I have this tank, and made a rc controller out of a wireless ps2 controller and an arduino nano.
The fan is from a server.

The vacuum part is made in a couple of hours.
The tank is not made for this, so the weight distrubution is no good.
But som how, its works quite well.
I concider to design a new vehicle to be a vacuum cleaner.
On that one i wish a hight control as well.
