic since I was a Duplo. I now use my kids as an excuse to buy more
