Motorized tank WIP 2
Here is my second installment of WIP for my motorized tank. I completely gutted my WIP 1, and have a newer idea and version.
About this creation

A front view, showing the two front M-motors, the IR recievers, and the motor to control the turret movement.


A back view, showing the battery box, and the two back motors. Also, those wires that seem to go everywhere, those are the LED lights.


And finally, a bottom view. Beneath those plates in the front, all the wires are going under that. It gets really confusing, but when you finally lock something down and not have to deeal with it again, it helps. Right now, I still have a lot of work to do.
A question for vistors:
How should I motorize the turntable? I am completely stumped. Any help is welcome. Thanks for viewing!

Your tank is huge so it will not drive with that powerless m-motors. You should use some xl-motors.

Simple click this ldd file to see how to oporate the turn table file:///C:/Documents%20and%20Settings/Leone/My%20Documents/Downloads/ddddd.png something like that but closer

Quoting George Staples Ah I see your problem. You cant drive a worm gear by putting a gear to it. The friction from the worm gear is way to great to drive it directly from a gear. The best way to use a worm gear is to drive the shaft it is connected to either with other gears, or direct drive. I think direct drive gives you the best torque for friction loss. In your case, if you want to keep a similar setup to what you have now, I suggest you take the drive off to the side, and either drive the side of the turntable via universals, and worm gear drive. (You might have to move the motor back a stud or two.) or you can take the drive off of the motor via 12tooth gear, add another 12tooth gear to the side, and then add a 20tooth gear perpendicular to that, with a worm gear on the same shaft.
I see now! I think I will try to power the drive shaft the worm gear is on with the motor, via a few gears, and that may work. Thanks for the help, your name will be recognized as well as full credit for the turntable! I will have to try that first, though.

Quoting George Staples I see 4 possible solutions to your turntable off the top of my head. Two of which involve moving the motor. 1)Get some gears, and make a drive shaft off of the motor to one side of the turntable, and use a worm gear for drive. 2)Put one of the 12 tooth wider gears on the drive, and then a 20tooth wide gear flat, from drive to turntable. (You might have to reposition the motor slightly, or use 2X 12tooth gears) 3)Move the motor to one side or another, and then use the worm gear drive. 4)Put the motor on the turntable its self, and have a drive go down in the center and turn inside the black part.
Yeah. See, right now, I am using a worm gear that is both connected to the motor by a twelve tooth gear and the turn table itself. However, the motor seems to have trouble in turning the worm, and often, it sends the part flying.
