Robotic tank

I am working on designing an RC tank for a school project. my design calls for 6 motors. Two to drive the left side, two to drive the right, one to raise a front platform and one to raise a rear platform. This tank has to drive forward, backwards, turn left and right, as well as raise and lower the two platforms individually.

I am a bit lost on a circuit board that could handle controlling all sets of motors. I was thinking an Arduino Uno with some attachments but I am not sure which ones would be best.

The controller for this will be either wired or wireless, I have not decided yet.

The motor size has not been determine yet, something with high torque and low rpm's

Some guidance on a board would be appreciated.
